How To Understand And Optimize AdWords Search Partners Data

Here at Hanapin, we have a monthly training day. We shut down the office and all the account managers spend the morning researching and learning new tricks and techniques, which we teach to each other later in the afternoon. This month, we spent some time diving into the exciting world of Google Search Partners, and I wanted to share some of the insights our team came up with.

What Are Google Search Partners?

When it comes to buying clicks from Google AdWords, the Search Partner network remains one of the least transparent and hardest to optimize areas to work with. The official Google help page for Search Partners is pretty vague about exactly what you get from Search Partner traffic:

“On our search partners, your ads can appear on search results pages, on site directory pages, or on other pages related to the person’s search.”

In layman’s terms, depending on how liberal Google want to be with “other pages related to the person’s search,” you really can’t control anywhere near as much of your search partner traffic as you would like. I had always been under the mistaken assumption that Search Partners referred to search results pages for AOL or and the like — search engines that decided to use Google’s algorithm and in turn get a share of the advertising profits.

However, the scope of the Search Partner network is actually much broader than this. Both internal search results and product pages on sites like eBay, Amazon, Walmart or Target can be part of the network. Let’s take a look at whether Search Partners are right for your AdWords account and then dive into how we might start to identify the sources of your traffic.

Should You Be Using Search Partners?

From analysis across the accounts we manage, there really is nothing inherently wrong with Search Partner traffic. It tends to run at a similar (sometimes slightly higher) cost per conversion to the Google Search Network, and CPCs can be cheaper, too. As a rule, I tend to leave Search Partners turned on when starting a new campaign.

If my account is severely budget restricted from the get-go, I might consider turning them off — but otherwise the additional 20-60% of clicks that Search Partners bring is worth it (at least until you have data to suggest otherwise). If you have a more mature account and you’ve been running with Search Partners long enough to generate statistically significant data, you’ll want to judge the results for yourself. For a quick analysis, you can try using the segment button in your “all campaigns” menu and segmenting by “Network (with search partners).”

How Search Partners look when segmented

To manipulate this data, click segment by “Networks (with Search Partners)” when downloading a campaign report and then use a pivot table¬†that has Campaigns for rows, network for columns, and a custom formula for either CPA or ROAS in your values. Here’s an example I pulled from one of my accounts earlier:

Notice that there really isn’t all that much difference CPA-wise here and that Search Partners are actually performing better in five out of eight campaigns. You might use this data to pause Search Partners anywhere that they are heavily underperforming by going back into your settings and switching to Google Search Network only. The bad news is that despite all of the recent upgrades to bid adjustments, a Search Partner bid adjustment is still nowhere in sight. Also, as a sidebar, don’t worry about your CTR from this traffic dragging down your overall as Google claims it has no impact on your keyword quality scores.

What Are These Weird Queries In My Search Term Report?

Ever seen something in your search term report that looks like this?

Strange Account Keywords

If so, you might have been confused as to why someone could possibly be searching for such a strange term. What’s even weirder is that the term apparently generated 571 impressions. A lone person copying and pasting that into Google might fly with me, but 571 people? Something weird is going on.

These queries are actually the result of Search Partner “searches” — it kind of shook my world to learn this (I’m a little slower than the rest of you who figured this out years ago.) As Google counts product pages on sites like Amazon as Search Partner pages (rather than just regular display), they have to pull a search query from somewhere. In this case, they are pulling the search query from the links that users are clicking to get to that page.

If you want to follow along in your own account here’s how: First, pull a Search Term report and filter for “clicks=0″. Then, sort by impressions and segment by search partners. If you find a query with 0 impressions on the Google Search Network and a ton on the Search Partners Network, you’ve probably found one of these terms. Weird formatting is another giveaway for these. In this case, I’m going to take that search query and type it into Google:

The organic search results should pull up the page your ad was triggered on as that combination of phrase and formatting is normally fairly unique. In this case my search turned up a page on Gumtree:


Notice in the above that Google is pulling the navigation options for “Cars, Vans & Utes” into my search term report? A quick scroll down the page also reveals the placement of the Search Partner ads:


This page seems fairly logical as a Search Partner to me. Someone was clearly searching Gumtree for Nissan vehicles and was shown one of my related ads. Makes sense, right? Well, what about on product results pages (which I find a little more dubious to label as “Search” rather than “Display”)? Here’s a search term from another one of my accounts:


Once again, via the Google search results page, I was able to tie the query to this page where my ad was shown:

An Amazon product page for furniture

Now I don’t know about you, but to me, this really isn’t a search results page — it’s a product page. Yet the ads shown in this page are clearly being counted as Search Partner results (as the user was searching to get here and Google followed them down the rabbit hole):

Search Partner ads on Amazon

I’m not entirely sure how much Display and Search Partner traffic are overlapping in these placements. I know that they work a little differently in AdSense, so my guess is that they are still kept separate.

How Can I Optimize My Search Partner Settings With This Information?

Short answer: with a great deal of effort and patience that might not even be worth it. If you have the time, you could categorically go through your search term report and start spinning queries with lots of impressions out into their own Search Partner ad groups. Take a look at an example I’ve created below:

Search Partner Ad Groups

Through some tireless checking of pages, you can separate out these strange terms by the site they appear on and start to learn more about CPAs by Search Partner. However, I don’t really like the structure of an account organized in this way and the volume of traffic will probably still be too low for the cost of the time you would have to sink into this.

Another hack attempt that I’ve seen before is duplicate campaigns, one with both Google & Search Partners, and one with just Google. By having the Google one set to slightly higher bids, the Google-only campaign tends to win the auction, which leaves just Search Partner traffic for the campaign with both. I don’t really like this method either, as it kind of defeats the point of wanting to optimize search partners on a keyword basis and any CPC changes have to be meticulously recreated for both campaigns. (Accidentally bidding up the Search Partner-only one would break everything.)

For now, we’re left with two real options:

  • Use negative keywords to remove poor performing search partner pages.
  • Turn search partners off entirely if the CPA/ROAS is bad.

Of course in an ideal world, Google would be up front with us about Search Partners. It remains a fevered dream that we will be able to set up Search Partner-only campaigns, segment by specific search partners, and bid adjust for search partners. (It is worth noting that Bing already offers all these things with their partner network, so perhaps we’ll see Google catch up to them eventually.)
