There are plenty of free SEO tools that will help to make the optimization process easy, save time and eliminate guessing. Search engine optimization is key for increasing visitor traffic to a website.
List of free SEO tools that helped me to increase site visibility and traffic.
Site visibility increased more than 4 times over the last 12 months.
Mostly thanks to these tools and content creation.
All of these tools are free. Some tools have usage limits in order to cover running costs.
Free SEO tools
Google is one of the main search engine traffic sources for most websites. There is Google Search Console to make indexing and ranking processes easy.
It monitors the technical health of your website so you know that your content is indexable and consumable by real people. Without it, the SEO of your website will be mostly guessing work.
- Content indexing report (I use it to detect and fix indexing issues)
- Sitemap submission
- Rich snippets report
- Keyword and page search performance report
- Page experience
- Core Web Vitals
- Server health
- Internal and external links
All of these are free.
Do you wonder why?
Because google wants you to create a usable website with great content. Users will be happy using google to find important information on the internet.
Best feature: keyword performance report
You get a detailed keyword performance report for the whole website. Reports can be filtered by individual pages.
This allows you to track individual pages with historical clicks, impressions, click through and position data in google results. Learn from the best performing pages. Find underperforming pages and enhance them with more updated content. Remove completely irrelevant pages from your website.
You can track websites that you work on after registration in Search Console.
When you need to find easy to rank keywords for free then the best service to use is KWFinder. With a free account you get 5 keyword research limits every 24 hours. It is enough for most new blogs that are starting to generate some content for their blog.
As an added bonus when you register for KWFinder service you can use the same account for promoting their SEO tool as an affiliate. No need to wait for approval.
Mangools SEO tool offers:

KWFinder shows keyword difficulty so you will know which keywords are easy to rank. Once you rank for many long term keywords you will start ranking for main keywords with much high traffic potential.
Free account limitations
To use KWFinder you need to register with your email address. After registration you can search 5 keyword ideas every day. Every search will show 15 related keywords with keyword difficulty and search volume for each of them.
As a new user you may get increased limits for the first 10 days.
What I like in Mangools is that with a free account you can use all features of the SEO tool that is available in their paid plans. Paid plan has the same features but with increased limits.
PRO tip: Pay attention to NOT USE chrome or firefox extension. Every time when you click on an extension it will use your daily limit.
Be wise and use your daily account limits by manually engaging inside your account dashboard.
Optimizing WordPress websites for SEO should be done with plugins. Rank Math SEO is a plugin with multiple modules that covers all areas of your website optimization.
I have been using Rank Math SEO for more than a year.
Check these results that motivate me every time I visit the Rank Math SEO dashboard.
Did you notice the Total Keywords report?
This is not available in Google Search Console. It is calculated by Rank Math every time when it gets a report from there.
I am loving it and excited to see it growing.
Plugin has many features including:
- Sitemap generation

This is one of the least known free online SEO tools that detects technical issues on your website. Siteliner helps to detect indexable pages, page size, word count, Page Power, duplicate content, common content, page load time, internal links etc.
User interface is simple and fast.
After scanning your website you will see how it compares to all other scanned sites.
Which can be used to know how many internal and external links you should add in your articles, how many words should you use etc.
Page Power – is an internal page rank that is calculated using internal links. It is a way to see how effective your internal linking pyramid site structure is. Important pages should have higher Page Power.
There is no limit in the number of websites you can scan. Which means you can scan competitor websites and detect their important content by Page Power (internal page rank).
Best feature: Duplicate content detection
Report will show you pages with most duplicate content. Each page has match percentage and matching pages.
I have used duplicate content detection to understand the reason when the number of indexed pages started to decrease.
After finding and fixing duplicate content issues, a number of indexed pages started recovering. Check detailed recovery case study here.

It gives plenty of info about your website. Good for finding unoptimized pages in bulk. Like thin content, few internal links, show or log page titles etc.
Beast feature: visual site structure
Force-directed crawl diagram imitates search engine crawlers and shows your site structure. Important pages are displayed bigger. Link equity flows to levels below. All pages reachable within 4-5 levels. See how I used a screaming frog to pyramid site structure on my website.
You can scan only one project at a time. Project cannot be saved so you need to recrawl it each time.
Completely free SEO crawler that works on your computer. SEO Macroscope allows you to scan any website for technical SEO issues. No limitations at all.
Desktop SEO scanners are generally slow. SEO macroscope allows you to save a scanned website session and use it later without need for scanning again.

Best feature: Orphan page detection
Sorting pages by incoming links helps to detect orphaned pages. You can export reports as excel documents and filter pages with the least number of incoming links.
One of the least known SEO tools in the market. Maybe because of its not original name. Anyway this is desktop software for site auditing.

Google has a keyword planner tool that can be used for finding new keyword ideas. It shows monthly search volume, competition (for google ads) and CPC (cost per click for google ads).
Keywords with high CPC have more commercial intent. Content optimized for those keywords converts well for selling products and services. They can also bring high adsense and affiliate revenue.
