K-meta is a tool for in-depth analysis of organic and paid marketing strategies of your competitors. It allows you to use keywords data from 27 countries with all crucial metrics: Cost per click, Search volume, Competition.

If inclined towards knowing more about competition, then Ahrefs. It's data-driven (much more than SEO) - they crawl 6 billion pages every day and you can learn almost everything about your competitors. It helps to know where your competition is getting traffic from, exact keywords they use, how much traffic it brings them and how many backlinks & who exactly links to their website. You can also set “Alerts” for website rankings or mentions.

It is the fastest way to boost your Google rankings. Last year, we realized that the competition in Google was made up of mega-brands like Wikipedia, Forbes and Entrepreneur. And to have a puncher’s chance against these huge authority sites we need to outsmart them. We had started to experiment with some advanced theories about how Google classifies top ranking content and put them into practice. And the results were incredible: * Higher rankings; * More organic traffic (within days). For example, Jason Acidre from Kaiserthesage improved his organic traffic by 157.80% using this tool: “*I’ve first started using it on the 2nd of June 2017, on 15 web pages. I saw massive improvements in traffic and rankings for most of the test pages I’ve optimized with the tool in 2 weeks after the changes have been made. It only took me around 5-10 mins to re-optimize a single page!*” The Keyword Tool & Content Assistant uses artificial intelligence to understand how content impacts search engines’ rankings. A lot of Google reverse engineering was involved in this, combining algorithms and concepts such as semantic search, LSI (Latent Semantic Indexing), TF*IDF or topical authority, just to mention a few. To put it to the test, we ran a research on 30.000 keywords that shows a clear correlation between the Content Performance Score and the position in Google. For a more detailed overview on the ins-and-outs of the tool, we’ve published a dedicated launch article on our blog: https://cognitiveseo.com/blog/14...

It saves time every single day for SEO people. Either you are checking keyword ranking on SERP or researching about new topic you know where your competitors are on the same page. It's quick and easy.
