Mind the Gaps, Maintain Parity: An Introduction to Publisher and Match Type Keyword Parity

By   April 25th, 2012

In a post late last year, we briefly explored the importance of match type parity—expanding broad match keywords to phrase and exact match—to not only improve keyword efficiency, but lower CPCs. Today, we’ll broaden our discussion to review additional strategies for maintaining keyword parity across match types and publishers. This post will help identify where potential keyword gaps reside and provide the necessary tools for filling them.

What’s Great for Google is Good for Bing

As campaigns mature, keywords evolve from experiments to proven revenue drivers. These proven revenue drivers often perform similarly across publishers. If a newly added Google keyword achieved 100 clicks with a 5% conversion rate at a 200% ROI over the last two weeks, it makes sense to test the same keyword on Bing. Unfortunately, many advertisers fail to maintain keyword parity across publishers, even when the failure to do so can result in missed revenue opportunities.

Identifying where these keyword gaps reside can prove to be a daunting task. To promote engine parity, implement tracking when engaging in keyword expansion. (Third-party solutions, like Marin Software, can help track and report on these changes at scale.) Take detailed notes on where, when and why these keywords were added to the account. These notes are not only essential to analyzing performance, but are critical when copying top performing keywords across publishers. To retroactively assess parity, download a sorted keyword performance report and apply an Excel vlookup to compare publisher keyword sets. Take note of where the gaps are for top performing keywords.

Bring the Whole Family

Copying exact and phrase match keywords to broad match type is a simple strategy for reaching a larger audience and discovering additional keyword opportunities. However, an increase in traffic doesn’t always correspond to an increase in performance. When introducing broad match keywords, be relentless in your efforts to find appropriate negative keywords.

Driving improvements in keyword efficiency often requires the use of phrase and exact match keywords. Expanding broad match keywords to phrase and exact allows for effective segmentation of keyword traffic and performance metrics. A keyword on broad match only captures the traffic for its phrase and exact match counterparts. Consequently, the clicks and conversions are aggregated to a single keyword. With the same keyword on broad, phrase and exact match, clicks and conversions can be segmented based on match type and precise optimization strategies can be implemented for each keyword.

But Remember to Silo

Consider the following dilemma. A keyword running on Google across all three match types has a broad match bid that exceeds the phrase and exact match bids. As a result, the broad match keyword cannibalizes traffic that should otherwise be captured by the phrase or exact match keywords. To effectively expand keywords from broad to phrase to exact match types, and segment performance based on match type, you must implement match type silos.

Match Type Silos

 

 

 

 

 

 

 

 

 

Match type silos not only promote match type parity but, with appropriate negative keywords, guarantee proper query-to-keyword matching. (For more on match type silos, read our whitepaper on managing negative keywords.)

Be mindful of publisher and match type gaps. Once these keyword gaps have been filled, remember to optimize. Researching negative keywords, setting appropriate keyword bids and generating relevant ad creative are just a few tasks to keep in mind. Implement these strategies and share your results with us.
