Hi

Opensiteexplorer is not bad but I have to say that ahrefs is more comprehensive. I would recommend ahrefs even though sometimes it misses important links with high DA.there is also a problem with delays at it will only catch some links today when those exists since 2 years or more. So be very careful when analyzing links with any tool, they often lack precision.

Cheers

Hi

I agree with Lesley. there is a whole hypocrisy around this matter. I have had the opportunity to purchase articles related to our website from so many Bloggers, even for the biggest blogs such as Techcrunch, Mashable, Forbes... it seems that everything has a price nowadays and that a lot of your competitors might already be using these techniques.

I think that if the blog and the article are relevant, you should consider it.
