WiziShop SEO migration: the complete guide

You're about to migrate your online store to WiziShop, or you've just made that decision, and a dull fear is nagging you: «Will I lose my SEO?» I know this fear, I've been with it dozens of times, and I'm going to be honest with you right from the start: yes, a poorly prepared migration can wipe out months, even years of SEO work. But a well-orchestrated, methodical, rigorously planned migration can not only preserve your positions, but sometimes even improve them.

The problem is that most guides to SEO migration remain abstract, disconnected from the specific reality of a platform like WiziShop. In this article, I'm going to give you a concrete action plan, structured in three phases (before, during, after), with actionable checklists, tracking charts, and my personal opinion on the critical decisions you're going to have to make. Whether you're coming from Shopify, WooCommerce, PrestaShop, Magento or any other CMS, this guide is designed to secure your transition to WiziShop without leaving your organic traffic in the lurch.

Key points to remember from this article

• Successful SEO migration depends on 80 % before changeover URL mapping and inventory are the most critical steps.
• Visit 301 redirects are the heart of the system, but they're not enough on their own: content, internal links, tags and structured data must also be preserved.
• Every page that generates traffic or backlinks must have an equivalent on the new site, otherwise you'll permanently lose the SEO value it had accumulated.
• A temporary drop in traffic is normal after any migration, even if perfectly executed. It must be controlled and limited in time (usually 2 to 6 weeks).
• Post-migration follow-up in Google Search Console is mandatory: this is where you'll detect 404 errors, broken redirects and pages excluded from the index.
• Redirect all old URLs to the home page is the most frequent and destructive mistake. Every old page must point to its exact equivalent on the new site.
• The best time to migrate is when low-season period for your business, to minimize the commercial impact of any temporary downturn.

Let's start by understanding why migration is inherently risky for your SEO.

Understanding the SEO risks of migrating to WiziShop

Migration means a change of signals for Google

Google doesn't see your site as you see it. It sees URLs, HTML code, tags, links, response times and structured data. When you migrate to WiziShop, you potentially change all these signals at the same time: URLs change structure, HTML templates are different, loading speed evolves, internal meshing is reconfigured, title tags and meta-descriptions can be automatically regenerated by the new system.

For Google, it's as if your old site has disappeared and a new, unknown site has taken its place. This is precisely what we're going to prevent, by building bridges between the old and the new via redirects and content preservation.

Migration scenarios

Not all migrations present the same level of risk. Here are the four most common scenarios, ranked from least to most risky:

• CMS changeover only (same domain, same URL structure): the lowest risk, provided that redirects are correctly configured for URLs whose format changes.
• Change of CMS with change of tree structure (new categories, new hierarchy): moderate risk, as URL mapping becomes more complex.
• Change of CMS with change of domain high risk. Google needs to understand that the old domain and the new one are one and the same. Use the change of address tool in Search Console.
• Complete redesign + migration (new design, new tree structure, new CMS, sometimes new domain): maximum risk. This is the scenario I'd advise against most strongly, because you're changing too many variables at once, making diagnosis impossible in the event of a problem.

My advice is categorical: never do a visual redesign and a technical migration at the same time. Migrate first, stabilize, then recast. Or recast first on the old CMS, stabilize, then migrate. But never both at the same time.

The most common causes of traffic loss

I've accompanied enough migrations to identify the mistakes that recur with almost disheartening constancy:

• Incomplete redirections Only the main pages were redirected, but dozens of secondary pages (product sheets, blog posts, deep category pages) were forgotten. Each omission generates a 404 error and a loss of SEO value.
• Deleted pages without equivalent A product that is no longer sold, a category that no longer exists on WiziShop. Instead of creating a redirect to the most relevant page, the page was simply deleted.
• Shortened or duplicated content Category descriptions, carefully written and optimized on the old site, have not been migrated to WiziShop. Or worse, they were replaced by generic, superficial descriptions.
• Poor management of filters and facets Navigation filters (size, color, price) create URL variants which, without proper processing, generate hundreds of pages of duplicated content.
• Improperly configured canonical tags or robots.txt tags WiziShop: parameter errors in WiziShop that block the indexing of essential pages or create contradictory signals.

Now that you understand the risks, let's move on to the phase that determines 80 % the success of your migration: preparation.

Before migration: audit and preparation

I repeat: a successful SEO migration is a prepared migration. The preparation phase is the longest, the most tedious, and the most crucial. Every hour invested here will save you weeks of troubleshooting after the switchover.

Make an SEO inventory of existing sites

Before you move anything, you need to know exactly what you own. It's like moving house: you don't put your stuff in boxes without taking an inventory of what you're taking with you.

Export your indexed URLs from Google Search Console («Pages» section). This list gives you all the pages that Google currently knows and indexes. This is your basic repository.

Crawl your complete site with a tool like Screaming Frog (free up to 500 URLs) or Sitebulb. The crawl will reveal pages that Search Console doesn't always show: orphan pages, existing chain redirects, hidden errors.

Identify your high-value pages in Google Analytics or your audience measurement tool. Filter by organic traffic and revenue generated. These pages are your most valuable assets, the ones you need to protect as a top priority.

Export your backlink profile with Ahrefs, Semrush, or even the «Links» section of Google Search Console. Pages that receive quality backlinks have considerable SEO value. If these pages disappear without redirection, you lose not only the direct traffic, but also all the authority these links conveyed.

Defining the future architecture of WiziShop

Once the inventory is complete, draw up the structure of your future WiziShop site. Which categories will you keep? Which will you merge or delete? How will you organize your sub-categories?

My recommendation is to maintain the winning structure as far as possible. If your current categories are generating traffic and sales, don't change them on an aesthetic whim or out of a desire to «start from scratch». Every architectural change is an additional risk. Only change what objectively needs to be improved.

Also check WiziShop's URL creation rules. How does the CMS generate slugs for products, categories and blog pages? If your old site had URLs like monsite.fr/shoes/white-sneakers and WiziShop generates URLs such as monsite.fr/product/white-sneakers, the mapping will have to take this into account.

URL mapping: the most critical step

URL mapping is a correspondence table that associates each old URL with its new URL on WiziShop. This is the most important document in your entire migration. Without it, your redirections will be approximate, incomplete or anarchic.

Special cases of mapping

Some situations require special consideration:

• Products discontinued or out of stock Don't let them become 404s. Redirect them to the parent category or to a similar product. If the product has no equivalent and generates no traffic or backlinks, a 410 (Gone) response is acceptable.
• Product variants If your old site had separate URLs for each variant (size, color), check how WiziShop handles these variants. If WiziShop uses a single URL with parameters, redirect each old variant URL to the main product URL.
• Blog pages Blog pages are often overlooked in e-commerce migrations, even though they sometimes generate more organic traffic than product pages. Check that WiziShop offers blog functionality and that the URL structure is compatible, or prepare the necessary redirects.
• Filter and sort pages If your old site indexed filter pages (by size, color, price), decide whether you want to keep this indexing on WiziShop or de-index these pages and redirect the old ones to the main categories.

301 redirect plan

301 redirects are permanent instructions that tell Google: «This page has definitely moved to this new address. Transfer all SEO value to the destination.» This is the central mechanism of any SEO migration.

When to use a 301 : each time a page changes URL but an equivalent exists on the new site.

When to use a 410 : when a page has no equivalent, generates no traffic and has no backlinks. The 410 response tells Google that the content has been intentionally removed, and that it can remove it from its index.

Basic rule: never redirect all your old pages to the home page. Google interprets massive redirects to a single destination as «soft 404s» and does not transfer SEO value. Each old page should point to its most relevant equivalent.

Avoid redirect chains: if page A redirects to B, which redirects to C, which redirects to D, Google loses value at every link. Check that each redirect points directly to the final destination.

Test your redirects before going live. If WiziShop allows you to set up a staging or pre-production environment, activate your redirects and check them one by one on your most important pages.

Preparing content for migration

Content is a major SEO asset, and it needs to be migrated with as much care as URLs. Here's what you absolutely must preserve:

• Category descriptions These texts, often rich in keywords and carefully optimized, are frequently lost during e-commerce migrations. Export them, and reintegrate them into WiziShop.
• Product sheets : titles, long descriptions, short descriptions, product FAQs, feature tables. Don't «simplify» your content during migration. If your product sheets were 500 words long on the old site, they must be at least 500 words long on WiziShop.
• The images Renamed images or lost alt tags are wasted SEO content.
• Internal meshing WiziShop: the links you've inserted in your product descriptions, blog posts and category pages need to be updated to point to the new WiziShop URLs. An internal mesh full of broken links is a sign of negligence that Google will penalize.

Preparation is complete. Let's move on to the big day.

During migration: WiziShop settings and technical issues

Essential SEO settings in WiziShop

WiziShop includes native SEO features that need to be configured correctly from the outset:

URL structure : Check and adjust the URL structure for your products, categories and blog pages. Choose short, descriptive URLs, without special characters or accents.

Title tags and meta descriptions : WiziShop lets you customize these tags for each page. Don't leave the default values. Use the optimized tags from your old site, or improve them if they were insufficient.

XML Sitemap : check that WiziShop automatically generates a complete and up-to-date XML sitemap. This will be one of the first elements to be submitted to Google Search Console after the switchover.

Robots.txt file : make sure there are no unintentional blocking instructions. In particular, check that category pages, product sheets and the blog are not blocked.

Structured data : WiziShop implements automatic structured data for certain content types (Product, Breadcrumb, Organization). Check that they are active and correctly configured with Google's Rich Results Test.

Tags canonical : make sure that each page has a canonical tag pointing to itself, and that filter or sort pages have canonicals pointing to the main category.

Filter, facet and sort management

This is a thorny issue on all e-commerce platforms, and WiziShop is no exception. Navigation filters (size, color, price, brand) create URL variants which, if indexed unchecked, generate an explosion of pages with thin, duplicated content.

My recommendation is as follows:

• Filter pages corresponding to a actual search intention (for example, «women's white shoes») can be indexed, provided they have unique content and an optimized title tag.
• All other filter combinations (size 38 + white color + price 50-100€) must be in noindex or blocked via robots.txt, with a canonical tag pointing to the main category.
• Sort parameters (by price, by popularity, by novelty) must never be indexed.

Performance and Core Web Vitals

One of the potential benefits of migrating to WiziShop is improved performance. As a hosted solution, WiziShop manages the server infrastructure and basic technical optimization. However, you remain responsible for certain elements:

• The images compress them before uploading them. Use WebP format if WiziShop supports it. Images of up to 3 MB each will wipe out any performance gains on the server side.
• External scripts Every tracking pixel (Meta, TikTok, Pinterest), every third-party application and every widget adds code that slows down your site. Integrate only what's really necessary.
• Test on mobile first Google evaluates your site on its mobile version. Use PageSpeed Insights to obtain your mobile score and follow the recommendations.

Tracking and tags

This is the aspect most frequently overlooked during a migration, and the consequences can be serious - not for SEO directly, but for your ability to measure the impact of the migration.

Before switching over, make sure that these items are correctly configured on WiziShop:

• Google Analytics 4 Check that the tag is in place and that e-commerce events (view_item, add_to_cart, purchase) are correctly reported.
• Google Tag Manager If you use it, recreate your container with all the necessary tags.
• Advertising pixels Meta Pixel, TikTok Pixel, and any other retargeting pixel you use.
• Cookie consent management Make sure your consent solution (Axeptio, Didomi, Cookiebot) is fully integrated and RGPD-compliant.

Without functional tracking, you'll be blind during the post-migration phase, unable to measure the extent of any drop in traffic or conversions.

Online check: the D-Day checklist

Tipping day is a tense time, and that's normal. Here's exactly what you need to do, in order, to minimize the risks.

Just before the switch

• Check that the staging or pre-production environment is up and running. noindex (It would be disastrous if Google indexed your test site before it was ready).
• Make a complete backup of your old site (files, database, content, images). If something goes wrong, you need to be able to go back.
• Make a last crawl of your old site with Screaming Frog to get a final snapshot of URL status.

At the switchover

• Tilt the DNS to WiziShop if necessary.
• Check that the HTTPS certificate is active and functional. No mixed content (HTTP and HTTPS on the same page).
• Force redirection www to non-www (or vice versa) according to your choice.
• Activate all 301 redirects according to your mapping.
• Test manually 10 to 20 critical URLs (your highest-traffic pages, your pages with the most backlinks) to check that redirects are working properly.

Just after

• Submit the new sitemap in Google Search Console.
• Use the « URL inspection »Search Console to request indexing of your 10-15 most important pages.
• Check the robots.txt in production (votresite.fr/robots.txt) to confirm that it's not blocking anything important.
• If you have changed domain, use the change of address in Search Console.
• Check the canonical tags on your main pages.
• If your site is multilingual, check the hreflang.

After migration: stabilize, correct, recover

The days and weeks following the changeover are a period of intense vigilance. It's now that invisible errors become apparent, and it's now that you need to correct them quickly.

Search Console tracking for the first 30 days

For the first month, I recommend that you consult Google Search Console daily. Here's what to look out for :

The cover report : observe the evolution of the number of indexed, excluded and error pages. A sudden increase in 404 errors indicates missing redirects. Pages «excluded by a noindex tag» when they should be indexed indicate a configuration problem.

404 and soft 404 errors: every 404 error is an old URL for which no redirection has been set up. Correct them immediately by adding the missing redirects.

Variations in impressions and clicks: a temporary drop is normal and expected. What's not normal is a drop that worsens after the first two weeks. If the curve continues to fall beyond the third week, there's a problem you haven't yet identified.

Loss analysis and prioritization

After two or three weeks, you'll have enough data to identify which pages have lost positions and which keywords have dropped. Sort them by impact (lost traffic multiplied by conversion rate) and prioritize them.

The most frequent causes of post-migration losses are :

• From missing content The category description, product FAQ or optimized text that existed on the old site has not been migrated.
• A broken internal mesh Internal links still point to the old URLs (which redirect, of course, but each redirection is one less link in the value chain).
• From unintentionally modified title tags or meta descriptions by WiziShop's default templates, which are less optimized than those on the old site.

Reclaiming and reinforcing authority

Your existing backlinks are probably still pointing to your site's old URLs. If your redirects are correctly configured, SEO value is transferred, but a redirect is never as effective as a direct link. For your most valuable backlinks, contact the sites that link to you and ask them to update the URL to the new address on WiziShop.

If certain pages with high backlink value don't have an exact equivalent on the new site, consider recreating them. The authority conveyed by these links more than justifies the effort.

Finally, don't put your content strategy on hold during the migration. Keep publishing blog posts, buying guides, comparisons - any content that enriches your site and sends vitality signals to Google.

How long does it take to recover?

This is the question on the lips of every migrating e-tailer, and here's my honest answer:

• Clean migration (full redirects, content preserved, no domain change) : 2 to 6 weeks to return to pre-migration traffic levels, sometimes even better if WiziShop offers better performance.
• Migration with a few omissions (incomplete redirects, partially migrated content) : 2 to 3 months, provided that the problems identified are quickly rectified.
• Botched migration (no mapping, redirects to home, lost content) : 6 months or more, And in the worst cases, some positions are never recovered.

Factors that speed up recovery include perfect redirects, fully preserved (and even enhanced) content, a faster site than the old one, and rigorous post-migration monitoring.

Mistakes to avoid

I'm going to be direct and to the point on this section, because each of these mistakes alone can turn your migration into a catastrophe.

Redirect everything to the home page. This is the most frequent and destructive error. Google interprets these redirects as «soft 404s» and doesn't transfer the SEO value. The result: you lose all the benefit of your backlinks and ranking history in a single decision.

Remove categories that were generating traffic. If a category ranked well on Google, it had value. Don't delete it just because you want to «simplify» your tree structure. Find an equivalent on WiziShop, or redirect it to the most relevant parent category.

Change all URLs without creating a mapping. Some site owners take advantage of migration to «start from scratch» with new URLs. Without mapping and redirects, this is SEO suicide.

Set site to noindex by mistake. It happens more often than you might think. A setting forgotten in staging mode remains active in production. Check, recheck, and have someone else check.

Forget about blog pages, guides and FAQs. Informational pages are often the poor relations of e-commerce migrations. Yet they frequently generate a significant share of organic traffic and carry numerous backlinks.

Simultaneous migration + redesign + new SEO strategy. I've said it before, but I'll say it again: never change more than one variable at a time. If you change everything at once and traffic drops, you'll never know what caused the drop.

Complete checklist: before, during, after

So that you can follow the whole process without forgetting anything, here's a checklist organized by phase:

Answers to the most frequently asked questions

Will I lose my SEO by migrating to WiziShop?

Not necessarily. A well-prepared migration, with full URL mapping, correctly configured 301 redirects, and fully preserved content, can be achieved with minimal and temporary loss. What causes SEO loss isn't the migration itself, it's a poorly executed migration.

Should I keep the same URLs or can I change them?

Ideally, you should use exactly the same URLs. If WiziShop imposes a different structure, mapping and 301 redirects will compensate for the change. But every URL change is an additional risk, even with perfect redirection. Keep what you can.

Are 301 redirects enough?

They're essential, but not enough on their own. You also need to preserve content, internal linking, title and meta tags, structured data and site performance. Redirects transfer the value of old URLs, but if the destination content is empty or mediocre, that value will quickly be squandered.

How to migrate a blog to WiziShop without losing traffic?

WiziShop offers integrated blog functionality. Recreate each blog post with full content, images, optimized tags and internal linking. Set up 301 redirects from old blog URLs to new URLs on WiziShop. If the blog's URL structure changes (for example, from /blog/my-article à /actualites/my-article), the mapping must cover each item individually.

What should I do if I notice a drop after migration?

A temporary drop is expected and normal. If it persists beyond 3-4 weeks, check in this order: 404 errors in Search Console, broken or chained redirects, missing content on affected pages, misconfigured canonical tags, and the loading speed of the new site.

Do I have to migrate in low season?

Yes, absolutely. If your business experiences seasonal peaks (Christmas, sales, Black Friday), plan your migration during an off-peak period. A temporary drop of 15-20 % in the off-season is infinitely less costly than an equivalent drop during your sales peak.

Should I call in an SEO expert?

It all depends on the complexity of your migration. If you have fewer than 50 products, no domain change, and a simple structure, you can probably manage the migration yourself by following this guide. If you have hundreds or thousands of products, a domain change, a tree overhaul, or if your organic traffic represents a significant proportion of your sales, calling in a professional is an investment that is more than justified. The cost of expert guidance pales in comparison with the cost of months of lost organic traffic.

What you need to remember for a successful migration

If I had to sum up this whole article in three basic principles, here's what I'd say.

First, prepare before you act. Existing inventory, URL mapping, redirect planning and content export represent 80 % of work and 80 % of success. Never rush this phase under the pretext of going fast.

Secondly, don't lose anything along the way. Every URL that used to generate traffic or carry backlinks must have an equivalent on WiziShop, with a correctly configured 301 redirect. Every category description, every optimized product sheet, every blog post must be migrated in its entirety. Lost content is destroyed SEO capital.

Third, watch like a hawk after the switchover. The first 30 days after migration are critical. Google Search Console is your control tower. Every 404 error detected must be corrected within hours, not days. Reactivity during this period makes the difference between a migration that stabilizes in two weeks and one that drifts for months.

A migration to WiziShop is not a leap in the dark. It's a planned, marked-out, secure passage, which can result in a site that performs better, faster, and is better positioned than before. But this can only happen if you treat the migration with the seriousness, method and attention to detail it demands. You now have all the keys you need.
