Adding your company and website information to high-ranking, popular online listing websites, including Google Places for Business, Bing Local, Manta, etc., can improve your online ranking. When search engines like Google see that reputable websites are linking back to your website, they'll assume that your website is popular, and may rank you higher.
Google Webmaster Tools helps Google crawl and index your site in their search database more efficiently, so that your site appears in search results quickly and correctly. Google Analytics allows you to see statistics about your website's visitors, such as what city they are visiting from, how long they're staying on your site, what they clicked on to get to your site, and much more. Read my blogs on Google Analytics and Google Webmaster Tools.
T. Brooks Web Design Online Listings
My website has been established for several years and has a high page rank due to a lot of traffic. Links that appear on high-ranking, popular websites carry more weight with search engines. When I add a Business Listings page for your company, the link from that page can make your website look more popular to search engines, which can help your site appear higher in search engine listings.
And if you don't have or want a website, your Business Listing can even serve as a one-page mobile-friendly website. You can even have your own domain name so nobody will know that the page resides in a subdirectory of my website. View some of my listings sites HERE, HERE and HERE.
