What Does a Well Structured SEM Campaign Look Like?
Regularly reviewing your account structure and organizing it for relevance is very important for paid search campaigns. Not only will it improve performance but it actually raises the potential of your campaign (more relevant traffic at a lower cost).
Commonly, the structure of campaigns is overlooked as they grow – new keywords and creatives may start to become grouped when they should not be. When this happens, it means users are not presented with the most targeted message for their search (this will affect your click-thrus and conversions) and ultimately lower the quality score determined by the engine. A lower QS will reduce the chance of your ads appearing on the results page while adding an unnecessary premium on the cost-per-click.
So, what is a well organized account structure? That’s not a simple answer, but some general ways to begin setting up campaigns and groups is to categorize keywords based on the following:
• Products (or product type)
• Keyword type (i.e. branded terms, general terms, competitors, etc.)
• Geography
• Your website’s site-map
Other considerations may be budget, potential return, traffic and more, but the list above is a good starting point.
Once you have a general categorization setup, and have written creatives for each of the groups, review your structure with the following three questions in mind. They’ll help you identify if there is a need to modify the groupings and shift keywords and creatives.
1. Are there any generalizations in my creatives that can be more specific? (i.e. “electronics”, “vacation destination”, “software”)
As you answer this question for your creatives and can be more specific on the creative message (i.e. laptops, cameras, mp3 player), it’ll reveal if any of the keywords within the same group will become irrelevant (i.e. when you change a message that says “electronics” to “camera”, then any music player keywords will not work with that creative) – a clear sign that you need to separate out those keywords to another group.
2. Are there groups that have landing pages pointing to a different area of my website? (also phrase the question as “Are there groups that should have landing pages pointing to a different area of my website?”)
More than likely, your website has two types of pages: (a) general pages to describe a concept general area of your business that links to (b) individual separate pages for each of your products or services. If you’re directing users to the general page or if you have landing page in the same group leading to two fundamentally different areas of the site, this is probably another good indication to review that group.
3. Are there any keywords or creatives which have a significantly lower click-thu rate (CTR) or conversion rate from the top keyword and creative performers in the group?
When identifying keywords with significantly lower click-thru rates compared with the group, this could mean that searchers have given you an indication that the creatives being presented for these keywords are not as relevant. Of course, remember to consider statistical significance here and ensure there are enough impressions across all the keywords before considering splitting the group. If there is a clear CTR separation between top performing keywords and the lower performing keywords, then it may be beneficial for a more specific message.
Don’t take this exercise too far and have groups where there is only one keyword. That’s not the point and usually un-necessary as you can use tools like keyword insertion if it comes to that point. Finding a good balance will provide you the flexibility to deliver a very targeted creative message for every keyword in the group, while keeping it simple to manage your campaigns.
I think you’ll find going through that exercise will be revealing. If you do that this regularly, QS should improve and more targeted traffic will come along with a lower CPC.
I want to leave you with one last benefit of having a well organized structure for your SEM campaign. It will also make it simpler to take advantage of Mediaplex’s search remarketing capability that allows you to serve targeted creatives on your display buys based on prior search interactions. More on that in a later post, and you can always contact your account manager to learn about it.
