Free SEO and marketing tools
Page checks and link builders that help your pages get found and clicked.
Most SEO and campaign problems are mechanical: a page with a missing meta description, a redirect chain that wastes link value, a campaign link without UTM tags so the visits land in the wrong report, a URL slug full of stop words and stray characters.
These tools fetch the real page or build the exact link, so you are checking what Google and your analytics will actually see. A chatbot can explain what a 301 redirect is, but it can't follow yours and tell you there are three hops instead of one.
Every tool is free and translated into 25 languages. You can use them without an account, and a free account raises the daily limit.

Common questions
Do the meta tag and redirect tools check the live page?
Yes. They fetch the URL when you run them, so they show the page as it is right now, including changes you made a minute ago.
Which UTM parameters do I actually need?
Put utm_source, utm_medium and utm_campaign on every campaign link. Add utm_content when you test two versions of the same ad or email, and use utm_term only for paid search keywords.
