Recently I have continued work on SiteHealth.co, partly because I have prioritised my side projects based on a number of factors and it came up high in the list and partly because we continue to require the ability at work to automatically check and track the quality and health of our 50+ client websites.

SiteHealth.co spiders links within a website, downloads the html from the pages and interrogates the page using HTML Agility Pack (available on NuGet) for list of pre-determined issues such as broken links, missing alt tags, heading structure etc etc

It then generates reports and shows charts detailing the number of these issues over time. Used with the comments feature, it can help highlight at what points in time more or less issues were detected
