Website Migration to WordPress Without Losing SEO

Migrating a website means moving what Google remembers, not just the design

An established website carries invisible assets: URLs Google has indexed, links from other sites, and pages people find every day. Move a site carelessly and those assets disappear quietly: old links return 404 and traffic drops with no obvious cause.

Our website migration to WordPress starts with an inventory of everything the old site has, a plan for where every URL goes, complete 301 redirects, and repeated checks before switchover. The goal is to keep as much of your existing ranking as possible and hand you a site your team can edit.

To be straight with you: nobody controls Google’s algorithm. Rankings can move up and down for a few weeks after a migration. We monitor and fix throughout. We don’t guarantee rankings, but we do everything we can.

Real work: 1,576 products moved from iGetWeb to WordPress

MCR Autoparts, an importer of genuine Porsche and supercar parts, had run on iGetWeb since 2015 when the provider announced it would close at year end.

Old product URLs mixed numeric IDs with Thai product names, which often get truncated or re-encoded when shared, so we matched redirects on the numeric ID only. Instead of putting 3,274 lines in .htaccess, the old IDs are stored with each product and category in the database and resolved through a cached lookup.

Platforms we migrate from

What can be exported depends on each platform and plan, so this is general guidance, not a per-platform promise. We check the real site during the audit.

Our migration process

Before migration

1. List every existing page. Crawl the whole site, combine with the old sitemap, Search Console, Ahrefs (pages with backlinks or traffic) and platform exports.
2. Record current keyword rankings and traffic so there is a baseline to compare after launch.
3. Identify the most important pages by traffic, backlinks and sales. These keep their content and titles and are checked by hand.
4. Plan the old URL → new URL mapping in a redirect-map spreadsheet: one row per old URL, matched on stable IDs, never dumping everything on the homepage, handling query strings, tags and empty categories.

During migration

1. 301-redirect every page correctly: one hop, permanent, landing on a 200 page.
2. Check titles, meta descriptions, canonicals, sitemap and robots.txt, plus structured data, hreflang for multilingual sites, image alt text and internal links.
3. Notify Google via Search Console: keep the verification token, submit the new sitemap. Change of Address applies only when the domain changes. Keep GA4 tracking and conversions continuous.
4. Check speed and mobile usability with Lighthouse and Core Web Vitals on staging.
5. Brief and QA the developers so the build follows the SEO plan, whether it’s our team or yours.

Launch and after

• Staging QA: noindex on staging, item counts against the old site, every redirect and sitemap URL tested.
• Launch-day checklist: backups, DNS, SSL/https, remove noindex, open robots.txt, verify canonicals, submit sitemap, check GA4.
• 30 / 60 / 90-day monitoring: new 404s, indexing, rankings and clicks against the baseline, with fixes as we go.

Frequently asked questions

Will I lose my Google rankings if I move to WordPress?

If every old URL is 301-redirected to the matching new page and titles, content, images and internal links come across intact, most ranking signals transfer to the new pages. Rankings can fluctuate for a few weeks while Google recrawls; we monitor and fix issues through that period. We don't guarantee rankings, but we do everything we can to protect them.

Can you migrate from iGetWeb, MakeWebEasy, Wix or ReadyPlanet?

Yes. We migrate from Thai and international website builders, e-commerce platforms, other CMSs and hand-coded sites. Where the platform has an export we use it; where it doesn't, we extract data from the live pages and count it against the original, as in our iGetWeb migration of 1,576 products.

Do I need to change my domain?

No, and we usually recommend keeping it. If a domain change is necessary, we redirect across domains and file a Change of Address in Google Search Console.

Does the old site go offline during the migration?

No. We build on a staging site blocked from Google. Your current site keeps running until switchover day.

Will all products, images and articles come across?

We count items before and after and compare. Some platform-locked data, such as customer passwords or some order histories, may not be portable; we tell you during the audit, before work starts.

How long does a migration take?

It depends on size and complexity. A small company site is quick; a shop with thousands of products takes weeks. Our 1,576-product parts store took about four weeks including a redesign.

Can you keep the same look and only change the system?

Yes. For large sites we often migrate like-for-like first and redesign afterwards, so if rankings move we know why.

What happens after launch?

We watch 404s, indexing and keyword positions in Search Console at 30, 60 and 90 days, fix any broken links immediately, and train your team to use WordPress.
