Since one of the important "counters" in gaining search engine visibility is how many other sites link into yours, you can help yourself (and eBid) by creating feeder sites into your shops, profile, favourite listings, etc. If you choose one of the sites that lets you create a web site and host it with them for free, all it will take is a little time and imagination.
If you have a favourite free hosting/building service, please share it here so that as many as possible can make the most of this useful gizmo.
I've recently been using webs.com (I won't make that an active link just in case, since it does offer a paid-for service too). It's easy to sign-up, just choose a user name (this becomes the key part of your web address) and an email address (hotmail works fine) and a few other trivial details, and away you go. There are lots of stylish free templates, and it's easy to build a site with a little content based around their suggestions.
For example, I registered http://sellonebid.webs.com/ with them and built that site (it's only got content in two pages so far, home & about) in about ten minutes.
So if you haven't yet tried anything like this, give it a go. And if you have, please share your favourite hosts and show off your results!
