Looking for a SEO plugin for Drupal
I thought the following was a bit like Yoast . SEO Compliance Checker - https://www.drupal.org/project/seo_checker

Once downloaded install and enable.

SEO Checklist

Basic SEO Modules

Keyword Rules

Then go to configuration .

Once those modules have been enabled you’ll then have a nice set of Sliders to use in the ‘Thresholds for the SEO Rules’ box.
Set up your sliders depending on what the recommended levels are at the time.
From here you’ll then need to visit the Article that you want to optimise .  


  Click on PREVIEW


The Keywords are taken from 'tags' .
