AI-built sites can point Google at the wrong web address
A single line of leftover code can tell Google to index a page nobody can visit.
If you built or rebuilt your website with an AI tool, there is one line of code worth checking before you do anything else.
The SEO Guy (@theseoguy_) warns that sites built with AI often go live with their canonical tags still pointing at the staging domain rather than the real one. A canonical tag is a line of code in a page that tells Google which web address is the official version of that page. A staging domain is the temporary practice copy of a site, the version you build and test on before it goes live.
When the tag still names the staging address, you are telling Google that the real page lives somewhere your customers never go. As @theseoguy_ puts it, you "tell Google to index the wrong page and you won't rank".
What the tag is supposed to say
In normal use, each page carries a canonical tag that names itself, on your live domain. That is what self referencing means. Your about page says the official version of the about page is your live about page, and Google files it under that address.
The problem with AI site builders is that the tag gets written once, during the build, while the site still lives at the temporary address. Nothing visually breaks when you launch. The pages look right in a browser. The instruction buried in the code just keeps pointing backwards.
How to check yours
Open your homepage in a desktop browser, right click and choose view page source, then use your browser's find function to search for the word canonical. You are looking for a line with rel="canonical" and a web address next to it. That address should be your live domain, the one customers type in. If it shows a staging address, a preview address from your website builder, or anything that is not your real site, that is the fault.
Repeat the check on two or three other pages, because the tag is set per page and the homepage being correct does not guarantee the rest are. If you find the wrong address, the fix belongs with whoever built the site or with your website platform's settings, not with your writing or your keywords.
This is one SEO's warning rather than anything Google has announced, and the source does not say how common the problem is. But the check costs about two minutes, and the consequence of missing it is that pages you worked on simply do not rank. Worth doing today if your site is newly built.
make sure the canonicals are self referencing to your live domain
or you tell Google to index the wrong page and you won’t rank
