Possibly a stupid question about content

So, let's say I have a site I'm aiming for the keyword "advantages of an iPhone".

Would it be bad if around half of my articles didn't have this keyword, let's say they only has the keyword "iPhone" mentioned.

The reason why in asking is because I've a site that gives information on a certain subject and I always target specific keywords. But I'm letting others give me an article about their experiences with this product (which I'll be getting for free!). So they might mention the product in the piece but they won't specifically use my keyword. Is this bad for SEO ?

Thanks

might not be

I would not be concerned as log as the content is relevant. I try to make sure articles include all top LSI words more than stuffing the main kw. Free user provided content is nice as long as it is unique and not scraped garbage.

No it wont hurt you. As long your tags and other articles have good keyword desintivity and you get backlinks with proper anchor test.

Nice one thanks guys.

I think I've found a way of getting people to do some content for me for free so I can't really complain.

Hi I think Google is much smarter than that. They are able to see that the articles are relevant even if you do not have the keword, but other words are in 1st degree or 2nd degree connection with your keyword so Google knows it is relevant article. I think even if they don't have iPhone at all could even be no issue.

For example look if I google "iphone" then the related searches are:

Searches related to iPhone

iphone tmobile

iphone verizon

iphone sprint

iphone at&t

iphone 4g release date

iphone apps

iphone review

iphone 4g


Then if I google "iphone 4g" the related searches are:
Searches related to iphone 4g

iphone 4g release date

iphone verizon

iphone 3gs

iphone 4g price

iphone 4g gizmodo

iphone 4g release date 2010

apple

ipad


so this means as far as I know that if your articles are talking about apple or ipad and have nothing at all about iphone then they will still be considered relevant content.

i hope i have helped
best of luck
