When I'm doing keyword research, one of the first things I do is go on competitor websites and see if they have the meta keyword tag. If they do, then it instantly gives me access to all the keywords that they're targeting and allows me to work on beating them. Deleting your meta keyword tag prevents your competitors from doing this to you.

You can demote sitelinks so that they are less likely to appear but Google displays the pages that it considers to be most relevant to the searcher. Use the Mozbar to have a look at what the PA of the pages displayed are compared to the ones you want to display. You may need to have a look at your internal linking structure to improve the authority of the pages you want to display.

Thanks guys.

I suspected the profiles wouldn't be worth indexing, but it's always worth getting a 2nd opinion. Just annoying as the links are already there on good websites, but not offering any link juice. Nevermind.

Whilst looking for link opportunities, I have noticed that the website has a few profiles from suppliers or accredited organisations. However, a search form is required to access these pages and when I type cache:"webpage.com" the page is showing up as non-indexed.

These are good websites, not spammy directory sites, but is it worth trying to get Google to index the pages? If so, what is the best method to use?

For the most part, Google can crawl any links on the page, but I think I could do with a little bit more information about what pages are being linked to and how the links are being generated.

If you are using javascript or even (shudder!) Flash to generate the links then search engines will struggle to see them.

If it's in html then it should be fine, but you need to be careful of duplicate content. If a single page can be called up by multiple dynamically generated URLs then it can harm search ranking if rel=canonical tags have not been used.
