This is One of the biggest problems when trying to Make Money on the Internet.
No matter what you are trying to sell or promote, you need to be visable. There are the old standby's of using various Feeds such as FeedBurner, Technorati, Postami for Blogs. There are also some RSS feeders that I have mentioned in previous posts.
There are a couple of other ways to get your site seen by interested parties.
If you read a few different Blogs or Websites throughout the day, leave Pertinent Comments to on their posts. Don't try to Sell yourself or your product, just leave a Good Comment. All of the Sites I have visited have a place for your E-Mail and URL addresses.
Another place to go is to some type of Forum, you probably read them to get info anyway. Join the Forum(s) that are related to your Site in some way. They all have a Signature section, that's where you put Your Link. Join in the conversations, ask questions, answer questions. A Lot of people (myself included) will try the links for additional information.
Whatever you do, Don't SPAM the Site, in other words, Don't put a Bunch of Unnecessary Links in the Comments. Let your Ideas speak for themselves.
If you have any Additonal Suggestions, Use the Comment Section. If you were on the new Home Page and got transferred here through a link in an article, Please Click Here to Return to Working at Home on the Internet (the New and Improved Version).
