SEO link backs

First question... If I have posted links of my site on blogs, forums... do I need to link to them on my site too?

Second... is scrapebox is good to do the auto posting? is it not spam?

thanks

 

You dont need to be linking back to forums or blogs......not unless they are requesting you too.

 

Never link back (if you can help it!). Reciprocal linking will do nothing for you these days.

 

There is no need to give link back in return of forums, blogs and other links,..........
