Pros: SEMRush is a full-fledged powerhouse for SEO building strategy and SEO audits. It's pretty beefy, so I would only recommend it if you have the time and patience for SEO, as the software gives a ton of outlets in looking up actionable items for your SEO Strategy. The first thing that I really liked with SEMRush was the initial SEO audit of my site -- I was able to see what's good and what's bad about my SEO, and the quick errors or warnings for title headers and ideas for gaining more traffic was awesome. Moving on, I found their analytics just as good as Google Analytics, showing me where my traffic is coming from and where I can improve my paid search positions. I haven't used the Social or Content aspects of SEMRush but social listening looks to be baked in well and integrated nicely. If you're in the market for seeing how your organic and paid search traffic plays a part, and then strategizing in how to improve your overall position against organic search and then your competitors, I'd recommend SEMRush.
Readability: The readability metric isn’t something new. However, the fact that gives you the opportunity to match your text’s readability to that of the top 10 competitors in the niche is interesting. A readability score of 56.4 is considered to be “fairly difficult,” to read and so the target is usually 60 and beyond if the niche requires it. For some texts, the readability should be more complex because that’s what the target audience expects and the tool makes that suggestion.
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.

If you are looking for keywords in languages other than English, you will find Keyword Tool's features very useful.

That way we make sure that the generated keywords will be relevant to the country and/or language that you are creating your content for.

Pros: SEMrush offers many ways for comprehensive competitve research. It is a must have for every search engine optimizer. Information handled is extensive and can be passed on to clients easily and for our team to use efficiently. SEMrush has a SEO community aspect, the training base and integration is excellent. Videos and webinars are offered for comprehension and awareness.
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.

I like the ability to compare a client’s website to it’s competition. This feature is awesome. Enables side by side comparisons on how you are doing vs competitors for key metrics such as back links, SERP Results, Domain Strength, etc. The information I can get on Organic Search, Paid Search and keywords is also extremely helpful to the work I do. Thanks Matthew for this article. I wish to win this :)
There are other parts of SEO which you should pay attention to after your audit to make sure you stay competitive. After all, the technical foundation isn't the end of the road for SEO success. It's important to pay attention to your competition's SEO activity, keep an eye on the newest search engine best practices, and maintain local SEO best practices if your business depends on customers visiting a physical address. All of these are elements of a successful SEO strategy and should be corollary to your audit and ongoing SEO maintenance. 

Another feature of Ahrefs that could potentially help you take your campaign to even better heights is their content gap feature. It gives you the option to check which keywords your competitors are ranking for so you can stay one step ahead at all times. Basically speaking, Ahrefs gives SEOs the ability to overtake their competitors through knowing which keywords to target and focus on.
SEMrush is an extremely popular SEO software which encompasses a host of tools for social media, website audits, rank tracking, etc. It is considered the gold standard when it comes to competitive analysis features. The features provide users with valuable information about their competition, link building, display advertising, organic search, and paid search. All that information allows you to see how well the competition is performing which in turn helps you decide which are the best strategies to use in your own SEO campaigns. Plus, it shows why some of the competition is doing poorly so that you can avoid what clearly isn’t working for them.
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!

Pros: SEMrush is our primary SEO tool and it really does it all, especially with the massive upgrades in the last year. It tracks keyword ranking positions, offers a few keyword research tools, and compares the domain to others related to it. You can automate reports that are white labeled, too. It also does domain analysis, backlink tracking, and site audits which we use all the time in our SEO business. They have recently rolled out link opportunity and outreach tools as well as brand monitoring on social media, though we haven't used those as much lately (but plan to).


SEOptimer is a free SEO Audit Tool that will perform a detailed SEO Analysis across 100 website data points, and provide clear and actionable recommendations for steps you can take to improve your online presence and ultimately rank better in Search Engine Results.

Now the Domain vs. Domain tool is a rather unusual visual tool which allows you to compare up to 5 different domains. You can then compare and contrast data from all of the domains. It is handy for SEO experts who want to conduct and later update their competitive analysis of the industry and where they fit in. The Venn algorithm uses diagrams and other essential bits of data to give you a pretty good idea of where your website is placed in the grand context of the niche.
