Google PageSpeed Insights

The PageSpeed Insights (PSI) tool provides real-time performance data for a webpage, regardless of whether it is accessed via mobile or desktop devices. It uses data from the Chrome User Experience Report (CrUX) to provide user experience metrics based on actual Chrome users. Simply enter the website's URL, and the tool will generate an overall speed score. Based on its speed score, the tool classifies the website as fast, slow, or average. It also provides an optimization score that evaluates how well a webpage adheres to performance best practises.

RedBot

This is a fantastic little tool for inspecting HTTP headers. You'd be surprised how many websites have badly formatted headers. Bad headers can wreak havoc on caching, CDN effectiveness, and even cause mobile browsers to display incorrect pages. I use this tool to quickly show customers what headers their site sends. If the application is setting the headers, they can forward this to their developers to resolve the issue.

Moz

Moz analyses data from more than ten different sources, including Google, Yelp, and Facebook, to score your brick-and-mortar business based on how it appears online. The results include actionable fixes for inconsistent or incomplete listings.
