Perhaps you own a café or a spa, or you build swimming pools. It's not an online business, but you have a website that describes what you have to offer. You'd like more visibility for your site, and you've had a salesperson tell you about the benefits of buying a listing on her portal site. It sounds like a good deal, but how do you know? Here are a few tips that will help you make an informed decision.

Find out what's already working for you.

The first thing to do, if you haven't done it already, is to install Google Analytics on your site. Google Analytics is free and gives you important information about what is already working on your site - for example, which sites refer visitors to your site, and which keywords your visitors are searching on. Knowing exactly how many visits you get, and what those visitors are looking at on your site provides an important baseline to improve on. And, you may find some pleasant surprises - perhaps an article about your business or a site that you didn't know existed is referring important traffic to your site.

Installing Google Analytics is easy, but if you don't edit your own site, you can ask your hosting provider or web site designer to do it. For many sites, the installation takes less than 15 minutes.

Find out how highly the advertising site ranks.

Most potential customers will find your site by either searching on the name of your business, or by searching on keywords that describe your business. For example, they might search on "spas in phoenix" or "car detailing west hollywood". Run some test searches. In order to gain visibility for your site, the site from which you are considering buying advertising needs to rank highly for the keywords that apply to your business. If the portal you are considering doesn't show up on the first page, you probably won't gain much from advertising with them.

It's a good idea to get the specific page your ad will appear on. If your salesperson wants to sell you advertising on www.special_spas.com, ask the exact page that your listing will appear on, such as http://www.special_spas.com/newyork/dayspas.html. Then, make sure that this is the page that comes up for your desired keyword searches.

Another thing you can do is to check the "Page Rank" of the page. Page Rank is a measure of how Google's algorithms assess the importance of a page, on a scale of 0 to 10, with 10 indicating that the page is considered very important. You can see the page rank of every page you visit if you download and install the Google toolbar on your browser. Information about the toolbar and a free download is available at http://toolbar.google.com.

The most important point is that advertising space on a page that does not rank favorably may not provide much visibility to your business. Representatives from these sites may explain that they have a strong brand name and that thousands of visitors will see your listing. Fortunately, you can evaluate the traffic for yourself using Google Analytics (see next point).
