I just got done scraping all my competitors back links using ScrapeBox and have them all saved in a folder and separated by platform (wordpress, drupal, Movable Type, etc). I have three different long tail keywords that I plan on using with the Commenter. How many times should I comment on these blogs I scraped using the same set of keywords? If it's fine to comment on this blogs using the same set of keywords how often should it be done? If it's not good practice to comment on these blog using the same set of keywords more then once, would it be fine to go back and comment on them using a different set of keywords that link to other pages on my site? Final question, am I on the right track here or should I be doing something totally different??
