1 keyword or many keyword use for webpage

I have a blog and i creating a webpage for targeted keyword. My question is can i chose only 1 targeted keyword or more. What is the best practice.

 

I think it's better to tag a couple, but not too many because then google thinks it unnatural. I've read somewhere that from 3-5 is best - but I can't tell you how accurate that is, it's all just some man's opinion

Also does anyone know if it's better to tag many posts with the same key word - for example if I have 20 posts about a specific Internet Marketing area but then I tag them all with "Internet Marketing" will it help? or just be like keyword spamming?

 

I think it better to use more than one keyword to make it look more natural when doing link building.

 

Add more than one keyword if it appears that you are likely to benefit from them.

 

3 keywords per webpage are best.

 

I think you should use 3 or 4 keywords for your web page promotion. But remember one things these all keywords are closer to each other, means high keyword proximity. Because if your keywords are closer to each other then they are very easily get visitors.

For example if your keyword is chocolate. Then your should choose keyword like Dark chocolate, chocolate gifts, chocolate cookies. By this your main keywords chocolate is targeted in all sub keywords. So more than one keywords are better than single one.
