There are many advantages of online business directories and local business listings sites for small businesses owners, such as:

Business Directories are Cost Effective
There are many online advertising sources out there, which cost hundreds of $$. But many of online business directories for which listing your local business is free, and some listing sites (such as Local Data Biz) require additional cost for some special features, such as more than one business listings, multiple locations, multiple categories, location map, a website link, or adding videos and photos.

Increase in Local Visibility
However online business directories are enormous, they have suggesting capabilities and advanced filtering, and help you to connect with your targeted customers or audiences. For web designing companies and other small local business, online directories are truly beneficial because they build your business locally visible to your community.

Help to Get Found More
Usually local business listing sites and directory allows their users to search by specific basis, such as location, category and service. This is extremely advantageous for small businesses, because sometimes, users don’t know to search the specific service or a specific business name they need. If you added complete information about your business in your local listing, than chance are high that the directory will show your business to user even if they don’t search about your business.

Improve Your Business Reputation
Online business directories allow user to give reviews about their local businesses. This will help small businesses to improve their reputation by getting positive reviews. There’s also a chance for negative reviews but if businesses owners know how to properly handle user’s reviews, than weigh of negative reviews will be decrease. Also remember that negative reviews are not so bad for your business reputation, because a blend of positive and negative reviews shows users that you are perfect and trusted organization which has nothing to hide.

Strengthen SEO
This one, as a SEO specialist, I like the most. For search engine optimization (SEO) Google and other search engines are always looking for user’s trusted businesses, so if you provide complete and accurate details about your business, same as you provide on your website and on google my business listing, than chance are high to rank higher in search engines.
