Two major errors:
1. I develop websites locally on my PC. I want to check them before they are live. I don’t give them ‘.com’ names when they are on my PC. Vovsoft SEO checker can’t cope with that and automatically adds .com on the end of the URL I type in, then of course fails to find the website. Doh!
By the way, I generally use ‘Screaming Frog’ and it is excellent and has no problems checking my local websites.
2. I successfully scanned an external website, then clicked on the ‘Found H1 tags’ tab and got the error:
“System Error code: 1400. Invalid window Handle.”
Then the program hung and I could not exit. I had to end it in task manager.
VERDICT:
Not yet ready to be a commercial product
