One of the changes announced in February’s Panda 3.3 update began to show its effects last week.
Earlier this year Google announced that they were now taking social media signals into consideration in their ranking algorithm, so now the ‘number of Tweets’ will play a part in how your website is ranked on Google. There is also a correlation between Facebook likes and high rankings although Google doesn’t directly use this data.
If you haven’t already heard, Google have recently released their +1 button. The idea is pretty simple and works in a similar way to the ‘like’ button on Facebook. It is a way of letting other Google users know what you think is cool, interesting or helpful.
