Starting a New Business is not an easy task as it’s always difficult to get traffic and if your plan is to sell your product or services then it’s more difficult to get targeted traffic. Lets take an example which clears you the importance of local traffic.
Lets say you are selling SEO services in Los Angeles region and wants clients from Los Angeles only, now you can’t stop visitors from rest of the world to browse your website. But your main target is to get as many traffic as you can from Los Angeles, client from Florida is not as much important as the client from Los Angeles (as your key market is Los Angeles not Florida). In order to get more and more traffic from Los Angeles based client it’s important for your business to get listed in all local directories. As many visitors search from these directories and you can get business by listing your business. Many places are there to list your Business but Google Maps, Yahoo Maps, Bing Maps and Some Local Directories are more important and you must go for it. Another main reason is all 3 major search engines starts showing maps in searches which makes it more importance to get listed in it. Check below image for more details:
This is what Google search shows if someone searches for “SEO Services, Los Angeles” in Google.com. It’s not important that your business starts chowing in Google.com first page listing as it depends on lots of other thing also but if you don’t claim your business do it now as sooner or later when your website grows rankings or listings keeps on increasing.
