how many keywords vl u suggest to place in any site?is their any limit?will more number of keywords cause any harm?
I would suggest putting at the maximum 30 keywords in to your meta tag if thats what you mean. This is because the more focused keywords will lose its importance with the more keywords you add. If you are on about through out a websites content, then i would not say there is a maximum however try and concentrate most of your attention to a certain few, perhaps 5-10 keywords. Will.
