Promotion of the site

The site was advanced from almost zero. The Joomla 2.
The promotion period was directed by me from October to December 2015.
Furthermore, I noticed the site's filling with content, but according to Google Analytics, the actions on the site were carried out through the pages filled with my SEO text and on those pages to which I left external links.
Internal optimization has been made:
Rescue from the dupes
Selection of the semantic core
Installation of sitemap.xml and robots.txt
Order of text and their independent composition
- improving the userability of the site (Error 404, feature to view similar items, button back up)
The external optimization:
Free external links
The number of organic traffic has increased:
- October 2015 - 218 benefits/month
- December 2015 - 922 benefits/month
- January 2016 - 4743 Poles/month
Promotion of NC and SC requests in TOP-3
