ValidateHTML's answer
Instead of opening 5 different tabs (W3C for HTML, JSONLint for JSON, separate tools for meta tags, Open Graph, accessibility), ValidateHTML combines everything in one interface. Plus you get a quality score that tells you exactly where you stand.

ValidateHTML's answer
I was tired of opening 5 or 6 different tabs every time I needed to validate my code before deploying. W3C for HTML, JSONLint for JSON, random sites for meta tags. So I built one tool that does everything, with a quality score to instantly know where you stand.

Semrush is very popular and next level performance tool which varies competitors, analyzes and tracking of any domain website, which provides you full information what's the position of the website, overall traffic, etc. This tool is easy to use with limited trial 7 days, after the trial ends, has limited features work on free plan.
