I have a website that I recently built. I have one concern with how I did the keywords to get it to the 3-4% ratio margin. My website really has no purpose besides to give the company I am trying to get off the ground a site. My main focus is sales of merchandise like Target. Since all my items are on my ecommerce site search engine visibility would not recognize them. I created a txt file and hid it from mobile and threw it under the background of my website. I had all of my keywords 50-150 times written in the txt. The only words in the txt file are my keywords. I have seen that search engines are supposed to fairly good at spot something like this. I was wondering if anybody knows how bad this could be and if I should eliminate it or if I created the txt file with 1000s of words and wrote a story with the keywords in it, would that work. Any information and suggestions would be much appreciated. Also any proven free software of paid software with testing period for building backlinks and generating links would be much appreciated.
