Mangools has six free SEO tools on mangools.com, and a free browser extension. You can use the tools without a Mangools account. Each tool has a small allowance of searches of its own, separate from the lookups in your plan. A free Mangools account unlocks more in most of them.
When a tool stops working, read the message it shows. The messages differ by tool, and some are misleading. The table near the end of this article lists each message and what it means.
Where to find the free tools
All the free tools are listed under Free SEO tools on mangools.com, which is also linked in the site footer. In KWFinder and the other Mangools SEO tools, open Mini SEO tools in the top bar. The menu is not shown on small screens.
The Free SEO tools page and the Mini SEO tools menu also list SERP Volatility Checker, a page on mangools.com.
AI Search Grader
AI Search Grader asks AI models about your niche and scores how often and how high they name your brand, from 0 to 100. Three models work without an account, and three more when you are signed in. See AI Search Grader: how it works and how to read your score.
SERP Simulator
SERP Simulator previews your page's title and description as a Google result, on desktop or mobile, and warns when they are too long. Editing the preview uses nothing. Its search bar, which loads real Google results, counts toward its allowance. See SERP Simulator.
SEO Content Optimizer
SEO Content Optimizer checks a page against a target keyword, the top 5 Google results and the page's Google Search Console queries. You need a Google account with access to the website's Search Console data. See SEO Content Optimizer.
Reddit Threads Finder
Reddit Threads Finder finds Reddit threads that rank in Google's top 5 for keywords related to your topic. It works for English keywords, in six location options. See Reddit Threads Finder.
SERP Location Changer
SERP Location Changer opens Google's results for a keyword, as seen from another location and language, in a new browser tab. See SERP Location Changer.
Share of Search
Share of Search compares the search volume of up to 5 keywords, usually brands, and shows each one's share. Without an account, it compares the last 12 months only. See Share of Search.
The SEO browser extension
The Mangools SEO extension for Chrome and Firefox brings Mangools SEO data into your browser. It shows more when you have a Mangools account. See The Mangools SEO browser extension.
Do you need a Mangools account?
No. Every free tool works without an account. Signing in to a Mangools account, a free one included, adds the following:
Tool | What signing in adds |
AI Search Grader | Three more AI models: DeepSeek, Claude and Gemini |
Share of Search | The 24-month, 36-month and all-time periods |
SEO Content Optimizer | All missing queries, when a page has more than 20 |
Reddit Threads Finder | More searches and more threads per search, as the tool's banner says |
The tools know you are signed in when you are signed in to Mangools in the same browser.
How many searches do the free tools allow?
Each free tool counts its searches in an allowance of its own. These allowances are not the keyword lookups or SERP lookups in your account menu, and the account menu does not show them. The tools do not show a number either.
When an allowance is used up, the signed-in message says to "wait for the counters to reset". It does not say when. Lookups in the Mangools apps work differently: see How lookups and limits work, and when they reset.
Why did a free tool stop working?
Message | Shown in | What it means |
"You're out of free searches in" and the tool's name | AI Search Grader, SEO Content Optimizer, Reddit Threads Finder | You are not signed in, and the tool's free searches are used up. |
"Looks like you've hit the search limit!" | SERP Simulator | You are not signed in, and the searches are used up. |
"You've used all of your searches. Please upgrade, or wait for the counters to reset." | AI Search Grader, SERP Simulator, SEO Content Optimizer, Reddit Threads Finder | You are signed in, and the tool's searches are used up. |
"Uh-oh! Slow down a bit!" | SERP Location Changer | The searches are used up, whether you are signed in or not. The headline sounds like a speed warning, but it is not one. |
"Whoops! We couldn't dig up anything for these keywords." | Share of Search | Either no data for your keywords, or any other error, including used-up searches. |
"Too many requests!" | AI Search Grader, SERP Simulator, SEO Content Optimizer, Reddit Threads Finder | Requests were sent too fast. Wait the seconds it shows and try again. |
When the searches are used up, try again later, or sign in to a free Mangools account where the message offers one. SERP Location Changer offers Create a FREE account even to signed-in users. If you already have an account, you do not need another one.
A free tool does nothing or keeps loading
SERP Simulator and Share of Search check each search with Google reCAPTCHA. An ad blocker or privacy extension can block it. SERP Simulator then does nothing, and Share of Search stays on "Loading..." or shows its "Whoops!" message. Turn the blocker off for mangools.com and reload the page.
SERP Location Changer and SEO Content Optimizer open a new window or tab. Allow pop-ups for mangools.com.
