Google and Broad Match
February 11, 2021
I read “Google Is Moving on From Broad Match Modifier.” The essay’s angle is search engine optimization; that is, spoofing Google’s now diluted relevance methods. The write up says:
Google says it has been getting better at learning the intent behind a query, and is therefore more confident it can correctly map advertisements to queries. As that ability improves, the differences between Phrase Match and Broad Match Modified diminishes. Moving forward, there will be three match types, each with specific benefits:
- Exact match: for precision
- Broad match: for reach
- Phrase match: in Google’s words, to combine the best of both.
Let’s assume that these are the reasons. Exact match delivers precision. Broad match casts a wide net. No thumbtypers wants a null set. Obviously there is zero information in a null set in the mind of the GenXers and Millennials, right? The phrase match is supposed to combine precision and recall. Oh, my goodness, precision and recall. What happened to cause the Google to reach into the deep history of STAIRS III and RECON for this notion.
Google hasn’t and won’t.
The missing factor in the write up’s analysis is answering the question, “When will each of the three approaches be used, under what conditions, and what happens if the bus drives to the wrong city?” (This bus analogy is my happy way of expressing the idea that Google search results often have little to do with either the words in the user’s query or the “intent” of the user (allegedly determined by Google’s knowledge of each user and the magic of more than 100 “factors” for determining what to present).
The key is the word “reach.” Changes to Google’s methods are, from my point of view, are designed to accomplish one thing: Burn through ad inventory.
By killing off functioning Boolean, deprecating search operators, ignoring meaningful time indexing, and tossing disambiguation into the wind blowing a Google volleyball into Shoreline traffic — the company’s core search methods have been shaped to produce money.
SEO experts don’t like this viewpoint. Google doesn’t care as long as the money keeps flowing. With Google investing less in infrastructure and facing significant pressure from government investigators and outfits like Amazon and Facebook, re-explaining search boils down to showing content which transports ads.
Where’s that leave the SEO experts? Answer: Ad sales reps for the Google. Traffic comes to advertisers. But the big bucks are the big advertisers’ campaigns which expose a message to as many eyeballs as possible. That’s why “broad reach” is the fox in the relevance hen house.
