Manage the retail way
The primary advantage of shopping campaigns is that you can manage in a retail-centric way. What does this mean? Picture a supermarket. The same way they showcase their best products at the front of the store in order to maximise sales, you can place your best sellers into their own product groups based upon their performance.
In addition, you can bid differently on different products to attract more visibility for the ads you want people to click right when they are ready to buy.
Report on your product attributes
With a new campaign type comes new and improved reporting. The reporting features in shopping campaigns allow you to view essential performance data for any product attribute you can possibly think of. No matter how you classify your products in AdWords, you can run reports to glean how well your PLAs are performing, based upon size, SKU, colour, etc.
Track your competitors at every turn
Wouldn't it be great if you could track how well your competitors' PLAs are performing? Shopping campaigns allow you to easily see the benchmark data, CPC and CTR of other advertisers for similar products so you can figure out how to outshine your competitors.
Peak into the future
Let's say you were running a campaign and were contemplating changing your bid for a specific product group. If you didn't actually change your bids, you would have no way of knowing whether you missed out on clicks or impressions, right? Wrong.
The bid simulator is a tool in shopping campaigns that will help you estimate the performance you would have received for your PLAs had you gone ahead and changed your bid. Google uses this example to better explain the benefits of this tool: Suppose you have a maximum CPC bid of $1 for your product group, but you're curious to see what results you'd get with a bid of $1.50 or $0.75. The bid simulator can show you estimates of the clicks, cost, and impressions, you would have seen with these other bids. You can also change your bid and apply to your product group.
This data can help you find the optimal bid for campaigns, providing a clear picture for your strategy.
