SEO Tools

Tools for what you should check before publishing a page — meta tag checks, structured data generation, and page performance measurement.

What's in this category?

The SEO tools match different moments in publishing. While writing, the Keyword Density Checker and SEO Word Counter look at the text itself. While preparing the page, the Meta Title Checker, Meta Description Checker and SERP Preview help you shape what shows up in search results, and the Open Graph Generator does the same for social shares.

On the technical side, the Schema Generator and Structured Data Validator write and check structured data, while the Robots.txt Generator and Sitemap Generator guide search engine crawlers. After launch, the Core Web Vitals Checker shows a page's PageSpeed Insights score, and the UTM Builder lets you separate campaign traffic in your analytics tool.

Which tool for which job?

Before publishing a new blog post, test the title in the Meta Title Checker, then confirm in the SERP Preview that it is not cut off.
If a shared link shows the wrong image or title on WhatsApp or LinkedIn, fix it with the Open Graph Generator.
Writing markup for a product, FAQ or event page? Start with the Schema Generator, then use the Structured Data Validator to catch missing required fields.
On a brand-new site, keep areas like the admin panel out of crawling with the Robots.txt Generator, and list your pages for search engines with the Sitemap Generator.
To see newsletter visitors and Instagram ad visitors separately, tag each link with the UTM Builder.
If a page feels slow on mobile, check it with the Core Web Vitals Checker.

Things to keep in mind

Length checks are approximate. Google can shorten a title based on display width and sometimes shows its own title instead, so put the important words first.
robots.txt does not hide a page. It only steers crawling. To keep a page out of search results, use a noindex tag.
There is no magic keyword density. Forcing the same phrase in again and again makes the text hard to read.
Do not add UTM parameters to internal links. They can make analytics credit visits to the wrong source.

A short starter list

If you are new to SEO, start with three things for every page: a title that is not cut off in search results, a meta description that says in one sentence what the page offers, and an Open Graph image that looks right when the page is shared. Once those are in place, moving on to structured data and page speed puts your effort where it makes the most difference.
