I've been doing some research on how to effectively structure our meta description. Snooping around on WebmasterWorld I’ve come to the conclusion that if used correctly the meta description can be a valuable tool. While there are some discrepancies on how each SE uses the description, i will be focusing on using the description to `bait` to bring the users in.

My challenge is how to make this work effectively. Since i run online store i could take my products description and just toss it in the meta description - although since our product descriptions vary significantly, i can't be assured that using the product description will help provide any good information in a short sentence.
So here's my question, what do you think would be the most effective way to structure a description based on the fact i am promoting a product `Purple Widget`?

1.) Information and resources for `Purple Widget`

2.) `Purple Widget` and related information

3.) Looking for `Purple Widget`? Find information and products at `Company Name`.

Sample 1 presents the user with the obvious. Since all we know is the user searched for `Purple Widget` we can safely assume that they're looking for related information. I'm attempting to keep the keyword as close to the beginning of the sentence without actually having it be a first word. Keep in mind my page titles will also be `Purple Widget` so it could look spammy having the page title and product description start off with the same words.

Sample 2 could should catch peoples eyes quickly since it provides them with the keyword right off the bat. It's short and sweet, but is it effective?

Sample 3 attempts to ask the user a question, from what I’ve - asking a question (albeit rhetorical) can be good `bait`.
So this leads to the next logical question, which sample do you prefer and why?
