Been messing around with replacing generic product descriptions into an image file. I'm thinking that this will also wash out all those generic words that I don't necessarily want to rank for while increasing the ratio of ones I do. Your honest opinions are appreciated.
You just shoot yourself in the foot doing this.
It won't help your SEO in any way - Google won't be able to read the image [or text within it]. Additionally, if you wanted to change a text slightly, you would have to edit the image and upload it again to all products. People often browse websites with images switched off so they won't be able to access vital info on your pages. Just. Don't Do. It.
