The martech landscape has grown astronomically in the last decade, and so has the need for SEO software. The benefit to this is that marketers have more choices than ever when it comes to choosing the best SEO software for their business.

On the other hand, with so many choices, it’s easy to get overwhelmed. That’s why we put together this list of the best SEO software for 2021 according to users, reviews sites, and other professional search engine optimizers.

What is SEO software?

SEO software refers to tools that help you with some aspect of SEO. This might be a backlink checker or a keyword research tool. Marketers use SEO software to optimize their content and their websites for search engines so that their content has a better chance of ranking highly on a search engine results page (SERP).

Here are 40+ of the best SEO software on the market in 2021.

Best overall SEO tools

There are many SEO tools on the market. Some are targeted tools (tools that only help with a specific aspect of SEO) while others provide an all-in-one solution for most SEO needs. The following are the best of both worlds, which you’ll find in the marketing stack of many successful businesses practicing SEO today.

Best SEO software for small businesses

Just because you’re small doesn’t mean you have to skimp on SEO software. Small businesses can compete with large, well-funded businesses with the right tools (and excellent content).

Even if they’re just a content creation agency, they’ll still want a tool powerful enough to provide high-quality SEO-focused content for their clients.

  • Ahrefs—ranked #1 by 48 experts, Ahrefs is affordable software that is powerful enough for a large agency with multiple accounts yet intuitive enough for agencies new to SEO to use and understand.
