What Is Main Content?
Google now defines main content as any part of a page that directly helps it achieve its purpose.
Think about walking into a hardware store for a door hinge. The parking lot, the greeter and the aisle signs all help, but you came for the hinge. If you walk out without it, nothing else about the visit counts. The hinge is the main content.
For a roofer, the page about metal roof replacement has one job: help a homeowner decide whether metal is right for their house and who should put it on. The photos of finished metal roofs, the explanation of what it costs and why, the cost calculator, and the reviews from people who had it done are the main content. The menu, the footer and the sidebar are the parking lot.
Google Has Been Grading Main Content for Years
The idea of main content has been in Google's search quality rater guidelines for about a decade. Raters are real people Google pays to look at search results and judge whether the right pages came up. Google's own comparison is a good one: raters work like the feedback cards a restaurant hands its diners. Their scores don't change where any page ranks, but they show Google whether its results are working.
What changed this week is that Google moved the definition out of the rater handbook and into the guide it tells business owners to read. Marie Haynes, who has studied Google's algorithms since 2008, points out that these guidelines describe what Google trains its machine learning ranking systems to recognize. The raters teach by example, and the system learns to spot the pattern on its own. So the four things raters look for are a very good picture of what the rankings reward.
Raters Judge Main Content on Four Things
Effort is how much human work went into the page. Google's examples of high effort include writing original analysis. Pages generated automatically from feeds, or piles of AI text with nobody overseeing them, count as little to no effort. Giving credit to other sources doesn't count as effort either.
People notice effort even when they couldn't tell you what they're noticing. For example, you can spot the difference between a custom-built set of kitchen cabinets, and the ones that came out of a flat-pack at a big box store. They both do the same job, but you can easily see the difference of effort involved.
Originality is information or perspective a reader can't already get somewhere else. If five roofers hand you the same brochure, then you can't judge if one is better than the other on that information alone. Other than price, you need something else to rank them on. The roofer who explains why the north side of a roof here in the Rogue Valley grows moss first, and what that means for when to replace it, is saying something the other four didn't.
Talent or skill is whether the page shows the ability to give the visitor a good experience: clear writing, video that's well produced, tools that work. Google notes that not every page needs an expert. Someone sharing a new way they found to clear snow off their driveway doesn't need credentials.
Accuracy means the facts are right. For topics that can seriously affect someone's health, money or safety, Google says the content must be highly accurate and match expert consensus.
How Does Google Know if Readers Like Your Page?
Every decision to buy anything is an emotional one. We decide with how we feel, and then we use logic to explain it to ourselves afterwards. Think about the last time you hired someone to work on your house. You probably had a couple of quotes that were close on price, and you went with the one you felt better about.
Google can't read your feelings, but it can see what you do about them. If you click on a page, read for three seconds and hit the back button, you've told Google you didn't like what you found. If you stay, read the whole page and call the business, you've told it the opposite.
That's also why Google doesn't really care whether a person or AI wrote your page. It cares whether people like it, and people don't like mass-produced content. It bores them, and bored people leave.
So a fast, technically perfect website gets you invited to the dance, but it doesn't make you royalty. The main content does that.
Google Wants to Know Who Wrote It, How and Why
The update also asks you to look at your pages the way a stranger would, and ask who wrote this, how it was made, and why it exists.
If someone you've never met hands you advice about your roof, the first thing you want to know is who they are. A web page is the same. Put a real name on it, and link that name to a page that tells people who you are. Google now says outright that making up authors, with fake names, AI headshots or credentials nobody earned, is deception. So make sure you're not using fake testimonials.
How the page was made only matters when a reader would wonder about it. If AI wrote a big part of your page, Google suggests saying so, and saying how it helped.
Why the page exists is the question Google cares about most. Think about two salespeople. One listens to what you need and helps you figure out what to buy. The other just keeps talking about the same features and hopes it's what you want to hear. You know which one you'd buy from. A page written to help the person reading it is the first salesperson. A page written mainly to pull in search traffic is the second, and Google can tell the difference. Pumping those pages out with automation also breaks Google's spam rules.
What to Do With Your Own Website
Start with the pages that matter most to your business and ask one question about each: what's on this page that only we could have written? For the roofer, that's his photos, his jobs, his local knowledge, and his name. If the honest answer is nothing, that page is the place to start.
Put the answer where the reader lands. Marie's practical advice is to put the main answer or tool front and center, so nobody has to scroll past an introduction to find it. She also expects Google's next big ranking update to come soon. Pages built around real main content are the ones that tend to come out ahead.
