Adding Sitemaps advisable for a mature, well indexed site?

[Jack_Hughes]

If you have a mature (6+ years) site that is ranking reasonably well and has been indexed for some time is there any reason why providing a site map would be a good idea? Are there any downsides?

There's only an upside as far as I know - any doubts about it came from the very early days of XML sitemaps. The upside is the potential for more timely indexing of new content, and more complete exposure of the site for spidering (and potential inclusion in the index).

Do you think Google could look at it favourably in the sense that a sitemap will generally correlate with a site which is properly maintained and operated?

It's the same line of reasoning I thought that might exist in connection with buying or sourcing quality links...the fact is that a company who can afford to do this would generally be a company with funds to do so, which would imply some sort of client base or possibly valuable service generating those funds?

Do you think there is any truth to this?

The other side of this is if your content is already indexed, then, it might not be worth the effort. For sites doing well, we usually haven't seen an improvement unless there is content that hasn't been exposed to the bots.
