I need reliable and easy to apply software to build an evaluation instrument that allows for data storage and extraction. Coders will use it to measure a variety of features in approximately 200 websites.
I am building a measurement tool with dichotomous questions that will be used as an assessment device in websites. It would be convenient as an online instrument or software that can aggregate answers and generate reports. Not so sure Excel or other spreadsheets would do that. I will try GTmetrix.
Maybe you need to have a look on WebPagetest, which is a free online tool that displays the load time of your web page as well as 6 different performance grades and it gives you the ability to select the country from which to run your test. This can be used to track how your speeds vary across the world. Finally, it is completely free.
If you're looking for a tool to evaluate content quality you might look at Xenu, an open source Windows app. It's a crawler that is used for content inventory and search engine optimization. A tool similar to it on the Mac side is Screaming Frog SEO Spider.
Thank you all for your responses. Todd, as far as I know Xenu helps you find broken links, and is not open source...but probably it's free of charge. Haven't used a web crawler or other web developer tool before, so I might as well give it a try.
Xenu does more than find broken links. It will pull core HTML tags (H1, Title, Description, etc.) but you can also set up regular expressions. There is a forum of users and the developer, although not working on the tol any longer, often replies with an answer.
