How to Switch Web Design Agencies Without Losing Your Website, Domain, or Search Rankings

The Short Answer

You can switch web design agencies without losing your website, domain, or search rankings as long as you keep control of your domain registration, get a full export of your current site before you leave, and use permanent (301) server-side redirects for any URL that changes during the rebuild. Google itself recommends keeping those redirects active for at least a year so ranking signals have time to transfer. The most common way contractors lose rankings during a switch is not the new design itself — it is URLs changing with no redirect in place.

Why Switching Web Design Agencies Feels Riskier Than It Is

Most contractors put off switching web design agencies long after they should have, not because the new agency is unclear about design, but because nobody is clear about what happens to the old site, its domain, and the rankings it already has. That uncertainty is usually worse than the actual risk — the risk is real, but it is also well documented and largely avoidable if you know what to check before the switch, not after.

The mistakes that actually cost contractors traffic are almost always the same handful of technical oversights, not bad decisions about who to hire next.

Who Actually Owns What: Domain, Hosting, and Content

Before you switch anyone, confirm three things in writing: who owns the domain registration (it should be you, under your own account, not your current agency’s), where the site is hosted and whether that account is yours or theirs, and whether you have a current backup or export of your site’s content and design files. If your current agency owns your domain registration under their own account, get that transferred to an account you control before you do anything else — this is the single most common way contractors get stuck paying an agency they no longer want to work with just to keep their own website address.

The Redirect Step Most Contractors Skip

If your new site keeps the same URLs as your old one, this step barely matters. If any URLs change — a new page structure, a new domain, or even just a different way of naming service pages — every old URL that had rankings, backlinks, or bookmarks pointing to it needs a permanent, server-side redirect to its new location. Google’s own site migration documentation is explicit that these should be actual server-side 301 or 308 redirects, not JavaScript or meta-refresh redirects, and that redirects should stay active for at least a year to give ranking signals time to fully transfer to the new URLs.

The most damaging version of this mistake is redirecting every old URL to your new homepage instead of to its actual equivalent page. Google flags this specifically as a common error, since it tells search engines the old, specific page and the new, generic homepage are the same thing, which they are not. Search Engine Land’s own site migration checklist lists this same mistake as one of the most frequent causes of a lasting traffic drop after a redesign.

A Realistic Timeline for the Switch

According to Google’s own guidance, a medium-sized website can take a few weeks or more for search results to fully shift from old URLs to new ones, and larger sites can take longer. That means a short-term dip in visibility during the transition is normal and expected, not a sign the switch failed. What is not normal is a dip that never recovers after a month or two — that usually means a redirect or indexing step was missed, not that switching agencies was a mistake.

A Pre-Switch Checklist for Switching Web Design Agencies

• Confirm you own your domain registration under an account only you control.
• Get a full export or backup of your current site’s content, images, and design files before access is revoked.
• Give your new agency your current site’s full URL list (a sitemap works) so they can map every old URL to its new equivalent.
• Confirm server-side 301 redirects will be used for every changed URL, not JavaScript redirects.
• Verify both the old and new site are set up in Google Search Console so you can monitor the transition.
• Keep the old hosting or domain-forwarding active for redirects to keep working, ideally for a full year.
• Ask your new agency directly how they plan to prevent a traffic or ranking dip, and expect a specific answer, not a general reassurance.

Should You Manage This Switch Yourself, or Have Your New Agency Handle It?

If your current site’s URLs are staying the same and only the design is changing, this is straightforward enough for most owners to manage with a checklist. If URLs are changing, the domain needs to move, or you are not fully sure who currently controls your hosting and domain, that is exactly the situation where a mishandled migration can cost you real search traffic — and where it is worth having your new web design agency run point on the technical handoff rather than doing it yourself. A competent agency should be willing to walk you through exactly how they handle redirects and rankings before you sign anything, using the checklist above as your starting questions.

For what a full contractor website redesign typically costs once you have found the right agency, see our website redesign pricing guide, and if you have not settled on a new agency yet, our guide to vetting a web design agency before you sign anything covers the questions to ask before you commit to anyone. Our website design service page also walks through how we personally handle a migration like this for a new client.

Frequently Asked Questions About Switching Web Design Agencies

Will I definitely lose some rankings when I switch agencies?

Not necessarily. A short-term fluctuation while Google re-crawls and re-indexes changed URLs is normal, but a lasting drop almost always traces back to a missing or broken redirect, not the switch itself.

How long should I keep old redirects active after switching?

At least one year, per Google’s own migration guidance, to give ranking signals full time to transfer from old URLs to new ones.

What if my current agency owns my domain and won’t cooperate?

This is exactly why confirming domain ownership should happen before you announce you are switching. If you do not currently control your own domain registration, that is the first thing to resolve, even before choosing a new agency.

Do I need to keep my old website’s content, or can I start completely fresh?

You can redesign completely, but keep a backup of the old content and URL structure regardless — your new agency needs the old URL list to build accurate redirects even if none of the actual content is reused. If you do decide to rewrite your pages from scratch, our guide on what to ask a website copywriter before you hire them covers the questions that separate a copywriter who understands contractor SEO from one who doesn’t.

How do I know if my new agency actually knows how to handle this correctly?

Ask them directly how they plan to handle redirects and ranking preservation before you sign anything, and expect a specific, confident answer using the language in this article — server-side redirects, URL mapping, Search Console monitoring — not a vague assurance that “we’ll take care of it.”
