Google’s has done changes to algorithm to boost rankings of mobile friendly sites. The search engine has decided to improve their search visibility long ago and was pending update. These was google’s part of strategy to improve search experience with mobile devices. This was due to increase in mobile users in last 5 years.
It was to be believed that this will only have effect on mobile search and you can experience with mobile devices only. Today it’s been reported that many informational sites like “Hubpages” having more than 870,000 blogs and covers almost all topics on web. All blogs on hub pages are written by writers & bloggers and contains very good information about different topics. Average blog on hubpages is more than 400 words and well formatted for readers and search engines. Hubs pages has very good search ratio on web but it is reported by Paul Edmondson (CEO) that traffic is down by 22% on 3rd of May from previous week.
Looks like Google’s this Algo tweak is more on “Mobile” but also has effect on various other sites like “hubpages” who provides “informational” or “ how to content”.
Google has not provided any information or not commented till date about such types of changes.
