Use Google webmaster tools & Google analytics to track web traffic, keywords, subscriptions and more.
Remember to create a links page on your website. The more people who you are linked to and the more who are linked back to you the better.
Sign up for Google Apps. I am cheap, I admit it. I used the free or standard edition because my organization is going to use less than 50 users. Here you will be able to set up email accounts with your domain address for example firstname.lastname@example.org instead of email@example.com For Windows Live users go here. Yola provides a great customer service page to set up your Windows Live account here. I have not used this product, I use Google, I have not had a problem with Google and I always recommend them first.
Your next step should be to set up you business Facebook page. Use your new Google Apps firstname.lastname@example.org email address to sign up. your Facebook user name should be your business name. Why use Facebook? Because that is where your customers are! Begin first with your profile, tell your customers what your business is about create an online portfolio of success and positive stories. Slowly you will build an online network of friends. Your local government has a presence here as well as you r chamber of commerce. Link to these people by becoming their friends. Are you having a sale? an event? create a fan page where you can ask for RSVP's or post special information about the event. As a business be very careful with how private your profile is, you will want more public access to find you. Update your Facebook page daily, the more traffic the better. This is true with all websites.
First why use Twitter? Twitter sends out brief notices to your followers. Many people follow Twitter on their mobile devices and Tweets tend to show up in Google searches quicker than a Facebook status message. Use a Twitter Clients that I mentioned in one of my earlier posts to post blog updates, TwitPics of merchandise, Shortend URL's of specials or listings. Twitter is a powerful tool and you will be amazed at how much traffic Twitter can bring to your website and hopefully to your cash register.
You should plan to use your website, Facebook page & Twitter as a team. One does not replace the other and each serves it own unique purpose. As you learn you can incorporate a MySpace page and other social networking sites specific to your organization.
Now that your on the web its time to get on the map. Two sites are here to help get you started. Yelp & Google places. I have seen the Google places sticker on multiple Rita's throughout the region. Google places has a great video on how the product works and you can view it on their page. Yelp by my own definition is the electronic yellow pages with reviews of businesses. I have used the site often and will continue to do so. I have found reviews to be very helpful and accurate. Yelp does have a help section for business owners to help you with questions you may have.
Finally create a linkedin professional profile to interact with other business profesionals in your field.
This is a process that is continually growing and evolving but will give you a good start. Yes this will seem overwhelming in the beginning but with patience & practice I hope your business grows.
