Too many keywords in the URL can be a problem

I would not indicate any revolutionary fact, but if natrpate in a URL or a bunch of too many keywords as possible that you designate Google as a spammer, or at least drop the page from the index. I do not believe that this is something which we have much to fear, but it should definitely pay attention to the logic when creating the structure of URLs. As you can overdo it too often with the use of certain keywords on the page so you can overdo it with the very URLom says Google :

Now I'm all for having descriptive URLs, but .... this seems to be taking it a bit too far and I have a bit of trouble identifying anything that matches in the content of your page.

You can read the examples on the above link it specifically considered overkill. As an illustrative example, the URL contains a considerable number of keywords and their variations. These are quite general keywords in the URL and immediately gets the impression that someone is trying to take the extreme factor. And losing the context of the URL because it includes too much.

Any kind of hyperbole can be a problem, it's not just a matter of URLs or other factors. Everything that works best is to do without overdoing it. All one can safely do in a very logical way for visitors in accordance with the rules of search engines.
