The king of SEO plugins. Yoast was launched in 2010 and very quickly established itself and the most popular SEO plugin for WordPress. In fact, for many years it was pretty much the default SEO plugin for many sites, the competition was simply not good enough, and didn’t get a look in. Besides being a hugely popular SEO plugin, it is just in general one of the most popular plugins, hands down, with over 200 million downloads and over 5 million active installs. Yoast has reined king for a long time, but is now time for a new king to emerge?
