So, what is GSP? The service quietly launched three years ago, with Google soft-selling the ads rather than going full-out to promote them. Now, however, word has spread among advertisers that the ads are effective, and more people want "in."

In order to achieve your own marketing goals on GSP, you need a plan. Here'show to get started on the systemand drive marketing results using Gmail Sponsored Promotions:

About Gmail-sponsored promotions

Gmail Sponsored Promotions are advertisements that appear on users' Gmail account in their inbox and above their email. Once users click on an email, it expands into an ad, complete with images. Ads appear only on free Gmail accounts; business accounts, which are a paid service, are advertising free.

Gmail's new tab-sorting method places its own advertisements into the "Promotions" tab on the Gmail system. Since the Gmail system is notorious for misclassifying emails into the wrong categories, a lot of legitimate and necessary email gets dumped into the Promotions tab, too. As a result, users are still likely to look through their Promotions folder from time to time.

How much does GSP cost?

The system runs on the typical cost-per-click (CPC) methodology you're probably familiar with from running Google AdWords or other digital campaigns. You set your own budget by establishing an account and bidding on the CPC by keyword.

However, GSP counts any interaction with the ad as a click and dings your account balance accordingly. Even if your cost-per-click doesn't bring a user to your website, the cost to open the email is still deducted from your advertising balance."

Driving marketing results with GSP

There are three ways in which GSP excels at helping marketers achieve their goals:

1. Targeting competitors

GSP offers an intriguing advantage over other forms of CPC advertising, in thatGoogle crawls users' Gmail accounts anonymouslyand compiles information that's beneficial for advertisers. This information can be used strategically to target your competitors' customers via GSP advertising.

By building GSP campaigns around competitors' keywords, you can target customers who are seeking information on your competitors' products and services. Instead of seeing advertisements from them, they'll see your ads in the GSP box.

2. Building awareness

GSP doesn't work like a simple direct-response digital ad, since users must click twice, rather than once, for the ad to bring them to your website. Although you can still build a direct-response component into your advertising (see number 3, below), it's not the most cost-effective direct response mechanism out there.

Instead, think of GSP as an awareness-building campaign. You're getting your products and services directly in front of customers while their attention is focused on the screen. As occurs with any awareness-building method of advertising, the more exposures to the ad, the better. The longer you can run campaigns, the more benefit you'll derive from an awareness and exposure ad campaign.

3. Increasing email acquisitions

Here's where GSP can be used as a direct-response tool. Use the ads to boost your email list and acquire names, ethically and legally. Because GSP is a two-click response, you will have gotten past the first hurdle by getting customers to open the email.

It may be difficult to get them to click on a product and buy it just from the ad in the email, but it's a lot easier to get them to enter their email address, check an opt-in box and ask to be included in your email list for a promotional discount, a free download or some other gift.

At that point, if you've set up your opt-in correctly, you will have acquired a new address for your email list, and that can be worth its weight in marketing gold if you've got a strong autoresponder going. Cultivate that lead along the pipeline from awareness to sale -- and your GSP ad campaign will have just paid for itself.

Exact targeting with Google's powerful analytics

LIke its cousin Google AdWords, Gmail Sponsored Promotions uses Google's data to help advertisers target customers better. This includes selecting audiences based on display keyword, advertiser customer match, locations, languages spoken and demographics.

Also similar to what happens with AdWords are theindustries which are excluded from the ad campaigns. Advertisements for weight-loss products, funeral services, gambling and so on cannot be displayed. GSP follows theAdWords restriction guidelines, so if you follow those, you'll be set on GSP, too.

If you haven't tried Gmail Sponsored Promotions yet, know this: They're a good way to drive marketing results, if the results you wish to achieve fall into the "awareness" or "certain acquisition" categories. Ultimately, they're another way to collect data on your ad campaigns, monitor keyword effectiveness and add to your email list.
