*Sub-domains as Portal Sites* One of best uses of sub-domains is portal websites. Portal websites are sites that link to your main website and have a similar theme. Basically, they provide another portal, or doorway, for visitors and search engines to get to your main website.

Since creating content for a website takes time, often webmasters simply modify existing text of main site and reuse it on portal site. It is important that content is not exactly same and portals do not just redirect to main site. Otherwise, search engines may not index them.

*More Portals, More Visitors* Portal websites can be submitted to search engines just like your main site. If your website is doing alright in search engines, then imagine having five more websites out there for spiders to find. Five more listings means that Web surfers have five times as many ways to find your network of websites.

Why not make sure web site you use works as hard as you do to establish credibility? Let's look at elements that can be built into a well designed web site to enhance credibility in eyes of your potential customers.

1. Offer A Guarantee Nothing beats a solid, believable guarantee for building credibility online. It may be hard to believe but buying via Internet is still unfamiliar, and uncomfortable, territory for majority of people. It is up to you, business owner, to put their minds at ease.

One way to do this would be to offer an unconditional, 100% money back guarantee. Include cost of shipping and handling in your guarantee. By assuming all of risk, you will earn instant credibility points with most potential customers.

2. Provide Contact Information Even best guarantee won't help establish credibility if potential customer can not contact you. Post accurate contact information on your web site and make it easy to find. Provide as many methods of contact as possible, do not simply post a link to an email address.

For maximum credibility, post complete mailing address, phone number (preferably a toll free number), and email addresses for customer's to use if they feel need to contact you.

3. Use Testimonials Testimonials are Internet equivalent of word of mouth advertising. They can be very effective tools for building credibility provided they are believable. To get quality testimonials, ask your past customers for their opinions.

Obtain their permission to use their word and names as part of your advertising. Do not use celebrity endorsements, most people assume these are paid endorsements.
