A great post with great data, but I have to ask one question: do you know that search ranking was adversely affected on the sites you surveyed? Or are you simply reporting that you surveyed sites that contained these errors with the stated frequency?
Glad you liked it. As to your question, we just collected the statistics on the errors found on the websites' our users analyzed. But all these errors affect rankings more or less.
This is great! Thank u for the research! :)
Thank you for the feedback! ;)
