This argues against my own product, so let me say it plainly
If you have no Google Business Profile and a limited budget, do not buy a website from me yet. Claim the profile, it is free. Ask your last ten happy customers for a review. Then come back and talk about a site. That order will make you more money than the reverse, and anyone who tells you otherwise is selling.
I set the profile up with every website I build, and if the profile is genuinely all you need, I will tell you that and you can do it yourself with the steps below. It costs nothing to claim.
