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:)
Great post. I know most of the stuff experienced people read and think “I know that already”… but actually lots of things we tend to forget even though we know them. So its always good to read those. What I liked most was the broken link solution. Not only to create a substitute for the broken link but actually going beyond that. I know some people do this as SEO technique but its actually also useful for the internet as you repair those broken links that others find somewhere else.
