Hi Anil, a fantastic post. I would like to know your opinion since in my case I do not have the budget to keep two tools at the same time. I currently use semrush since there are things that I like a lot but I have doubts about the speed of the backlink audit tool. Recently I have encountered a problem in which semrush has not detected backlinks that were potentially dangerous to my website and this has hurt me. This part worries me a little because I’ve already seen the ears of the wolf. On the price-quality ratio of the two tools, would you continue with semrush or would you go to ahrefs? Thank you very much!
Have you ever received a warning from Google Chrome to not visit a page? It will block the page and prevent you from going there because of some security issue. We begin by ensuring your website passes a SSL Certificate Validity Check. This a whole range of security protocols that should be within your website’s coding or built-in to the domain. It shows the world that your site is trustworthy!
Like all backlink monitors, it doesn't pick up anywhere near all backlinks and is slow to pick up new backlinks. However, all backlink tools have this same problem and Ahrefs is the best of those tools. One of my biggest gripes is that Ahrefs drops backlinks and count them as a lost domain, but after looking into the dropped campaigns you find that a majority of them are still there and Ahrefs dropped them from your backlink profile for an unknown reason.
The total number of backlinks and their quality pointing to your complete website result in the overall authority of your domain. The external links that all point to a specific page will help this page to rank in the search engine results (SERPs). The relevance and quality of an external link are very important factors when you like to measure the impact / value of an link. To find out more about quality links have a look at this article on: the Official Google Webmaster Central Blog – https://webmasters.googleblog.com/2010/06/quality-links-to-your-site.html
Ahrefs also helps users dig deep into their competitors’ search traffic with the Positions Explorer tool. You can easily see the keywords the competition is ranking for in the search engines as well as the keywords they are spending on for their advertising and marketing campaigns. Even better, you can see the flow of organic and paid traffic they are receiving.
Do you know that there are millions of people that are searching for something on YouTube every single day? Fortunately, YouTube is trying to make it easier for people to find what they are looking for. Which is why every time you make a search on YouTube, you will see a list of suggested terms as you start typing your search query. Usually, the most popular and relevant YouTube searches show up in these suggestions.
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.

Basically, Google shows the autocomplete suggestions whenever you start typing anything into Google search box. It is in Google's best interest to show the most relevant keywords in the autocomplete suggestions. Keywords that would help Google to retrieve the most relevant websites and help users find the most relevant content for their search query.
The depth of your articles impresses and amazes me. I love all the specific examples and tool recommendations. You discuss the importance of backlinks. How important is it to use a tool to list you on directories (Yext, Moz Local, Synup or JJUMP)? Will Google penalize you for listing on unimportant directories? Is it better to avoid these tools and get backlinks one at a time and avoid all but a few key directories?

AHREFS is certainly a great tool for bloggers and internet marketers. You have explained every functionality in great detail. I liked the link intersection part. It provides ou with a great opportunity to get backlinks from sites which are usually linking to your competitors. Further, its adds to the fact that these types of backlinks would be easier to get as compared to the ones that we search manually for any website. Plus, these would be niche specific too!
