Guest blogging is a term that needs no introduction , still for the newbies - guest blogging means writing articles for other blogs in return for backlinks (some even share adsense revenue) to leverage your own blog , it is different from article submission ,mind you . Have you actively used guest blogging ? I have been using guest blogging extensively and it has worked wonders for my blog . I was wondering that most of the guest blogging sites allow 2 links in author bio . So instead of using the 2 links as your own domain (even if its homepage and deeplink) why not use another link , like of a mutual benefit friend ? Yes you got me right . Say you are into guest blogging then you can include one link of your domain and another of mine and I will do the same when I guest blog on another site so both of us will ultimately end up getting links from 2 high PR domains instead of 2 links from the same domain which is useless practically . Hit me up in the comments section and lets see how many of us end up helping each other leverage their sites with guest blogging .
