Google Sitemaps

[Satan]

Problems are more likely to be down to not understanding a few things about the format and stuff.

Firstly the change frequency tag - apart from the index on a blog dont set it to anything other than monthly. why? Because apparently G keeps track of whether you are lying or not....

Secondly the last updated tag - if you use it and leave it the same then the bot WILL NOT check to see if the page has changed more often than once a year. Do this on the index and nothing will be found. Either keep it up to date or dont use it.

I use it on my biggest site and find it doesnt help much but neither does it hinder. I find it better to write html sitemaps of the abc sort on larger sites - ie

top level sitemap - index - link abc - link-def - link ghi
Next level sitemap - abc - all pages whose titles begin with a, b or c

Then I place a blank gif with the alt tag -"sitemap for (site name)" linked to the sitemap on the index of a seperate site I own with some pagerank on a seperate IP. This way the indexing of the sitemap and sub pages is assured.
