The following free keyword tools will help put publishers on the path to top rankings.
The tool also generates a search term relationship map, grouping the different search terms into a visual map that shows the base keyword terms (primary connections) and the search terms that are related to it.
Below is an animation showing the main keyword in the center.
Around the main keywords are the primary connections which are variations of the main keywords.
Connected to the primary connections are the keyword phrases that are related to the second-level keyword phrases.

“Our free tools connect to the same database as our main tools. The sources are as usual: Google Keyword Planner, clickstream, and data partnerships.”
Regardless of where the data comes from, the tool is a useful resource for generating article writing topics.
The free Siteliner duplicate content tool is a scanner provided by CopyScape (an anti-plagiarism service).
Siteliner’s top feature is its ability to identify pages within the site that have similar content. This makes it easy to spot opportunities for improving content.
It’s best for articles to feature content that is unique to each article.
Depending on how much content is similar, articles that share content can create a situation where Google may have to choose which page is more relevant and make one canonical.
Eliminating duplicate paragraphs across articles will help web pages differentiate themselves.
The scanner is limited to 250 pages. Nevertheless, it is useful to alert you to a possible problem with thin pages.
The Worldwide Web Consortium publishes an HTML checker that also checks what the heading outline (H1, H2, etc.) looks like on a web page.
This is a really great tool for checking out how Google sees your web page or a competitor’s web page.
Tick the “Show Outline” option in order to see how your heading elements look to a search engine.
The results can be eye opening and reveal issues with your website template.
Select the Show Outline Box to see headings on a web page. Then, tick the box to show outline. The free HTML validator will show you what your heading tags look like to Google.
The validator can sometimes choke on really bad HTML, but there’s a way to get around the coding errors.
Restart the process, but this time, check the More Options section and choose a document type. The heading checker will work, guaranteed.
Free SEO Website Crawler
6. Screaming Frog – Free For 500 URLs Or Less
Industry-leading site auditing software Screaming Frog offers a free version that’s perfect for auditing smaller sites that are under 500 URLs.
It’s a powerful way to crawl a site and learn if there are any problems.
Screaming Frog automatically provides information about your outbound links, internal links, your images, response codes that various pages give, and information about title tags, meta description tags, headings, images, and pretty much everything about a site that a publisher would want to check for site health and mistakes.
Screaming Frog allows you to set the user agent to emulate Googlebot, Bing, Chrome, and anything else you want in order to see how your site responds, providing a true insight into how the search engines and users are encountering your website.
Netpeak Spider is another crawling tool that has a generous free version that can crawl up to 100,000 URLs.
The tool provides data on over 80 SEO-related issues and checks on over 100 technical website issues.
It also has other functionalities related to competitor research.
Overall, the free version of the Netpeak Spider makes a useful complement to the free version of Screaming Frog, as they both have different features and present data in different ways.
Xenu Link Sleuth is the old-school SEO tool of choice when it comes to a free site crawler.
It’s described as a broken link checker and it does a great job of that. It generates a report for both internal and external broken links.
But, Xenu does so much more than check for broken links.
Xenu can output a report that provides a quick overview of page titles, orphaned pages, redirects, and pages that are not found (404 response codes).Xenu Link Sleuth free website crawler and broken link checker.

Free Website Security Audit Tools
Many SEOs don’t consider security as part of an SEO audit.
Security only becomes an issue after a site’s been hacked and the rankings dropped.
In my opinion, website security should be a component of an SEO audit.
A secure website is a major part of how well it ranks and encourages sales. That’s why I include a thorough security audit with every site audit I perform.
