Hi Oleg
With the apparent reason emphasis on social shares likes and links been possibly a more accurate we are determining for the search engines whether content is popular and focusing on this we already have lots of content on the websites. I have initially posted introduction link to each post on our website copy and pasted into to our twitter, FB.and GP accounts with the same link, but the decided that in short bursts I will do unique introductions to the links. Looking at my competition which is above me in the search engine results they tend to be much larger companies and are not focusing very much on social media so will see if the results pay any dividends all the best Alan
I'll give you an update for your interest in the future
