Although Google Base is similar to Google Search, it is not the same thing. Google Base is a way for you to submit specific types of content to Google. You also do not need a website to submit your content.
Popular types of content include:
Events and activities
Depending on the type of content you submit, your item may not only show up through Google's search, it may also show in places like Google Product Search.
The first step to getting started is to sign up for a Google account which is free. Once you have signed up for your account, visit the Google Base website.
Read the terms and conditions for submissions, as well as the section on Basics. It will only take you a few minutes, but it is well worth it because you want to create content Google likes and does well in search.
You have two choices when you submit your content: you may submit one item at a time, or you may submit more than ten. If you plan to submit more than ten, then you need to create a datafeed. (Google shows you what you need to include in your datafeed and how to set it up.)
The next step is to sign into your account and then begin posting your items. If you are submitting one item at a time, you first choose the type of content you want to submit. If the content type is not listed, you may create your own category for your content.
When you are choosing your content type, you will also want to choose the country. This is especially important if you are selling something locally, or you need to target a specific country with your offering.
Completely fill in the information on the form. Depending on the type of content you are submitting, it will determine what you need to fill in the form. Write a good descriptive title of your content, and make sure you include any relevant information in your listing as well as a link if you have one.
Google offers a convenient HTML editor to help you write your listing, so you do not need to know HTML to create your listing.
You may attach up to 15 different files to your entry. This allows you to include different types of files, such as Word documents and spreadsheets.
Your entry is not live until you publish it, so make sure you click the publish button when you are finished.
The important thing to remember here is to follow Google's rules. You do not want to spam this site. Otherwise you will get banned. Follow the rules and Google will not only promote you in their search engine, but in their other sites, like Product Search, as well.
