The Top [Mostly] Free SEO Tools for Marketers

We know it too well: SEO tools can quickly turn expensive. Marketers—particularly freelancers, small businesses, and start-ups—must familiarize themselves with the best, affordable, or no-cost tools out there. Thankfully, a lot of top platforms now have free versions or individual tools to offer you insights, enhance performance, and do more with less.

This blog brings together information from Google’s work tools and popular third-party applications to create a balanced SEO tool set. Let’s learn about them.

Google’s FREE SEO Tools

Google has a solid set of FREE tools that you can leverage for your business. Below is where each one comes into place in your SEO strategy:

Google Analytics 4 (GA4)

Google Analytics 4 is a marketer’s best friend. It’s a powerful tool that allows you to see data and (believe it or not) analytics on your website’s visitors so you can learn more about them.

You are able to see details about how visitors got to your website, what they did when they were on your website, and learn more about your website visitors as a whole!

This is how you are able to make informed decisions about the marketing strategies you run.

We even have an entire section of our blog devoted to GA4 guides we’ve created here at SocialSurge!

Google Search Console

Google Search Console is very similar to Google Analytics, but it is more specific to your site’s search traffic and performance.

It also helps identify issues that your website currently has and how to fix those issues.

Make sure to tie your Search Console to your Analytics platform to get the most out of it! We put together a guide on how to do this, set up Google Tag Manager, and tie all of these together!

Google Tag Manager

Google Tag Manager (GTM) is a tag management system that helps store and apply all of the tags that you’d otherwise have to manually insert into your website’s code. The most common tags added to GTM are Google Analytics, Google Ads, and Facebook Pixel.

It also makes it easy to tell these analytics codes where they should be applied. For example, if you want analytics only on one page of your website, you can easily do that using GTM!

Without anything added to GTM, it would be an empty shell.

Google Business Profile (GBP)

Google Business Page (GBP) is a free tool that gives you a listing of your business that appears on Google and Google Maps. Your listing can include things like:

• Business Name
• Location
• Business Hours
• Customer Reviews
• Photos
• Analytics for your use

GBP can be one of the easiest and fastest ways online to bring clients to your location and even bring more traffic to your website.

When you talk about SEO, most of the time, you have to hire someone to optimize your website and online brand to get your business found online. Then it can still take months to see results! With GBP, you can see results almost immediately, and you need very little technical experience.

Google Ads

Note: This is the one tool here that is not free. You can set up an account for free, but you do need to pay for the clicks!

Google Ads is a pay-per-click (PPC) advertising program by Google. You ‘bid’ for your rank in Google searches by the specific keywords that you choose.

You can choose multiple keywords and make them very specific to ensure the traffic you will get will benefit you and not waste your money, since you only pay for each click that your ad generates.

Each ad consists of a title line, two descriptive lines, and a click-through link to a specific page on your website.

Google Structured Data Markup Helper

Want to help Google understand your content better (and maybe earn rich results)? This tool is a lifesaver. Google’s Structured Data Markup Helper walks you through adding schema markup to your blog posts, products, local business pages, and more. It’s ideal for marketers who aren’t developers but still want the SEO boost that comes with structured data. Just paste your URL, highlight elements, and generate the code.

Google Chrome Extensions

If Google Chrome isn’t your main web browser, you’re missing out! It’s an incredibly fast browser with many extensions and apps to make your job as a marketer that much easier!

One example is called MozBar, a free Chrome Extension that makes it easy to get SEO stats such as link metrics, domain authority, etc.

Something awesome about using all of Google’s various tools is that you can access all of them with your Google account. You don’t have to worry about multiple usernames and passwords; instead, you just have to be logged in on Google Chrome!

As you can see, Google offers a wide range of services to business owners and marketers. While all of these are important tools, take your time learning and understanding them. They can get a little complex, and it is easy to get frustrated.

Check out all our resources, and you’ll be an expert in all things Google in no time!

Now, let’s look into valuable non-Google SEO tools.

Must-Have Non-Google SEO Tools (Free or Freemium)

While Google tools like GA4 and Search Console are vital to your SEO success, they don’t cover everything. Fortunately, there’s a wide world of third-party tools—many of them free or freemium—that fill in those gaps and make your SEO workflow easier, more visual, and often way more insightful.

These are our go-to picks for anyone looking to level up their marketing stack beyond the Google ecosystem:

Screaming Frog SEO Spider

Screaming Frog SEO Spider is a desktop-based crawler that helps you dig deep into your site’s structure. It identifies common SEO issues like broken links, missing meta titles or descriptions, duplicate content, redirect chains, and more.

The free version lets you crawl up to 500 URLs–plenty for most small-to-mid-sized websites. If you’re an agency or managing larger sites, the paid version unlocks even more technical audit features.

Ahrefs Webmaster Tool

Ahrefs is a big name in the SEO world, and their Webmaster Tools version brings some of their most powerful insights to you for free.

You can use it to monitor backlinks (who’s linking to your site), discover keyword opportunities, and perform site health audits that alert you to technical or performance issues.

GTmetrix

A slow site is an invisible site. GTmetrix helps you fix that.

This tool analyzes your website speed and performance, giving you actionable suggestions to make it load faster, like compressing images, minifying code, or deferring scripts.

AnswerThePublic

If you’ve ever struggled with what kind of content to create, this tool is for you.

AnswerThePublic visualizes questions people are asking about any topic you search. It’s ideal for brainstorming blog titles, FAQs, and pillar content that aligns with real user search intent. The free version has a daily limit, but it’s super powerful.

Pro tip: pair it with “AlsoAsked” to get even more out of your research!

AlsoAsked

Ever seen the “People Also Ask” boxes on Google? AlsoAsked helps you dive deeper into those queries.

This tool organizes those related questions into neat, visual mind maps. You can literally trace how one question leads to another—and use that intel to build better content clusters or optimize for long-tail keywords.

SEOquake (Chrome Extension)

SEOquake is like having a mini audit tool right in your browser.

This handy Chrome extension lets you run on-page SEO checks, analyze keyword density, and even review SERP metrics in real time while you’re browsing. Additionally, it integrates with Google Search Console and Google Analytics, giving you extended reporting right where you need it most.

If you’ve spent any time in GA4, you know the default channel groupings can be… messy. GA4 Fixer is a free Chrome extension that lets you rename and reorder your acquisition channels in GA4’s Explorations workspace—without altering any raw data. It makes reports actually readable, which helps when explaining traffic sources to clients or execs who just want to know what’s working.

Query Hunter

If you’re already using Google Search Console (you should be), Query Hunter is like putting a spotlight on the low-hanging fruit. This tool pulls in your GSC data and shows you which URLs rank on page 2 or beyond—and which keywords they’re ranking for. That’s gold for marketers because you can spot opportunities to refresh content, add internal links, or tweak meta titles without creating anything new. Massive time-saver. This tool is free to try with a premium option.

Keyword Surfer (Chrome Extension)

Need keyword data, fast? Keyword Surfer is another Chrome extension that shows you estimated search volumes, cost-per-click, and related keywords—directly in your Google search bar.

It’s a lightweight, straightforward extension that’s perfect for quick checks, competitor research, and on-the-go inspiration.

Rank Math (for WordPress)

If your site runs on WordPress, Rank Math can be a valuable tool.

This all-in-one SEO plugin helps you manage on-page SEO, create schema markup, generate sitemaps, and even analyze your content in real time with helpful scoring.

It’s beginner-friendly and includes a ton of features for free, which is ideal for solo marketers, bloggers, and small businesses who want powerful SEO without the tech headaches.

Meta Pixel Helper (Chrome Extension)

Running Meta Ads? This is a must. Meta Pixel Helper is a Chrome extension that tells you whether your Meta Pixel is properly installed on a site and whether events like “View Content” or “Add to Cart” are firing. This is essential for retargeting, conversion tracking, and making sure your ad budget isn’t going to waste. Think of it as a quick diagnostic tool before you start scaling spend.

ChatGPT Search Query Extractor

Need to find exactly what someone typed into ChatGPT?

The ChatGPT Search Query Extractor scans and pulls out search-style prompts from ChatGPT conversations. Perfect for SEOs and marketers who want to reverse-engineer real user queries. It’s especially helpful for identifying long-tail keywords, search intent, or common phrasing in natural language.

Pro tip: Use it alongside a keyword clustering tool to spot content themes or optimize existing content.
