In a recent Search Engine Land opinion piece entitled Automated Keyword Bidding? More Like Automated Money Sink, the author espouses the view that automated keyword bidding is flawed because it is impossible for agencies to scale their systems to deliver positive results to clients.
While I agree with most of the points the author has raised, I believe his conclusion is wrong. Blaming automation for poor bid management is the equivalent of blaming a Ferrari for a car crash if a monkey was driving it.
The real debate is really optimization vs. automation. Many people confuse the two and perhaps it needs clarification. Rules-based bidding is sub-optimal and not a scalable solution for clients.
Rules in computer science are known as “heuristics” and are defined as rules of thumb that do not guarantee the best solution. However, a bid optimization algorithm does guarantee the best solution subject to the constraints applied – i.e. a spending target or a CPA/ROI goal.
There is also the issue that keyword performance based on 7 day or 30 day increments can lead to poor campaign management decisions. I agree with the author on this point. The flaw is that the marketplace is very complex and doesn’t account for factors such as news, seasonality or events making it impossible for a human to correctly figure out what bid would result in specific CPCs , ROI and position.
Simple curve fitting (i.e. what a smart high school student would do) will simply not work. Bid performance profiles for keywords can be vastly different. Keyword models themselves need to be sophisticated and require knowledge of techniques such as time series forecasting. Crunching this large amount of data needs a huge database and computational firepower. An excel spreadsheet will not do. However, the flaw here is not of automation but that of building poor keyword models.
Instead of avoiding firms that espouse “proprietary technology”, it’s better to ask the right questions to make sure they truly understand optimization. Some important questions to ask include:
It is not automation that should be blamed for poor campaign management. It’s the improper usage of modeling and tools that leads to sub-optimal results. So remember, don’t blame the Ferrari for the monkey crashing the car. Ask the right questions of the owner of the monkey.

Well said Siddarth. If you don’t use bid management tools, you have only one option, manual. If you use bid management tools, you have two options, automation AND manual. Knowing when and how to use either tactic lends itself to a higher level of optimization.
I would never turn over my head terms to a bid automation tool.

Hi Siddharth,
I think you make a lot of good points differentiating between the general notion of automated bidding and the more specific scenarios of rules-based bidding and true portfolio-based bidding.
AdWords is a great platform for testing, and so advertisers have the ability to test what works best for them. They can test bid algo’s against human bid optimization and see which seems to work best. In some cases it’s probably an algo, and in others it’s probably a human (even for large accounts with large keyword portfolios). In very few cases, it might be a rules-based bidding system.
