Choosing to bid on the right keywords can be key to your pay per click success. By choosing the proper keywords - words that your potential customers would use to search for your product - you can pre-qualify web traffic and skyrocket your conversion rate.

But how do you choose the right keywords? Here are 3 powerful tips to uncovering profit-pulling keywords for your pay per click campaign.

#1) Choose Relevant Keywords

While this SEEMS obvious, you'd be surprised at how many ppc campaigns bid on unrelated keywords (Their logic might have a foundation but we just can't see it from a searcher's point of view).

So for example if you're selling an e-book on how to make money buying foreclosures, don't bid on keywords related to stock trading. Yes, these both have 'money' in common but that is a WIDE net to cast - and a huge waste of your money.

Even when you bid on a keyword - make sure the description not only fits the keyword but matches what the searcher will find when they click on your ad. Nothing ticks internet searchers off more than misleading ads.

You'll not only NOT make the sale - but you'll be making a non-customer for life, even IF they would have eventually bought your product.

#2) Choose Lots of Low-Cost Keywords

Unless you're Weight Watchers or Jenny Craig, chances are you can't afford to spend $5.00 on the keyword 'diet'. That's ok, you don't have to.

Think niche with your keywords and you'll find lots of low-cost related keywords - sometimes with absolutely no competition.

Now obviously these keywords are low cost because there are not a lot of searches on them (say 50-100 searches per month). But if you bid on a LOT of these keywords (say 200-300) that adds up to a lot of CHEAP traffic over time:

100 searches x 300 keywords = 30,000 searches and possible hits a month.

How do you find these low-cost keywords?

Use the keyword selection tool provided by most ppc engines to look up a main keyword. Then start from the bottom up to pick out related, low volume (less than 1000 searches a month) keywords.

Also, don't forget to use misspellings. So many people don't bid on misspellings that you can usually top positions quite cheap.

#3) Use Your Keywords In Your Title or Your Description or Both

Using your keyword in the description can double your click throughs, which means more interested prospects visiting your website.

You want the visitor to click on your link, only if they are really interested. Including your keyword in the title or description is a great way to weed out the tire-kickers from the sincere customers.

It reinforces the idea that YOUR website can give them what they are searching for - a sort of mirroring back what they typed, which breeds trust and likeability.

So those are several tips to helping you choose the right keywords for your pay per click campaign. Good luck and may your traffic (and sales) increase exponentially!
