17 Free(ish) On-Page SEO Tools To Increase Organic Traffic

Optimize Meta tags, create unique content, link back to other pages, use alt-text in all images…..

These are textbook on-page SEO techniques. While they might look easy to execute, that’s not entirely the case. And this is exactly why having the right set of tools by your side is rather imperative.

They can make the entire optimization process much more efficient, time-effective, and data-approved.

Here are the 17 best tools for on-page SEO that top experts use and recommend:

(And, yes, they are all FREE)

1) PageSpeed Insights

Google’s own, PageSpeed Insights checks the speed of your website on desktop and smartphone.

It returns back with a handful of optimization suggestions that you can implement to further boost the loading time of the website and help your SEO.

2) GTmetrix

Another tool to check the speed of your website. But unlike Google PageSpeed Insight which scans the code of the page, GTmetrix actually loads the website as users’ browsers do. You can call it a more human side testing of your website.

GTmetrix tests your website, tells you what is slowing it down, and also offer helpful resources to speed it up.
