I have written code that will detect when a user is a search engine and i dont include css files when this happens to save bandwidth. I was also thinking i could replace ALL images on the page with a 1px placeholder. Is this an ok thing to do?
Search engine bots cant see what the image contains so there is no need to be loading large images when the bot cant even view them. If i replace with a 1px image it will hugely increase load speed since i have an image intensive website.
