How much does an SEO company charge for migration services?
There is no standard figure: SEO support for a migration is priced as a project, and the quote depends on how many URLs move, what kind of move it is, how many changes happen at once, and how long the company watches the site afterwards. The only number worth relying on is a written quote based on a review of your site, listing the URL count and the tasks it covers. What you are paying for is not the move itself, which your developers or host carry out, but the planning, mapping, and checking that protect your search traffic through it.
What the fee covers
The SEO side of a migration includes a crawl and inventory of every current URL, a map from each old URL to its new one, a review of titles, descriptions, structured data, and internal links on the new site, checks that analytics and Search Console keep recording correctly, testing before launch, and monitoring after it. A quote should say which of these are included and which are left to your developers.
What moves the price
The number of URLs is the first driver, and Google’s guide to moving a site with URL changes explains why the work grows with it: “The more pages that you move, the more likely you’ll encounter additional problems to solve.” Every URL needs a destination in the map and a check after launch, so a site with thousands of pages costs more than one with a few dozen.
The type of move matters next: a change of host with the same URLs is a smaller job than a new domain, a move to HTTPS, a new URL structure, or several sites merged into one. When a project combines changes, the guide recommends doing them one at a time: “Plan your changes to your site one after the other, not everything at the same time.” Spreading a domain change, a new content system, and a redesign over separate steps can mean more phases to pay for, but each phase is easier to check, and a problem can be traced to the change that caused it.
Large sites may also be moved in phases, and the guide suggests a trial run: “If your site is large and it’s technically possible, we recommend initially moving just a piece of the site to test any effects on traffic and search indexing.” A quote may price that trial section separately.
Monitoring after launch adds to the cost, because the guide states: “To consider a site move complete, Googlebot will have to visit every URL on your old and new site at least once.” How long that takes depends on the size of the site and how fast it can be crawled, so the monitoring period, and its cost, grows with the site.
How quotes are structured
Expect a fixed fee for a defined scope, sometimes divided into phases: planning and mapping, launch support, and monitoring after launch, each priced on its own. A clear proposal states the number of URLs covered, what happens to the price if that number changes, who builds and installs the redirects, what testing is done before and after launch, how long monitoring lasts, and what is excluded, such as rewriting content or design work.
Comparing quotes
Put the quotes side by side on those terms. A low quote with no URL count, no redirect map, and no monitoring period may simply leave out the work that protects your traffic, and a vague scope is where later change orders come from. A higher quote that lists each task can be the cheaper choice once the risk of losing traffic is counted.
