Well I've read a lot of topic that say that: "sites with competitive keywords will get in the sandbox for those keywords" , and , I know it might be a silly question , but I was wondering what makes a competitive keyword a competitive keyword? .Competitive = lots of traffic , lost of searches , high CPC ? What are the limits ? When does keyword A becomes competitive . What makes keyword A more competitive then keyword B ? I hope this makes sense for you people .
It's fairly safe to assume that any keyword worth targeting will be sandboxed. I've yet to see any competitive well trafficed keywords that it's easy to rank for initially.
Well, what I wanted to find out is actually : When is a keyword worth targeting ? Is it about 100k searches a month , big advertiser bids , both combined or what ? I'm afraid actually no one but Google knows the answer to that .
Personally I look at the number of searches per month, I tend to actively target anything above 100 searches, though that depends on the market.
