Google Launches Automatic Matching
Sunday, November 30th, 2008Google officially launched “automatic matching” for Google advertisers in November. According to the Google web site:
“Automatic matching is an optional feature that helps your ads reach targeted traffic missed by your keywords. It works by analyzing the ads, keywords, and landing pages in your ad group. It then shows your ads on search queries relevant to this information…Automatic matching won’t allow your spend to exceed your budget, and it also won’t affect the traffic you’re currently receiving.
This is an opt in system, as Google does not want to appear to be forcing, or ”tricking” customers into using this, which is a good thing. They seem to be using an algorithm to establish a pattern of words that are related to an advertisers key word bids and landing page to determine additional, semantic relationships related to an advertiser not using the exact key words selected.
So for advertisers looking to expand their reach, it appears to be an additional channel of traffic.
The concern I would have here is that it would effectively dilute an ad campaign.
Google claims to have a system to determine that only the high queries that yield a high click-through rate (CTR) and a cost-per-click (CPC) comparable to or better than an ad group’s current average CPC are executed on.
This however, does not say anything about conversion rates, which would be really the final factor in determining the success of the automatic matching feature. It puzzles me on this, as Google does have a “conversion optimizer” that tries to display ads based on a conversion level set by the advertiser. I don’t see anywhere that this integrates with the matching system. This means to me Google doesn’t have confidence on this system enough to put their money on the line.
Google also says they will not exceed the original daily budget set, so advertisers won’t get taken by surprise and have their budgets blown.
This has never usually been a problem for me, but there is one thing to note on this. Googles daily ad budget is really a “monthly” budget. For example, if you set your daily budget for $10 and there are 30 days in the month. Your budget really $300. So if Google serves $300 of ads in the first day, your budget has been blown and your ads stop.
I first learned this interpretation of daily budget when one day my daily budget was blown by alot. I called Google and asked about this, and the above is what they explained. Seemed “cheesy” to me, but at least now I know.
So am I going to try it? Likely not. It is hard enough trying to squeeze good conversion rates out of my current CPC terms and taking a chance on an aggressive algorithm determining my fate, seems to be a costly path.
It might work for businesses who can tolerate lower conversion rates, or for businesses who just want eyeballs, there aren’t too many out there like that, but there are always “suckers” :-)
