Mastering Google AdWords Marketing Negative Keywords
By: Richard Ball

If you are managing a Google AdWords marketing campaign it is critical to employ negative keywords. This is particularly true if any of the keyword phrases in the ad campaign are broad or phrasematched. Negative keywords cause an ad to not be shown if any of the keywords are in the search phrase. This is important for a few reasons. First because the ad will not be shown for keyword phrases that are not relevant there will be fewer clickthroughs that do not convert to sales. Second the overall CTR (clickthrough rate) will be higher because there will be fewer instances of searchers viewing the ad but not clicking. The higher CTR will cause the ad to attain a higher position without requiring a higher CPC (cost per click). This will save you money and increase the ROI of your Google AdWords marketing campaign.

Lets look at an example. Suppose an online store sells organic food. The stores Google AdWords campaign has an ad group with these broadmatched keywords:

organic food

organic food store

Using at least one keyword research tool (and preferably more) will reveal many keyword phrases that are searched on that contain the phrase organic food but are clearly not related to purchasing organic food for people to eat (as opposed to pets). For example using the Overture (Yahoo) search term suggestion tool yields these results for the keyword phrase organic food:

24904 organic food

1286 organic dog food

1243 organic food store

1020 organic baby food

689 organic pet food

685 organic food online

465 organic cat food

373 benefit of organic food

It would likely not benefit the online store thats selling organic food for people to eat to display an ad next to search results for the keyword phrase organic dog food. Adding dog to the AdWords ad group will prevent the ad from appearing for that particular search phrase. Keep in mind that the Overture search term suggestion tool usually does not differentiate between singular and plural forms of keywords. From this list heres how to set up negative keywords for the Google ad campaign:

dog

dogs

baby

babies

pet

pets

cat

cats

benefit

benefits

Only place one negative keyword per line. Precede each keyword with a dash. The preceding indicates to the Google AdWords system that the

keyword to follow is a negative keyword. If any of the negative keywords are in a search phrase the ad will not appear next to the search results.

If the online store sells organic baby food it is still worth including baby and babies for this general organic food ad group example. A separate ad group could be created for items as specific as organic baby food. Each ad group should have a very tight focus. Do include both the singular and plural forms of negative keywords as people often search using both. For example buy organic baby food or buy organic food for babies are both searches that would cause an ad to be shown for a Google AdWords ad group containing organic food as a broadmatched keyword phrase.

The list of negative keywords for an ad group should evolve. Start with a list derived from a handful of keyword tools but add to the list over time. The web logs for your web server are an ideal source for discovering new negative keywords. Whether you sift through the raw web logs or have a web statistics program to access the log data be sure to examine the searches yielding hits from your ad group. For example if you see a search in the logs for organic food gives me gas then add gas as a negative keyword. Often there are hundreds of unique searches that people perform that do not show up in any keyword research tool. Gradually build up your list of negative keywords to avoid receiving traffic that will not convert to sales.
