Yes, I'm using a sitemap generator and sending it to Google.
Probably more important now since a few of us have brand new boards.
I ran without a sitemap for years and google was populating nicely. In fact the only time I needed a robots.txt file was when yahoo slurp pretty near piled us into denial of service a few years ago with their bots...they kinda went crazy for a month or two.
I often wonder if, a sitemap is neccessary if google is having problems indexing content, for whatever reason and one needs to "jump start" the indexing process.
I've added a sitemap now and let's see what happens, because at the mo. with a fresh new board, coming in with no import, building content slowly but surely, the big "g" seems to be ignoring me.
To note, in the past, google was
so efficient it was quite entertaining to watch:
I'd make a post edit, something as tiny as adding a full stop (or period) to a single post, go and see "Who's Online" and straight away, sometimes within seconds, I'd see the googlebot spidering away doing its job, crawling, fixing and then running off into a dark corner. Fantastic!
One most obvious question I don't see asked is:
"When I've submitted with the sitemap, links are sweet and things are running smooth etc. Can I then delete the sitemap files and run without them?"
Come to think of it, possibly more pressing is:
"When I've done the sitemap and it's all indexed etc. Is any modification that generated them, still neccessary to be installed?"
