Excelente!!!
BUY THE PAID VERSION (the free version is great, the paid version is absolutely wonderful!) This makes checking to see if errors on websites that I'm working on a breeze. I just click refresh and jump to another tab while i wait. AND THE EXPORT FEATURE!!!! OMG, if you are a self-confessed spreadsheet nerd such as myself then CHECKBOT WILL CHANGE YOUR LIFE. Literally in one click, you get a .zip of all of the data that was scanned and collected (and it is a lot). I use this every time i'm preparing to transfer a website / make structural changes. It's the easiest one click back up. As for the SEO and Security analysis, welp, it's great, and easily comparable to other SEO audit software that I have used. Checkbot is a daily "Go-To" for me. I am so glad that I found this wonderful tool. PS: About the support staff: I've had one strange error in the past few months. The preview of the website that was loading up messed with the ability to view a section of the tools report. I submitted a support ticket and within an hour I was in communication with them and they got it fixed. (this was on a Saturday btw....)
Excelente!
Very useful. Easy to understand.
Really helpful SEO optimization analyzer
Intuitive, I liked it.
Excelente Resultados excelentes de SEO check, Speed check e Security Me ajuda muito nos meus sites e dos meus clientes
Fonctionne parfaitement, mis a jour régulièrement. Rien à dire sauf MERCI
Great app - hope to see more updates soon I'd like to see: - spell-check content (maybe... I realise this may give lots of false-positives, but if this was an optional test I think it could be worthwhile) - check if OpenGraph meta tags (if included) are valid. It'd be good if it checked if the linked og:image was a valid URL (must start with HTTP or HTTPS) - Check if included JavaScripts have security vulnerabilities. Lighthouse already does this, but would like it if Checkbot checked also. - More ideas borrowed from Webhint and Lighthouse would be good.
Easy to use, a really useful tool, breaks everything down into more understandable chunks. Great!!!
