Spiders

Which spiders do we want to encourage to trawl through our websites for indexing purposes?

Is there, say for example, a website listing names of the top 100 spiders and the search engines they provide data to for indexing?...together with Add URL pages.

Even though we may be reliant on traffic from the top few SE's, are there others we are maybe neglecting for that extra few percent of traffic?

Hi QGJ, I don't really understand your question, 3.36am and all that, could you elaborate a little please?

Cheers,
