SEO plugins for WordPress are very useful,
but there are none that releases SEO traffic.
I explain why in a moment

– Either you have to be hyperactive on social networks and share everything.
– Either you have to use interwebs with advanced techniques to build your popularity

If you concentrate on external levers right away, it will take a lot of time. It’s a bit like wanting to build a 5-story house without having solid foundations.

The amount of effort to produce is enormous and you will not be able to climb very high.

The effects of levers obtained are very low because only a few targeted pages take advantage of the visibility created.
