TagCrowd
Screenshot from Tagcrowd.com, August 2021
TagCrowd is one of the best free keyword research tools for SEO.
Its value proposition is simple: you can visualize word frequency by creating word/text/tag clouds without the hefty price tag of tools like Buzzsumo and Ahrefs Keywords Explorer.
Keyword frequency remains an important focus of on-page SEO.
If you’re targeting specific keywords but use them sparsely, you’ll have trouble ranking for those keywords. On the other hand, stuffing keywords on a page with too high a frequency might trigger a Google penalty for what’s perceived as a black hat SEO technique.ADVERTISEMENTCONTINUE READING BELOW
You can use TagCrowd to determine the optimum keyword frequency for a topic by checking competitor articles.
Key Features:
- Beginner-friendly user interface.
- Supports competitor SEO analysis.
- Multiple ways to add content:
- Upload a file.
- Enter webpage URL.
- Paste page text.
Best keyword research tool for: Visualizing keyword frequency
Pricing: Free
Google Analytics
Complete web stats and search insights

Limitations: No limitations for its usage, but queries that are sending you organic traffic are hidden
Quite possibly the most powerful free analytics tool available, Google Analytics tracks pretty much every bit of traffic you can imagine on your website—where it comes from, which page is receiving it and so on.
While it’s not purely for SEO, it’s still a helpful tool to track if you’re getting traffic from organic search.
However, Google Analytics has since stopped showing which keywords are sending you those traffic. You’ll have to pair it with a tool like Keyword Hero to uncover what’s behind “(not provided).”
Alternatives:Matomo, Open Web Analytics, and Clicky
Classy Schema Structured Data Viewer
Check if your structured data was implemented correctly

Limitations: None
Always double check to make sure you’re implementing the technical aspects of SEO right. Use this tool to see if your structured data/schema markup was done correctly.
Alternatives: Google Structured Data Testing Tool (deprecating soon), Google’s Rich Results Test (currently does not test for all possible schema markups)
SERP Robot
See your ranking position for up to five keywords

Limitations: None
Enter any website or web page and up to five keywords to see where you rank for each of them. Check your competitors’ rankings too.
XML Sitemaps

Simply enter your site’s URL and some optional parameters, and XML Sitemaps will create a sitemap that you can upload to Google Search Console and Bing Webmaster Tools.
Robots.txt Generator
Generate a robots.txt for your site

Limitations: None
Robots.txt files let the web robots know what to do with a website’s pages. When a page is disallowed in robots.txt, that’s instructions telling the robots to completely skip over those web pages.
Alternatives: YellowPipe’s Robots.txt Generator
Google Search Console
Constant website analysis, alerts, and error reports

Limitations: Only shows a handful of technical SEO issues, the top 1,000 backlinks and top 1,000 organic keywords
Google Search Console gives you a taste of what the most used search engine thinks of your website. You can use it to check and fix technical issues on your website, see important SEO data like clicks, impressions and average ranking position, submit sitemaps and more.
If ranking in search engines like Bing and Yandex are important to you, then take note that they have their own “search console” too.
Alternatives:Bing Webmaster Tools, Yandex Webmaster Tools
SimilarWeb
