If you have to choose for blog commenting, what would you do and what has the most impact?
I've bought a few different types of ScrapeBox blasts in the past, even though I own it, as I always tend to stumble slightly with finding high PR AND relevant sites for my niche. It's always either one or the other. In many cases, I'll go for relevance as why would a nuclear physicist forum (.edu) have in any common for my health related site?
Also, from the paid-for-blasts I have links from PR1-3 sites but that are an exact relevant match, although there are some high PR non-relevant ones there too.
What is best? What works? Or is having a mix of both good? If so, why?
