What is the local traffic? One day is not a large amount of time.

Check if your Searches# is "Broad" or "Exact". You may get a Global Searches of 20k for "Broad" but only a few hundreds in "Exact" for some keywords.

Additionally, your SERP may be dancing but it wasn't reflected in your Google search. Try Scroogle to check where you rank.

Hope that helps!

As stated, make sure it is an exact search and not broad...This will make a significant difference in the search volume during keyword research. Also, give it some time. It could be a fairly low exact search that only gets 250 searches a month. Now, In second position (and not even first), will you receive 100% of the traffic searching the keyword.

On average for this example that would come out to 8.3 hits to your site each day at 100% traffic. Say second rank in google receives 25% of traffic. This would come out to 2.1 clicks to the site for that keyword each day.

Try giving it some time and see if it works out for you.

20th December? Its just one day... Be patient.

Its just 4-5 hours that your website is ranking one... Let people search your keywords and your traffic may rise in few hours.

What does webmaster tools say about the number of impressions you are receiving on that keyword? If you are not seeing impressions you are not going to see traffic.

Google based search results based on your history so you need to double check and make sure you ranking is where you think it is.

Try to wait for days. 1 day is not enough to observe traffic.

Sounds like you might be looking at "broad" not "exact"

use google keyword tool and on the left hand side you will see check boxes for broad and exact. Click exact and see if it updates with different search results.

This is quite a common mistake by people when searching for a niche.

I think your offered some offers like discount on your services, product and other.
update your news feed sections.

It really depends on the keyword. Is it a long tail KW? Also, Google Keyword Tool can be off sometimes.
