Fredrico, I take it you're new with Squidoo--so here's a tip that will help you a bit. First, determine what the main keyword phrase is that you hope searchers on Google will use to find your lens. Let's just say it is "trout fishing".
You should know that Google will only return two pages for any search from a top level domain. This means that if you do a search on "G" for "trout fishing" only two Squidoo lenses will show anywhere in the Google results. Try it, but trust me--that's the way it works.
So once you determine the keyword phrase (which will may be the name of the product you are promoting) do a Google search for that term and find the two Squidoo lenses that show. If they aren't anywhere on the first ten pages of results they won't be much competition so don't worry about them.
But suppose you find one lens on page 1 and one on page 3 of Google. Okay? Now, if you can't beat out one of these lenses for position in Google--it doesn't matter how good your lens is--it will never show on Google for that search term. So visit each lens, check the keyword density, the length of the copy on the lens, the LSI (if any) they incorporate, and--a biggie--keep your keyword density for your search term between 2.8-3.3%.
Your real competition is not only the number of competing pages returned by Google, it is the two lenses already showing on Google for that term. Ya gotta beat one of them out to get listed anywhere. Find out why they are listed and then beat the pants off of them! Good luck!
