Trump has accused Google of rigging search results against him - but here's what actually happens when you search for Trump news on Google

We started with the phrase "Trump news," since this is the one Trump cited in his Tweet. The majority of the results are from publications with a more left-leaning audience.

We used data collected by both the Columbia Journalism Review and Pew Research Center that ranked media outlets on where their audience falls on the political spectrum. These rankings don't necessarily mean a publication is "liberal" or "conservative," only that their readers identify in one of those groups.

Note that it wasn't always possible to label a publication based on its audience's political ideology. And we also took note of how many opinion stories popped up in the results.

Left-leaning audience (blue): 21

Right-leaning audience (red): 3

Moderate/No clear party affiliation (green): 5

Opinion articles (circled): 3

While Google Search seems to present news stories from sources favored by more liberal-leaning audiences, there could be plenty of good reasons for that.

In a handful of quick searches, there were zero instances where articles from conservative news sources appeared more often than articles from publications with left-leaning or moderate audiences. But there could be a few key reasons why Google Search showed me stories from sources with more left-leaning audiences.

One reason could be that those are the sources I read on my own time. While I don't often check CNN and it appeared often in my results, I do read stories from The New York Times, Washington Post, and — obviously — Business Insider. I use Google Chrome as my main browser, and it's possible that's the reason those news sources appeared more often for me.

Another reason could be that there just aren't that many center-right publications. According to CJR's analysis, publications like ABC News, Politico, and CNN fall just to the left of center in terms of their readership. But there are very few similar center-right sites. Here's how CJR puts it:

"There are very few center-right sites: sites that draw many Trump followers, but also a substantial number of Clinton followers. Between the moderately conservative Wall Street Journal, which draws Clinton and Trump supporters in equal shares, and the starkly partisan sites that draw Trump supporters by ratios of 4:1 or more, there are only a handful of sites."

Because Google says it's committed to "high-quality content" in response to search queries, it likely steers clear of far-left and far-right media outlets in its results to avoid biased news stories.

In other words, it's possible that Google's search results for Trump news are less biased precisely because of the type of publications that appear in its results.
