This is the SEO (Search Engine Optimisation) and Social Media part of the Stats section on your Admin Dashboard. On this page, you can see the number of unique visitors from search engines and social media, top search keywords, top referrers, search engines used and top social networks.
If you hover over the titles of the results sections, a description box will appear to inform you of that title's meaning. For example, ‘Top Referrers’ – Full list of referrals which have resulted in a visit to your website.
These results are displayed in graphs, tables and pie charts and can be changed according to the date range. To change the date range, simply use the date range boxes at the top right-hand side of the page, click on the dates that you want using the calendars and to save, click on the blue 'Apply' button.
