Hello.
My name is Palla Sridhar. from India. small time blogger.
I have a SEO site which recently had 12 pv/day.
I recently did 2 guest posts on 2 sites. On 1 site, I included link to my site's article in the content and author bio. In another I just did it in author bio. After that my traffic dropped to 4 pv/day.
Is there any official guide from Moz, on how to do link-building? Is the above process of doing link-building correct? How to do it without getting our traffic affected in the long run and short run?
