What needs to be decided before the merger?
Capture a side-by-side inventory of both businesses before anyone changes URLs, listings or tracking.

A sale where the same customer-facing shop continues is covered in what happens to Google Business Profile when a business is sold. A name change on one continuing entity is how a business can rebrand without losing Local SEO visibility.
Which brand survives?
That is a business and legal decision. SEO consequences follow whichever identity customers will actually use.
This page does not choose your brand. If both names remain as genuine locations or departments, representation rules still apply. If one name is retired, treat public pages and profiles as a rebrand or closure of that identity, not as two living brands.
What happens to the two domains?
Decide which hostname is canonical for the surviving organisation, then map URLs. Merging domains is a site move.
Google’s site-move documentation covers changing domains and merging multiple domains or hostnames. Prepare the new site, map old URLs to new ones, redirect, then monitor both properties in Search Console. Verify all variants (www/non-www, HTTP/HTTPS) of old and new. There is no fixed crawl frequency; Google says medium-sized sites can take a few weeks or more, and larger sites longer. Source: How to move a site.
Should one website redirect to the other?
Often yes for a retired domain, but it requires URL-by-URL mapping where relevant rather than a blanket homepage redirect.
Strong service and location pages should point at their equivalents. Google’s move guide tells you to start with important URLs from sitemaps, analytics and links. A single wildcard to the new homepage discards that work.
What should happen to strong pages from both websites?
Map intent and value. Keep the better URL for each job, merge unique facts, and redirect the rest to that equivalent.
Two “emergency plumber” pages should not both stay live as near-duplicates. Two genuine clinic pages at different addresses should both stay if both sites remain open.
What happens to the Business Profiles?
Do not automatically merge profiles. Separate eligible locations can remain separate listings under the surviving business.
Google’s duplicate help describes merging when two or more profiles represent the same business. That is not a tool for combining two different addresses into one pin. If a location closes as part of the merger, mark that listing permanently closed. If ownership of a continuing location changes, transfer primary ownership. If the public name changes on a continuing listing, follow current rebrand rules. Sources: Resolve duplicate profiles and ownership issues, Transfer primary ownership of a Business Profile and Mark your business as closed.
What about reviews?
Do not promise that reviews will transfer from one company’s listing onto another company’s listing.
Google says transferring primary ownership of a continuing Business Profile maintains information like reviews, and that merging duplicate profiles of the same business combines reviews (replies may be lost). Neither statement is a guarantee that two different businesses’ review histories can be stacked onto one pin. Source: Transfer primary ownership of a Business Profile.
What happens to citations?
Update high-impact listings to the surviving name, address, phone and URL once those facts are stable.
Closed locations should be marked closed in directories that still send walk-ins. Do not leave two live NAP sets for one remaining shop. See inconsistent business information online.
What happens to Search Console?
Verify the surviving properties, keep history on the old properties while redirects run, and use Change of Address only when Google’s tool applies to your type of move.
Google’s move guide says to verify old and new sites, review settings, and be patient. The Change of Address tool is for domain moves that meet its requirements; it does not replace redirects. Source: How to move a site.
What happens to Analytics and GTM?
Place GA4 and Tag Manager under the surviving organisation. Decide whether you need a new GA4 property for clean reporting or can keep one property with a documented cutover date.
Google’s site-move notes say that if you use Google Analytics, consider a new profile if you want clean separation in content reports. Either choice is a measurement design, not a ranking requirement. Keep GTM administered inside the organisation. Source: How to move a site.
Should brand + domain + CMS + page structure all change on the same day?
Avoid stacking every major change on one launch when you can sequence them.
Google currently says: change only one thing at a time. Plan changes one after the other, not everything at the same time. The example given is moving to a new domain, then changing CMS, then updating layout — not all at once. A merger often forces several facts to change; still separate domain cutover from a full redesign where you can, so a drop can be diagnosed. Source: How to move a site.

Do not assume reviews move between different businesses. Do not assume two remaining shops should become one Maps pin. Do not assume Google will finish recrawling on a timetable you can put in a press release.
What not to do
Practical action plan
- Complete the inventory table with owners in the room.
- Lock the surviving brand, domain and location list in writing.
- Map URLs; prepare redirects; verify Search Console on both sides.
- Transfer or close Business Profiles according to whether each site continues.
- Update citations and tracking after the public facts are stable.
- Monitor old and new URLs; expect temporary ranking fluctuation during recrawl.
When professional help makes sense
Help is useful when both sites have strong pages, mixed listings and overlapping service areas. A merger migration is not guaranteed to preserve visibility.
