Really fast and efficient, reports and information are well organized. Have used a number of other testers for broken links, etc. None provided so much useful information, so quickly and so easily. It seems like magic
Love this extension! Shows me everything relating to my website (redirects, alt tags missing, sitemap, safety, and more!) and allows me to make sure I’ve done everything possible for a client.
Really slick, took me less than an hour to compile a list of things we had overlooked in our rush to launch. As a product manager, I really appreciate it.
This makes checking to see if [there’s] errors on websites that I’m working on a breeze. … I am so glad that I found this wonderful tool.
I love this tool, as someone who’s relatively new to SEO I need all the help I can get. This tool is absolutely amazing for showing you what you need to improve.
