Checking a website’s on-page health is indispensable to making and keeping a website SEO- and user-friendly. Whether you manage a small website or a large one composed of thousands of webpages, detection of issues can be challenging. You just cannot afford to spend days looking for every possible mistake in the code or checking for broken images or URLs.
Its interesting that you overlooked Ahrefs site audit tool. Unlike SEMRush which limits you to 20,000 URLs, Ahrefs can crawl very large websites. Their data explorer is by far the best in the business. SEMRush gives you a list of URLs with issues they want to identify. But no option to customize. Ahrefs, much easier to use and powerful Data Explorer are very powerful indeed.

Competitor backlink audit – Analyse the link profile of your competitor and research the opportunities, to match your, or even better outperform your competitors link profile and subject authority. When performing an competitor backlink audit you should also analyse inbound links pointing to top performing pages, so you don’t miss out on valuable link opportunities.

You can schedule a weekly technical SEO audit and our Site Audit tool will automatically start crawling your website. You’ll get a notification when it is finished in your inbox. By running website SEO audits on a regular basis, you are tracking the progress of your website’s health. With the Compare Crawls and History reports, and mini-trends on the Overview, Issues, and Page reports, you can analyze the results of different SEO audits and track changes in the number of issues over time.
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.

As a professional blogger, I've always struggled with getting more traffic to my own websites and the websites that I handle. And one of the strategies that I routinely use is search engine optimization. SEO or Search engine optimization involves a lot of things. While On Page SEO is mostly done on the website, the OFF Page stuff is mostly done outside of your website. Ahrefs has helped me do a lot of the Off page stuff like analyzing what are my competitor's SEO strategies, what are their backlinks, where are they getting them. I've also used Ahrefs to find out my competitor's content strategy because I could easily check what are the content and pages that are getting the most shares and backlinks on their website.

Utilize the "broken backlink" section. Utilize the ability to isolate lost and gained links by date. Let's say you have drops around October. You could go to right before that and specifically isolate good links lost or bad links gained, etc. They also have a good amount of helpful online resources for learning how to use the tool. Great graphs show overall trends for linking domains or linking pages. Check out the ability to sort by AHREFS' quality statistics to help analyze quality/low quality links.
Great article. Before reading this I was practically sold on SEMrush. However, after reading this article and the comments from other readers, I’m realizing I shouldn’t be so quick to pull the trigger and that Ahrefs may in fact be what I’m looking for. I will most likely do the trial period for both before deciding, but this article definitely opened my eyes to Ahrefs possibly being my best option (instead of SEMrush). Thanks for taking the time to write this article. Great work.
Brian, I’m going through Step 3, which is referring to the one version of the website. I found a very good free tool (https://varvy.com/tools/redirects/) to recommend. It checks on the redirect and gives you a visual number of hops. More hops mean more delay. For example, if I use your manual method to check on https://uprenew.com, all looks good. However, if I use the tool and check, I realize there is an unnecessary 1 hop/delay, whereby I can fix it. Hope this helps. : )

Thanks for the article, really gives some clear insights.I am currently testing out Ahref’s and have tested Moz and Semrush in the past as well. In my opinion Ahref’s UI is the best and clearest. I will have to test Moz and Semrush again i am afraid to be sure which one to start using. Have been using SE Ranking for rank tracking mostly but have noticed rank positions are not accurate most times.


I recommend using this tool for SEO, It is a no 1 tool if you are doing SEO. If you are doing SEO without using any tool then it is very good but it takes more time and you cannot find accurate data to analyze what doing next with your site. So without wasting any time, this tool helps you to find the right keywords and give you better suggestions for your site and increase your Traffic value. 

Ahrefs is a worthy tool, although I feel they should give new users a free trial instead of the $7 for 7 days trial, which is hardly enough trial period to adequately track a competitor’s website. For individuals/freelancers in the SEO digital space, the subscription pricing is quite high when you’re just starting, but once your clients start to see the benefits, it will be worth it as you get more business. Otherwise, there’s little I found to dislike about Ahrefs.

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.

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.
Another function included in the backlink profile section is the data for Referring Domains. Basically speaking, it shows you the number of websites that are linking to the domain you’ve inputted in the search bar. So, in this instance, I’m using seo-hacker.com as the target website/URL, and the number of referring domains is shown with the corresponding details you will ever need:
