For one of the wordpress posts I noticed that I revised it over 100 times (little revisions). Regardless, that is 100 pings for one page! Big mistake. That page is now no where to be found on Google in the first 15 pages whereas before it was sitting pretty on page 9. Am I right that overpinging was the likely culprit?
It's better to add new content everytime you update your blog coz Google always look for fresh content rather then the one which is being edited everytime with some small additions in that, afterall it's the same old content on the same url which google has crawled previously, it can crawl it once, twice, thrice but not after that coz Google is clever as well. You can add the extra info by adding some content and updating your blog with a new post containing that info, that would really help you.
Its true to say that over pinging excessively can make your blog look like a splog to SE's like google so it could be a probable cause. These days just using pingomatic would be a sensible option as its the one site that's survived the pinging wars and remains technically up to date with all other pinging sites/services so it will syndicate your ping accordingly - one ping to rule them all ;-)
Pingomatic is the default in my WP blog settings. Should I continue to only use this service for pinging my blog or should I add one or 2 others? I don't update blog posts very often but at the same time I don't to be accussed of ping spamming by google. I'm thinking from the angle of SEO / number of ping backs generated for google to recognise on other sites.
