You don’t want to be lost in the shuffle of search engine results, but you also don’t want to pay for ads or other services that promise high rankings. A business directory list is an easy way to get more visibility online without spending a lot of money on advertising.
When you do a search, your results are based on what others have said about your goods and/or services on the internet. Search engines use links as one indication of relevancy because they know that reputable sites link back to other reputable sites all the time. They also know that local directories link back to other local directories frequently too! So if you want your website listed in multiple directories, this is definitely one way to do it!
