Hi, I want to know that how could I check keyword density of my competitors?? Does it effect in page rank and search rank??? Does it effect in url as it affects in title, keywords, description and content???
there are many tools online you can use just google'keyword density tool" and choose whichever you like
Personally I think it's a waste of time to worry about keyword density. You can go check your competitor's keyword density, but what does that really tell you? Do you really think they have those rankings based on keyword density? Of course not. They have those rankings based mostly on backlinks. Instead of obsessing over keyword density, just write for your visitors and include keywords where it makes sense. If it sounds spammy or awkward to read you have over optimized it.
why would you waste your time looking at the keyword density of you competitor?... I think its just a waste of time, it is better if you try to optimized your site more than your competitor, play with your keywords, I'm sure you'll get a good result on it...
