For my Adsense plugin which you can get here https://wordpress.org/plugins/adsense-made-easy-best-simple-ad-inserter/ I’ve created a PRO version (https://www.seo101.net/adsense-made-easy-pro/) that is available to those that sign up for my mailing list. It’s not much but it gets me 5 to 6 subscibers a day. And best of all I know exactly what my subscribers are interested in… WordPress and Adsense:)
Fortunately, Google puts more weight on the anchor text of external links anyway. So as long as some of your external links have your target anchors, you’re probably OK with a “Home” button. In fact, I’ve ranked homepages with a “Home” anchor text nav button for some seriously competitive terms. So it’s not a make-or-break ranking signal by any means.
