There are 11 Advertisers who are paying Google for sponsored listing for the keyword "Leasing A Car". I laugh on them as whenever they stop paying Google they will lose their position and they are paying approximately $4/visitor to their website.
I'm laughing at this comment!
First of all, not all advertisers are paying $4/click. The
average CPC for that phrase is $2.81 in the US. Do you know what those advertisers' ROI and conversion rate is? Let's say I'm paying $4/click and have a 5% conversion rate. If the average value of a customer
is more than $80 , I'm making a profit.
And where did you get the "more than $10,000/month" budget figure (which they may have, but I guarantee they're not spending that on that one keyword) or the figures to back your statement that they could get to the top of the page organically in 3-4 months?
They can't ALL get to the top of the page and there are only 10 spots on p1.
Furthermore - Looking at the search results for that phrase, there are 3 Adwords ads at the top, followed by 2 Youtube videos and just ONE organic website result showing "above the fold" (as opposed to a total of 10 Adwords ads.) Which has better visibility?
If I change that to the more action-oriented phrase "Lease a Car" (which would probably catch your audience a little farther along in the purchasing cycle), there are now several local results (Google Places, which is now part of Google +) competing for the top-of-page real-estate and pushing the global/organic results down even further.
This is a question without an answer. SEO tactics, Social marketing, PPC, Local search, media buys, offline marketing, etc - they're all tools. You use whatever combination of tools is most appropriate for your particular situation.
