I noticed some of my sites drop significantly for many of the keywords that I rank for in Google. I rank in the top 10 for several keywords (on several different sites) and my traffic came to a screeching halt today. My rankings are down to the 7th or 8th page or lower! After doing some digging around, I decided to login into my Google Webmaster tools. Sure enough I found a warning next the sitemaps for all my affected sites.
The warning was: "Some URLs in the Sitemap have a high response time.
Some URLs listed in this Sitemap have a high response time. This may indicate a problem with your server or with the content of the page."
My guess is this is the reason for my drop in ranking today. However, I am not sure how to resolve the problem. Could anyone offer some advice? I have not changed the contents of the page or the site for that matter in over 3 months?? (for most of the sites anyways).
I don't see any noticeable slow response time; however, does anyone know of any tools or sites where I can check my response time?
Any other advice to clean up this mess?
