If you’re an SEO analyst and/or if you work in the SEO industry, you already know the importance of the SEO tools to run a successful campaign. But there are a lot of SEO tools in the market and it’s not easy to choose between all of them.

We know the frustration of choosing the right SEO software among all of the different options because we have been there. Reading and viewing tons of online reviews and yet, we were not sure if we should invest or not. So we decided to try and we have spent a lot of time and a bit of money in order to use the most popular SEO softwares recommended by SEO experts.

In this article, we have tried to put together a list of 10 best SEO tools that we are now using in our agency to enhance our efforts. This list is subjective based on the work we are doing for our clients so if you think some must-use tools are missing feel free to comments to complete this top 10 must-have SEO tools for agencies. But before starting the list we would like to introduce the 2 big players that we over use at Ultimate Index.

SEMrush vs ahrefs

You probably already ask your self if you should use SEMrush or ahrefs or both?

Both SEMrush and ahrefs are, what we call in our agency, a 360-degree tool. A 360-degree tool covers the major SEO features that you need for your work. These features include but are not limited to Technical SEO, Keyword Tools, Backlink Analysis, Traffic Analytics, Competitor Analysis, etc. Please note that we won’t detail all the amazing things you can achieved with these 2 tools. We will just do a really quick overview of each tool because we also want to introduce other options since SEMrush and ahrefs can be a bit pricey depending on your needs.

We actually use the 2 tools in a different way. The two SEO tools have more or less the same major features but each of them have their own pro. Even though SEMrush seems to be more marketing oriented and ahrefs seems to more purely SEO oriented.

  • With ahrefs we are mostly using keywords research, site explorer and bulk export of the site audit feature.
  • With SEMrush we are mostly using site audit, keywords position tracking, Sensor (For the SERP Volatility), social media planner and Backlinks automation from their Link building section. The real plus in SEMrush is the report section, a time saver for us to send our reports to clients.

Let’s detail a bit more SEMrush and ahrefs and start our top 10 SEO Tools.

1. SEMrush SEO Toolkit (Freemium)

ahrefs is another 360-degree SEO tool for professionals. The interface of ahrefs is little bit more difficult to navigate compared to SEMrush. That’s why the user experience of ahrefs, according to us, is less intuitive than SEMrush but the data they provide seems to be a bit more accurate or at least updated more often (Especially on the backlinks profile, some).

So, if you are a very experienced SEO expert, then this SEO tool is also a good choice for your SEO agency. Two of are favorites features of ahrefs are their Site Explorer and Keywords Explorers tools which are a gold mine of information for your campaigns.
