Just another question about ScrapeBox

So I've been using scrapebox for sometime now, but i find that the harvest feature is not very accurate at all, for example.

If I search for all the wordpress blogs for keyword

"hp laptops"

I ended up with 40% of the sites that's totally unrelated to "laptops".

As I usually put in comments like this

"I really like your article about hp laptop, I personally own one as well...."

into sites that's not related to laptops at all, how do I solve this problem?

Should I get more genetic comments like "I really like this article, it's brilliant"??

Thanks for your advice.

Thanks gamecity, I am going to try that
