Switching host, redesigning your site or changing your domain name is part of the normal life of a web project. But these operations often frighten people, and with reason: a badly prepared migration can sink years of SEO in a few hours. The good news is that a well-handled WordPress migration loses neither rankings nor traffic. It all comes down to method. Here is the procedure for changing course without sending your SEO overboard.
Preparing the migration ahead of time
A successful migration is decided before the first file is transferred. Start by taking an inventory of what exists. List your pages, their current URLs and their positions in the search results. Identify your high-traffic pages and the content that brings in conversions: those are the ones to protect first.
Use the opportunity to sort things out: our review of essential WordPress plugins and the ones to steer clear of saves you from carrying dead weight over to the new server.
Then define what is really changing. A simple change of host with no change to the URLs is the easiest operation. A redesign that alters the structure of the addresses, on the other hand, demands a rigorous redirect plan. The more precisely you map the before and the after, the less you risk nasty surprises. Pick a low-traffic moment for the switchover too, to limit the impact on your visitors.
A full backup: the safety net
Before touching anything, take a complete backup of your site. That means all the files, the theme, the plugins, the media, and the database that holds all your content and settings. This backup is your lifebuoy: if a step goes wrong, it lets you go back without damage.
Keep that copy somewhere safe, separate from the server you are migrating. Check that it is complete and usable before going any further. A backup that has never been tested offers only the illusion of safety. This simple precaution separates a calm migration from a high-risk operation.
301 redirects: the heart of the manoeuvre
If your URLs change, 301 redirects are the element that saves your SEO. A 301 redirect tells Google that a page has permanently moved to a new address, and transfers the authority the old page had earned across to it. Without those redirects, your old URLs return 404 errors, your visitors fall into the void and your SEO founders.
Draw up a redirect plan that pairs every old URL with its new destination, the closest possible in content. Avoid redirect chains, which dilute authority and slow down loading. Once in place, test every important redirect to confirm it points to the right page. It is the most technical step, and the one that tolerates no approximation.
Post-migration checks
Once the site has switched over, the work is not finished. Go through the sensitive points in order. First check that the site displays correctly on the main pages, on desktop as on mobile. Then check that internal links work and that images load.

On the SEO side, submit your new sitemap in Search Console and request indexing of the key pages. Make sure the title tags and meta descriptions have come across, and that the robots file is not blocking crawling of the site by mistake. A classic oversight: the setting that asks search engines not to index the site, sometimes used during the development phase, is left switched on. Check that point first.
Keeping watch on your SEO afterwards
A migration produces its effects over several weeks. Keep a close eye on your indicators for at least a month. In Search Console, watch the crawl errors, the progress of indexing and any not-found pages that surface. A slight drift in rankings right after the migration is normal, while Google recrawls the whole site.
If you see a lasting drop in traffic on a specific page, work back up the chain: check its redirect, its content and its indexing. Most post-migration drops come down to a missing redirect or a page that stayed blocked. Regular monitoring lets you correct fast, before the problem sets in.
Migrating with peace of mind
A WordPress migration is nothing like a leap into the unknown when it is prepared methodically. Inventory beforehand, full backup, careful 301 redirects, rigorous checks and monitoring over time: these five waypoints protect the whole of your SEO. Well run, the operation happens with no visible interruption for your visitors and no loss to your visibility.
