I've used a couple of SEO software programs over the last 4 years. Moz, Serpstat, SEM Rush and now Ahrefs. Since the bulk of my focus is actually building links, I think Ahrefs has the most reliable results. For example, if you checked the backlink profile of 10-20 websites on Ahrefs and compared to another SEO software provider, I bet that you would average at least 10-15% more results with Ahrefs. That can be a lot more opportunities! Their keyword phrase tracker seems to work pretty quickly and seems to be accurate.
Another advantage of using Ahrefs is their “Fresh Index” “Live Index” switch that displays backlinks that Ahrefs’ crawler found. The main difference between the two is that the Live Index is updated every 15-30 minutes to show live links in your site. For Fresh Index, it is updated at a much longer timeframe, but it still displays dead links which give you the chance to reclaim or change the dead link.

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. 

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.


Of the three popular backlink reporting tools (Majestic, Moz, Ahrefs), Ahrefs provides the most useful link data. Even in other areas of SEO, Ahrefs seems to always keep their toolsets fresh. They continually add in useful tools and features that make other software suites less relevant. The most recent addition is their site audit tool which provides a beautiful visualization of technical site issues.
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.
However, if possible, I would like you to expand a bit on your “zombie pages” tip..we run a site where are definitely enough pages to delete (no sessions, no links, probably not even relevant with the main theme of the site, not even important for the architecture of the site)..Nonetheless, I am not very sure what is the best technical decision for these pages…just deleting them from my CMS, redirecting (if there is a relevant alternative) or something else? Unindex them on Search console? what response code they should have? ..

The errors in technical SEO are often not obvious, and therefore one of the most popular. Mistakes in robots.txt and 404 pages, pagination and canonical URLs, hreflang tags and 301 redirects, http vs https and www vs non www versions: each of them can seriously spoil all efforts to promote the site. One quality SEO website analysis is enough to solve all the main problems in this part forever.

Use our Alibaba longtail keywords finder to tap into the millions of products you can buy and sell. No matter if B2C or B2B, for dropshipping or Amazon FBA, shipping containers or airdropping, here the professionals trade.
Depending on the plan, you are only allowed up to 100 domain searches a day. If you purchase their top tier plan you only get double of that. Sometimes it can take you several days to do certain types of research. This can start to get a little bothersome as we work with several clients and all of them need to use this software to make sure everyone is getting the best work that we have to offer.

One thing I like about Ahrefs is that it's straight and to the point. It's very easy to get in, get your data, and get out. Each report does pretty much what you expect it to. This report shows the referring domains + number links coming from that domain. You can access the links from each domain by clicking the Expand button next to the referring domain:
Brian, I have a burning question regarding keyword placement and frequency. You wrote: “Use the key in the first 100 words … “. What else? I use Yoast and a WDF*IDF semantic analysis tool to check the content of the top10 rankings. Pretty often I have the feeling I overdo it, although Yoast and WDF/IDF told me I use the focus keyword not often enough.
One thing I don't like is that Ahrefs sometimes does not provide exact keyword search volume. Instead – it provides approximate numbers which confuses us in cases when we think a keyword should get more traffic that it actually does once the SEO content is published. To get the most up to date and exact numbers, you'd better off use Google's keyword planner.
Hi Andres, sad to know that you’ve not discovered few toxic links using SEMrush. How did you find those toxic links? Have you used any other tool to find them? Also you might want to get in touch with the SEMrush support team and let them know about this issue, so they’ll look into it. But if you still are not comfortable with it, you might want to give a try to Ahrefs for a month or two to really find out the best one among them. I’d suggest you give a try to Ahrefs for some time to see if it’s the right fit for you.

As a long time Moz user and I might even say a super fan of their product, it feels really odd to be writing a review of Ahrefs. But here we go--I love Ahrefs. The design, the UI, the gigantic keyword database and now the newly redesign site audit are a thing of beauty. I continue to be impressed by the data they provide, features that are added frequently and my favorite feature has to be the top pages report. (Not sure why I love that so much--but it just makes it extremely simple to research a site or competitor with that report.)


Thank you for the great checklist. It is really useful and gave us a couple of new hints on optimization process. We’ve been using WebSite Auditor and found it exremely helpful in site’s structure and content analysis, bringing all the statistical information on the validation errors, social mentions, duplicate stuff, etc. under one roof. Still there is so many different SEO information you sometimes cannot understand what to start with. Fortunately you answered this question. Thank you again!
