We presume you have gone to Google, entered either your keywords or indeed your website address and you don't show up in the search results.
So, the first question would be, what are you searching for in Google?
If you are searching for a product or service that you sell or provide then it is likely you wouldn't be at the top of Google (unless you have been trading online for a number of years or run some kind of Ad Word campaign), instead, try this:
Check for your index status: Enter your website into Google like this: site:www.yourwebsite.co.uk and press search. If you see pages from your website listed then Google certainly know about your website, however, there may be underlying issues to do with your actual website itself. This could possibly be low keyword relevancy of your website content.
If you see nothing listed then there could be a number of reasons for this.
Here are some checks you should do:
Have you even submitted your website to Google?
Do you have a robots.txt file? if so, is this preventing indexing?
Is it likely your website has been banned from Google's indexes?
