The Best Free Tools for SEO

Here at Seer, we love saving money (and our clients' money, too). When it comes to SEO, there are hundreds of tools out there, some with a pretty hefty price tag. Of course, premium tools are super valuable when you require high limits, advanced functionality, or stored data.

But here’s the truth: For most SEO tasks, especially keyword research, a free tool does the same as one with a premium price tag.

That’s why we’ve asked our team about their favorite SEO tools. Here’s a list of impactful, easy-to-use, Seer-tested tools. The best part? They won’t break the bank.

We have included a description to help you understand how to use each of the tools below, but you can use this table of contents if you want to learn about a specific tool or application.

Analytics Tools

Bing Webmaster

Bing Webmaster Tools offers insights into your site with a holistic dashboard, sitemaps, crawl control settings, page preview feature, and much more.

Google Analytics & Data Studio

This one may seem like a no-brainer, but many forego that Google Analytics is the bread and butter of digital marketing. Track your SEO efforts and take advantage of a number of metrics, including site visitors, traffic, and more.

Data Studio allows you to piggyback on your data and create sleek, easy-to-build custom reports and interactive dashboards. In terms of free data visualization tools, Google Data Studio is definitely a Seer favorite. Using Data Studio for the first time? Check out our guide!  

Google Search Console

Google Search Console, formerly Google Webmaster Tools, provides some of the same data as Analytics, but more focused on search optimization. It provides information about how Google crawls your site and provides uber-accurate keyword data. One of the most valuable aspects of this tool is the ability to check indexing status.

Screaming Frog is definitely a Seer favorite for link crawling. While unlimited access is a premium feature, this software offers a free version that allows up to 500 URLs per crawl.

Keyword Research


AnswerThePublic is one of my personal favorites for finding questions that people are asking around your keywords. It’s a keyword data visualization tool that helps you find content ideas by organizing your keywords into categories that consist of who, what, when, where, and why as well as how, can, are, which, and will. While the free version doesn’t display MSV, it’s a great tool for identifying questions your audience has.

Keyword Planner

While Google’s Keyword Planner is a Google Ads feature built for PPC use, it’s still super helpful and relevant for SEO. Unsure about the Google Ads UI and where to start? Discover how to access Keyword Planner and start discovering new keywords in no time.

Keywords Everywhere Extension

While I am absolutely devastated that Keywords Everywhere took away MSV from the free version, it’s still super useful for keyword inspiration since it allows you to view relevant keywords as you search the web.

It’s super helpful in gaining an understanding of how questions are asked on search.
