Everyone has this fear once in a while. There is something you can do about it. You can make a difference in the way your site comes up. There was a time when it was 20% skill and 80% black magic but those days are days are gone. If you just follow some rules and make it your weekly task to post something to your web site you can move your site to the front page of the search engines and get more clicks. More click gets you higher in the rankings and you get more visitors and away you go.
But things have also changed in the way Google looks at things. Because of the changes that Google has made you will need to put new content up on the web to stay up on the ranking. It is something that just needs to be done. This is my Show Computer Therapy. I was alone that this day and just talked about what you can do to make your site work for you.
