I just started up my website for buying t-shirts online and created a facebook page. I know facebook is good for traffic, but how can I influence SERPS with the page? Thank you!
You can put your targeted keyword into the description in a FB page (not FB profile). And you acquire high quality backlinks to the FB page. This can increase SERP at Google for a keyword that you want to rank.
i think this some times will make the facebook page ranking before your site, this is because facebook got high pr than your site.
Facebook post do not earn facebook page rank juice. However, one link on a certain facebook page can be profitable if thousand or millions followers see the link and share it on their facebook wall. In conclusion, facebook probably wont directly effect your SERP but indeed it has potential to effect your profit.
