So you're asking, what are portal sites, and what is it that they can do for me? A portal site is a website that doesn't really sell anything, but there is tons of information, and links to other sites on them. There are usually ads all over these sites, as this is usually how these sites make their money.

Portal sites can help you, because by determining how many portal sites there are in any given market, one can decide if it is indeed a good market to get into or not.

You can see, that by checking out these portal sites' alexa ratings, that they are getting just tons of traffic. Which is always good, especially if you would like to place a banner or ad on one of their websites. As this will link others to your website. It is important to remember that these portal sites are not competitors, but really just portals, or doorways, if you will, allowing more traffic to come to your site. Portal sites are great at getting search engine traffic, and can potentially promote your site if you advertise with them. You will have to pay them to promote you, and there are many ways that this can be done. You can offer content for their site, you could let them join your affilliate program, or just pay them for a banner space. In any case, portal sites are ideal for boosting traffic to your own site.

If, on the other hand, you are just looking for a good market to get into, you can do a search on any search engine for keywords in your market, and if a lot of portal sites come up, then you can be reasonably sure that it is a good market to get into.

My new website is a portal site. There are links to sites that offer not only website developement tools, but personal developement tools as well. Hopefully, my new website will soon have as much traffic as those other sites out there! May we all succeed at health, wealth, and happiness.
