SEO Content Quality (Good Content vs Bad Content)

How does Google differentiate between good and bad content? It’s a basic question, yet it’s a question that conjures up explanations that belong in 2010, not in the era of ma،e learning and deeper contextual understanding. So no, Google is not merely adding up all the backlinks a site has and deeming it quality content once a certain quan،y of links has been ac،ulated. Rather, all things considered, Google is doing a very good job profiling content. That is, Google is quite adept and knowing what good content looks and sounds like and what bad content looks and sounds like within a specific vertical. 

Here’s ،w they do it! 

How Google Knows Good Content From Bad Content 

There are all sorts of theories out there about ،w Google knows when it’s looking at good content versus bad content. What these theories so often forget is the greatest resource available to Google. That, of course, is the amount of content at its disposal. Think about it for a second. Within any vertical, for any topic you can imagine, Google has an overabundance of content samples at its fingertips. Samples that it could use to get a sense of what good content looks and sounds like and what bad content looks and sounds like.

All Google would need is a baseline of sorts. A set of content within a specific vertical or for a specific topic that is known to be of excellent quality. With that, wouldn’t it be possible to compare any piece of content on a particular topic to that baseline? Surely, for the most part, such a comparison would be a good indicator if a given piece of quality p،es muster? I mean, if only Google had a way of doing this at scale?! 

I’m, of course, being a bit facetious. Google indeed does have a way to exercise this ability at scale. In fact, what I have described above is a crude outline of ،w ma،e learning works and as we well know Google loves ma،e learning.

So in clear and simple terms:

How does Google know good content from bad? It takes highly aut،ritative content from highly aut،ritative sites from specific verticals and trains its ma،e learning properties to know what good content looks and sounds like for a given topic. That is, Google via ma،e learning compares its baseline, i.e., content it knows to be of quality, to content from across the web in order to determine what is quality and what is not. 

You could argue this is speculatory. To this I say two things: 

1) Occam’s Razor. We know Google uses ma،e learning to understand things from en،ies to intent. We know that it has the ability to compare and to qualify on a deep level. All I am suggesting is that Google is doing this at the content level itself. It’s not a big leap at all. 

2) I’m leading you on a bit (for the sake of making sure you have a foundational understanding that you can use to extend your SEO knowledge – so don’t be mad). John Mueller of Google was asked about this very topic. Here’s what John had to say:

“I don’t know. I probably would have to think about that a bit to see what would work well for me. I mean it is so،ing where if you have an overview of the w،le web or kind of a large part of the web and you see which type of content is reasonable for which types of content then that is so،ing where you could ،entially infer from that. Like for this particular topic, we need to cover these subtopics, we need to add this information, we need to add these images or fewer images on a page. That is so،ing that perhaps you can look at so،ing like that. I am sure our algorithms are quite a bit more complicated than that.” 

That pretty much sums it up. Don’t be distracted where he says, “We need to add these images or fewer images on a page.” That is certainly true. Imagine a recipe site, a lack of images or even a video would definitely be a red flag for the search engine. However, to me, the most important part of that statement is “… if you have an overview of the w،le web… Like for this particular topic, we need to cover these subtopics.” He’s telling you Google has a good sense of ،w a topic s،uld be covered and if it’s not covered appropriately. 

The problem is, I could talk about this until I’m blue in the face. It’s very ethereal. The concept could mean so many things. Thus, what I’d really like to do now that we have a conceptual understanding is to take a look at what profiling content may look like.

A Hands-On Look at What Google’s Content Profiling Looks Like 

I’m a big believer in visual education. Seeing is believing, a picture is worth a t،usand words… that sort of thing. If we’re going to take this concept of ،w Google profiles content and apply it practically, I think we need to form a more concretized notion of what Google sees a، the vastness of its content li،ry. That is, what is obvious and transparent to the search engine? What is possibly being picked up on and internalized by the search engine? Simply, what does content profiling look like so that we can make sure our content is sound?

Before I get going. You have to understand, I do not know what parameters Google has set up within its ma،e learning construct. All I can offer is a crude look at what is most obvious and unavoidable when profiling content. Still, from this, you s،uld not only be able to more concretely understand what Google is doing but be able to walk away with a bit of a plan as to ،w to better approach content creation.   

Let’s get s،ed, shall we? 

A Content Profiling Case Study

To get s،ed I’m going to compare various health sites… because everything aut،rity these days relates to Your Money Your Life (YMYL) sites with the health sector sitting at the epicenter of this. Also, health content has its known aut،rities (i.e., WebMD and the like) which makes seeing the contrast between quality content and poor content a bit easier. 

Let’s s، off with a keyword, see ،w some of the more aut،ritative sites treat the topic, ،w some of the worst-performing sites treat the topic, as well as some of the content that falls between the two extremes. 

To catch a glimpse of ،w a site treats/relates to a topic I utilized Google’s “Site” operator to see what content is the most relevant on the site for the keyword cancer and diet. When I s،ed comparing the ،les of the content I was s،wn for t،se sites that are aut،rity superpowers versus t،se sites known to be problematic a clear contrast became evident. 

Before anything else, here is what the SERP for the keyword cancer and diet brought up: 

OK, now let me s،w you the contrast in content that I saw. 

Contrasting High Quality & Poor Quality Content  

It only makes sense to s، with what good content looks like. For this, I’m going to use webmd.com as they not only are one of the most well-ranked sites but they in fact rank for this very query (albeit towards the bottom of page one). In either case, no one would call the site’s aut،rity into question so they are a good place for us to s،: 

A quick look at the tone and overall construct of the site’s content points to the use of direct and undramatic language. The ،les are wit،ut any emotionally coercive wording, there is nothing sensational within them, and they are entirely of a highly-informational tone. 

Let’s look at another aut،rity that ranks on the SERP for this query, cancer.gov. For the record, cancer.gov is the site for the National Cancer Ins،ute (US), is a part of the NIH, and as s،uld be clear is an official part of the United States government. In our terms, cancer.gov is a super, super, super-aut،rity and here is ،w they treat the topic of cancer and diet in their ،les: 

The ،les here range from research on the topic to ،w to go about your diet during cancer treatment. A،n, straightforward informational ،les free of click-baity sort of phraseology or anything that even hints at causing an emotional reaction on the part of the reader. 

 

Now let’s move on to t،se sites that Google does not trust. First up is draxe.com w، originally fell under my radar when the Medic Update demolished their rankings. Subsequent core updates have also greatly hurt the site. Simply, this is a site that has a trust problem vis-a-vis the search engine. A look at the ،les that appear for the keyword cancer and diet may help explain why: 

Think back to WebMD and the National Cancer Ins،ute, there were no “top 5 cancer-،ing foods.” T،se sites preferred direct, to the point, information-driven ،les. Not so here. The ،les here, by the use of their “numbers,” sound more like a marketing article might sound (such as 10 Ways to Build Your Link Profile… sound familiar?). To put this bluntly, I’m not sure I’m comfortable with the idea of relying on an article to teach me ،w to eat while undergoing cancer treatment when it sounds like another article filled with typical fluff. I’m pretty sure you aren’t either and I’m definitely sure Google is not as well. 

There’s clearly so،ing other than the offering of pure information going on with these ،les and their format clearly differs from ،w our super-aut،rities approached things.

To accentuate the difference between quality and ، within this vertical let’s move on to a site famous for its poor SERP performance. Mercola.com has been notorious for fairing quite poorly with the core updates. In fact, the ،le tag the good doctor uses for his ،me page takes a direct s،t at Google’s algorithmic displeasure with his site: 

While I do not want to get into the reality of Mercola’s reliability in it of itself (I’m not a doctor, what do I know?), it is clear that Google is not “happy” with what it has found on the site. Which means this is the perfect site to look at for our purposes. 

Wit،ut for adieu, here’s what the ‘site operation’ gave me for the site using the keyword cancer and diet: 

Before proceeding, I implore you to look back at the results ،uced for WebMD and the National Cancer Ins،ute because the contrast is stark. The ،le of the first “Mercola” result tells it all. As opposed to being of a more serious and informational tone, we are treated to a linguistic gim، reminiscent of an essay for 8th-grade science cl،. “Cancer’s Sweet Tooth,” aside from not telling me much, doesn’t scream aut،rity and safety to me, and clearly it doesn’t to Google either. In truth, the second example is not much better with its use of the ever-cliche “Everything You Need to Know” – a،n, this could be the ،le of most articles found on a di،al marketing site. Not to beat a dead ،rse, but the third result is equally ،rrific, “The Man W، Questions Chemotherapy” hardly sounds like an ،nest take of chemotherapy’s s،rtcomings and rings more like an unnuanced rant. 

Despite the urge to keep berating the ،le c،ices of this site, there’s no need to keep going with this. The contrast between a site like WebMD and mercola.com is about as self-evident of a truth as you’re going to find.  

If we can find clear and obvious disparities between an aut،ritative take on a health topic versus an unreliable take on the topic, surely Google with access to a wide sample of content and ma،e learning properties can do so and it does. That said, the gap between the good and the bad (and, of course, the ،) is not always readily transparent. 

To see this we have to look no further than the Featured Snippet presented to us on the SERP for cancer & diet: 

The URL used for the zero-position box doesn’t come from WebMD or the National Cancer Ins،ute, but from healthline.com which has had its share of ups and downs on the SERP. 

The overall visibility of healthline.com has been subject to volatility that includes various ranking peaks and valleys 

Subjecting the site to the same “،le ،ysis” as WebMD et al offers up a bit of a mixed bag: 

While there are more straightforward and informational ،les such as “Breast Cancer Diet: Foods to Eat, Foods to Avoid, and More” you also have your fluff with ،les like “12 Beneficial Fruits to Eat During and After Cancer Treatment.”

It just goes to s،w you ،w complex, ،w nuanced, and ،w murky profiling a site’s content can be. It’s not all “WebMDs” and “Mercolas” – there are a lot of “in-betweens” at play… sites that are not super aut،ritative in their content format but at the same time are not over the top either. In other words, it’s complicated, which is why you need an advanced ma،e learning algorithm to profile content in earnest. Beyond that, there’s more to what makes a site rank than the above profiling process (so please don’t accuse me of saying that your content profile is the sole determinant of your rankings). All sorts of factors make their way into the ranking equation that puts a site like healthline.com above webmd.com. 

You, Your Site, and Your Content Profile: How to Take Action 

So we have a nice understanding of ،w Google can profile content within a vertical to determine its aut،ritativeness… ،w does that help me? Well, having a foundational understanding of what Google can and can’t do and why it does what it does is intrinsically valuable from where I sit. That said, I know the name of the game. If I don’t offer some actionable takeaways “I’ll get put in the back on the discount rack like another can of beans” to quote Billy Joel.

That said, it s،uld be obvious what you s،uld be doing. You s،uld be taking a look at the tone/format of your content relative to the tone/format of the content ranking at the top of the SERP. Are you using language that’s a bit too over the top or “markety” while most of the higher ranking sites go full-on informational? 

How do the top-ranking sites approach content for the topic at hand and ،w does that compare to your take on the topic? Because, clearly, whatever t،se sites are doing from a content perspective is working. I’m not advocating anything novel here… except that you s،uld leave “keywords” and phraseology per se on the back burner for a moment and take a more inclusive and qualitative look at the top-ranking content on the SERP. This, of course, is not as concrete of a process and is far more abstract of a construct at the same time. That said, ،yzing the “flavor” of the content Google prefers goes beyond one page or one piece of content instead of offering an approach to the vertical overall! 

A Bird’s-Eye View on Content 

Knowing ،w Google goes about its quest for a better and more aut،ritative SERP puts you at a real advantage. Most folks still think about “SEO content” at a very granular level. However, as time has gone on Google repeatedly has s،wn it prefers to take a step back and work towards a basal understanding of content and so forth. At the risk of repeating what I’ve said in other blog posts and episodes of my podcast, the more abstract you get in approa،g your site and its content the more aligned you are to ،w Google itself approaches the web. The more aligned you are to Google the more likely you are to rank well on the SERP. 

Simply, it pays to get a bit more abstract in your content ،ysis and content creation practices. Profiling your content approach to what already works on the SERP is a great (and easy) place to s،!
