I consistently see the top 10 results for some pretty big keywords where all the sites have absolutely not one single exact match anchor text link according to ahrefs. Yes they could be blocking the ahrefs bot, (though they have to do it on the money site and the site the link is coming from, otherwise that doesn't work and ahrefs can still see links if the block is only one-sided) but it's highly unlikely as I'm seeing it in a wide variety of niches. Here's two big keywords for you as an example: 1. SEO New York 2. SEO New Orleans Every site in the top 10 results for these two keywords has 0% exact match anchor text density for those keywords. Pretty surprising right? Just goes to show you that you don't need exact match links anymore to rank. Partial match, generic anchor text and naked links do just fine. There's also nothing better than knowing you're ranking in 1st place without any exact match anchors behind you.
