Welcome to the Q&A Forum

Do you find the search optimized press release sent through PRWEB are effective?

I'm not sure. It was the first thing that popped to my mind. I'd have to spend some time googling it though as I've never actually done this.

Can't you configure your server to point to the hosted wordpress blog from inside a directory?

This was the approach we were considering. However, what gave me pause was looking at other social networks are doing.

• LinkedIn only has 50k profiles.
• Meez has multiple index files and looks like they are indexing many of their profiles
• Facebook and MySpace don't appear to use Sitemaps (although they do have a crawlable member directory)
• WeeWorld has 500 links

The point is there doesn't seem to be any consistency.

If we end up creating a human readable directory ala Facebook does that achieve the same thing?

Yes, we have the concept of public / private profiles. Private profiles aren't included in the index.

We're working on some changes to our site and want to add a site map file to give some hints to search engines on our member profiles. Our site has millions of member profiles. I want to ensure that Google indexes them.

Is there a benefit to submitting millions of profiles across multiple site maps?

Is it better to pick a sample of those and submit them? Most member profiles have links to other member profiles.

Is there any benefit to taking a single site map of 50k links and then changing it at some frequency so that all of the member profiles are eventually indexed?

Thanks.

I'm in the process of adding some new features to our site and have a question about our URLs.

Most of our URLs consist of either

sitename.com/contentname or

sitename.com/content/contentid

I'm in the process of building a directory to those pages. The directory has a number of filters which will ultimately point to the destination page.

sitename.com/filter1/filter2/contentid or

sitename.com/filter1/filter2/contentname

The destinations will have references.

From an SEO perspective, I would think I want the filter1/filter2 version of the link indexed since this will add keywords that someone might search for. However, since the filters are dynamic, if someone just searches for contentname I would want to have sitename.com/contentname returned in the search results.

Do I get any SEO benefit out of building those filter links as described if they are not the canonical links?
