Local Ranking Factors That Can be Useful For Your Local Business' SEO

As a small business owner, you understand that running your own shop can be a struggle at times. How does a local coffee shop compete with coffee giants like Dunkin’ Donuts and Starbucks? How can a cafe rival Panera Bread and Corner Bakery?

Through grit, determination, and local SEO.

You have the grit and determination down pat, but local SEO? What’s that?

It’s a way to help current and potential customers to find information about you online—and then patronize your business.

The What and Why of Local SEO


SEO is “search engine optimization,” a practice that is meant to help grow your company’s visibility through organic (or non-paid) research. Local SEO focuses on optimize local search, meaning they focus only on ranking in the specific geographic area in which they conduct business. This type of internet marketing helps current and potential customers find information about local businesses online. Local SEO helps:
● Make sure your business details (name, address, phone number) are correct
● Build your client base through other customers’ reviews
● Provide current and potential customers convenience
● Push your business’ visibility ahead of competitors

Considering that about 64% of local customers utilize the Internet to find information about local businesses and 78% of online mobile searches result in a purchase offline, local SEO has become more important than ever.

Ranking Factors for Local SEO


Ranking ahead of other local competitors is going to take some work. Here are some of the top ways to make sure that you rank ahead of your competitors.


# 1. Utilize Online Local Directories

Directories like Yellow Pages, Whitepages, Superpages, and Dex Media are a great place to start. Make a list of online business directories that you want to optimize. This list will be long, as you want to target every possible listing site that a potential customer may visit. Once you have your list, go through each and make sure that your information is correct; if not, go through the information and update it. This information should be consistent across all platforms. If any information changes in the future, such as location or phone number, update it immediately.

# 2. Claim Your Pages Online

Search engines Google and Bing offer their own type of online directory by providing listings for almost any business. These pages—Google My Business and Bing Places—can help you rank high in local searches. Claim your page now so your listing is accurate when people search for your business or similar business. Benefits of these online listings include:
● Provide information about specials or in-store offers
● Add photos of menu, menu options, interior, and more
● Respond to customer reviews
● Gain insight into how customers look for your business

You’ll want to claim as many of these online listings as possible to target all current and potential customers no matter where (or how) they search.

# 3. Write Localized Headlines and Content

If you have a business website (and you should!), you’ll want to write localized headlines and content for each page. Writing localized headlines means you include the city and state in an article’s title. A coffee shop may have a headline that reads, “Cuppa Joe’s CafĂ© in San Bernardino, California.”

The same applies to your content: You’ll want to include at least one mention of your city and stop in proximity to your business name or details of your business (clothing boutique, coffee shop, spa). Don’t over-saturate your content by constantly referencing your business’s location. A handful of times will do.

2. On the next screen, you will see the license agreement documentation. After reading the license agreement carefully, select the option "I accept the terms in the license agreement" then go on next.


3. After accepting the license agreement, you have to fill-up some server information on the as given on the following screenshot. Give some network domain name and server name as given on the example, if you don't have, you can also write "localhost" on both fields. Write any email address on administrator email address field then select on the option for installing Apache HTTP server programs and shortcuts for All users, on port 80, as a service and go to the next wizard.

On the "Typical" option most of the default program features will be installed without installing headers and libraries for compiling modules. The next option "Custom" will allows you to choose which program features you want installed and where they will be installed. I would recommend to select the Typical installation option at this time.
