The tool is quite easy to use and it does pretty much what you expect it to. If you are into link research you should give this tool a try.

I've used a couple of SEO software programs over the last 4 years. Moz, Serpstat, SEM Rush and now Ahrefs. Since the bulk of my focus is actually building links, I think Ahrefs has the most reliable results. For example, if you checked the backlink profile of 10-20 websites on Ahrefs and compared to another SEO software provider, I bet that you would average at least 10-15% more results with Ahrefs. That can be a lot more opportunities! Their keyword phrase tracker seems to work pretty quickly and seems to be accurate.
Ahrefs is incredibly comprehensive and straight forward. From keyword discovery to site audits I use ahrefs for all my SEO needs. It's the first SEO program I was introduced to when starting me SEM management career and has proven to be the best time and time again. I've used their competitors liker moz, SEM rush, and a couple other services- none of which have come close to stacking up.
The thing that I liked the best about Ahrefs is that it contains a huge database of backlinks when I've checked my own website and my competitor's websites. This has allowed me to dig deeper and find out their exact linkbuilding and SEO strategies. Ahref contains a lot of tools and features that will make the life of an SEO professional or webmaster who wants more search engine traffic a lot easier. One of these features is the batch analysis feature. Basically, instead of entering your competitor's backlinks one at a time you could actually enter it once. This allows you to quickly check on the SEO metrics for a lot of competitor URLs in just one click.
