It does not matter what CMS you use. The important thing is to optimize the structure and content of the website. You can use Semalt AutoSEO and FullSEO to increase the visibility level. These packages help you to take any website to Google search TOP.
SEOs say that wordpress is the best – simple optimization
I work with Joomla and don’t have any problems. With autoSEO the positions increased in just a couple of months while I didn’t observe any progress during six preceding months.
Who cares? Professional optimization is above all. Semalt SEOs know their beans.
Drupal is very simple and convenient CMS. Speaking about SEO, it depends on the techniques you use. CMS does not matter for AutoSEO. It is external optimization.
