When Joost de Valk, founder of Yoast, apologized for the bug that caused some websites to drop significantly in the search engine results pages, you could hear a collective sigh of relief from effected webmasters. Since Yoast is supposed to help WordPress users rank higher in the SERPS, webmasters didn't expect that the latest version of the plugin was causing the problem immediately. They attributed their drop in rankings to negative SEO, an erroneous Google penalty and a variety of other causes. With million of users, Yoast, both the freemium and paid versions, is one of the most popular WordPress plugins ever. Both Forbes and GoDaddy have recommended Yoast, which is why users were not expecting the problem came from the plugin's latest 7.0 update. Yoast users who dropped in the rankings since March 5 should check their Yoast SEO Media Plugin settings to access the Media & attachment URLs setting, which the bug caused to default to no instead of the recommended yes. There is also a Yoast SEO Search Index Purge Plugin to download. Joost de Valk's apology for the bug was sincere. He admitted to creating the code himself, "I myself, am sorry. More so than normal, because I came up with and coded this change myself." Nevertheless, people who paid $80 for the premium version were upset at losing business. Yoast premium users gladly pay for the SEO plugin because their blog is their livelihood. Moving down in the rankings, even for a few days, has a significant effect on their income. People still consider Yoast the best freemium WordPress plugin available. The premium version adds extra functionality, however, the free plugin contains the important functions. Setting up the plugin can seem overwhelming to users new at SEO; there are numerous tutorials available online from Yoast and from third parties.
