FAQ

How long does a migration impact rankings?

Even with a perfect migration, you may see 2-4 weeks of "Search Volatility" as Google re-crawls your site. Most sites recover fully or exceed their old rankings within 6-8 weeks if the technical foundation is improved (see Serverless Architecture in 2025: Why Scaling is No Longer Your Problem).

Can I migrate my site without an agency?

For small sites (<50 pages), a careful manual migration is possible. For e-commerce or enterprise sites, the risk of data loss and ranking drops is too high. We recommend our Premier Services for these complex projects.

Is it a good idea to change my domain?

Only if necessary for branding. Domain changes carry the highest risk since you are essentially starting a new relationship with Google. If you must do it, follow our International SEO Guide 2025: Scaling Your Organic Reach Globally and migration protocols to the letter.

What is the most common migration mistake?

Failing to map old "Secondary" pages. Brands often migrate their top 10 pages but forget the hundreds of The Semantic SEO Guide for 2025: Moving from Keywords to Entities support articles that provide the "Topical Authority" for the main pages.

Does "Headless" make migration easier?

Yes! Because the content is managed separately in a The Benefits of Headless CMS in 2025: Uncoupling for High-Performance Growth, you can redesign the frontend (the "head") without risking the integrity of your core content and The Ultimate Technical SEO Audit Guide for 2025: Fix Your Foundation data.
