Let's use this thread to discuss these resources: Hubpages, Squidoo and Zimbio.

Both Hub and Squidoo use "tag pages". These are pages that contain links to hubs/lenses that use the same tags (keywords).

Some of these pages have pretty good PR. Your goal is to get your hubs/lenses on as many of these pages as possible.

Not only for the link juice (if any), but we also want to find these tag pages that are already appearing in Google SERPs so they can drive traffic directly to our hubs/lenses.

And, we will also get links from all the other hubs/lenses that share the same tags, which can send some traffic our way.

We'll want to find as many relevant tags as possible and use as many of them on our own hubs/lenses as we can. Both Hub and Squidoo have limits to the number of tags, so just create multiple hubs/lenses, making sure you use every possible tag at least once.

To find tag pages that are indexed by Google, just use these custom searches in Google:
site:www.squidoo.com "Squidoo : Tags" las vegas
site:hubpages.com las vegas "Hot Hubs"

Just substitute "las vegas" with your own keyword(s).

Now "extract" the tags and add them to your hubs/lenses.
