Keyword explorer, which was released few weeks back is one of the most exhaustive tools that we have see off late. Keyword Ideas, Phrase Match and KD help content marketers to align their content marketing efforts with organic search trends. Apart from that from an on page point of view, the tool gives everything that modern age webmaster need to track their overall performance.
Detailed breakdown of all our key SEO metrics and performance history. It's very easy to compare our performance against competitors, and identify new opportunities to improve. The "link intersect" tool is amazing! You can easily see who's linking to your competitors and not your site, and work through the report list to build your presence on those domains.
Ahrefs boasts the best link database among any system out there. It does most everything -- link monitoring, alerts, calculated metrics, the richest clickstream blend out there, and much more. Its UI is cluttered in a good way and the company has quick and polite support. And Tim Soulo -- the public face of Ahrefs -- has done a ton of good for the SEO community.
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.
