I've got a friend whose main page is indexed by google, but nothing else seems to have been indexed since last year. I can see no reason why this should be the case. There's no robot.txt, no no-follows. Can anyone think of anything else that would stop google following links and indexing the site ?
How are the links to the other pages implemented? Are they standard text links or is your friend using something unspiderable. If we had a URL for the site we could probably find out for sure.
The most likely reasons are: 1.) Not enough links to the site so Google doesn't see it as "important" enough to index 2.) They are using a database with urls ending like .php?d345345gfd2344wer 3.) The site navigation isn't great so combined with #1 Google just doesn't care. 4.) All the subpages are being seen as duplicate content What you can do is create a very organized and efficient site map and get some links for that. Having a link to the sitemap in your signature at a big forum can help. I suppose you could try sigtraders if you don't already have lots of posts (thats not an endorsement but it does seem to fit the situation).
If you haven't already join the co op http://www.digitalpoint.com/tools/ad-network/ Set up your ads to point to other pages within your site and not the index page. It worked great for me.
It's not a site I'm doing any SEO on. It's just a question that came up when I was searching for something which I knew was on his site, but I couldn't find it in google. The site URL is http://muad.xdev.net As far as I can see, the links a pretty much standard anchors. I thought that google would index the site regardless of how important it thought it was.
Wrong. And I see plenty of cached pages so they are in the index. My Box, gspTools and others are indexed.
Your friend needs to write unique page titles for each of his pages. I suspect this is why Google are not caching the content on pages other than the homepage.
I think Google has a limit on bare minimum ib's. The last I heard it was at least 2 or your site will not be indexed. Not sure if this rule is still in effect
