If you shove every service onto one page on your website instead of having a dedicated page for each, AI and Google are both confused about what you do. If your name and number are different on every different site, instead of matching up everywhere, it could just be the name spelt with two words or one numbers wrong. AI and Google might not be sure that you're real.
If you ask for a review just once a year instead of every job or every purchase, you are going to lack proof.
If your about page is just some paragraph from chat, t instead of your real name, face and authorship, AI is not gonna trust you enough to show you in its answers. If you want more AI search education, follow me.
