Social media .... signals to the search engines that your content is valuable for those seeking
Social media does not signal to the search engines - they signal to people that content is valuable. This in turn can generate rare links that signals to the search engines. There is a difference.
As a second point the author claims that content marketing is increasingly gaining ground . This started out as a strong trend in 2013 and is believed to be continued to strength this year. At this point I am inclined to agree . In short , it's about having a relevant and content rich content on the page. Something that both attracts visitors and Google in the long run.The third point was that the optimization for mobile devices is a must for anyone wanting to keep up with developments . The author mainly points to is that we use mobiles increasingly while the development of Google makes responses more accurate based on what we type into the search field.This is something that should be taken into account when optimizing . Maybe he / she is right in this , maybe not. The pages to be adapted for mobile is easy to agree with , but the searches done differently between whether they occur on the cell phone or on your computer? Used longer phrases if one is looking through the computer and it's different things you are looking for through the various equipment ?If so, is this something you should investigate further . If you have a page that is mostly frequented by visitors with mobile devices would then long tails be something you lesser degree would be working with . Maybe he/she is right - maybe not.
Social media is important but ..
The fourth point is that social media is becoming increasingly important. It is possible to agree but as previously said not to get the link power without getting the interest of the customer. But the author argues that Google is increasingly going on human signals, and hence must invest heavily in social media to get a good result in their SEO strategy.
It may be that the author has the exact same opinion as me but then chooses his / her words slightly wrong. For there is a difference between SEO and classical marketing. Although they go hand in hand sometimes, you have to distinguish between them in some cases to get the best results on Serpen.
