YMYL Pages are …
• News and Current Events
• Civics, Government, and Law
• Finance
• Shopping & Ecommerce
• Health and Safety
• Groups of People
• OTHER!

@schachin
Takeaways.
But Google says it does not know what YMYL site
is in search, so how does it target them?
YMYL Sites

@schachin
Takeaways.
The devil is in the details.
• They ARE NOT looking at YMYL SITES
• They ARE LOOKING at YMYL QUERIES (Entities)
YMYL Sites

@schachin
Takeaways.
Entities
(fancy word for NOUN)
YMYL is addressed at the QUERY LEVEL

@schachin
What are CORE UPDATES?

@schachin
The HINT is in the NAME: “CORE”

@schachin
Core Updates = Core Ranking Factors
Google is tweaking the
CORE RANKING FACTORS
to better surface the type of sites
as described in the Quality Raters Guide.
It is a QUALITY UPDATE.

@schachin
• Accuracy of Content
• Authorship
• Credentials of Authors
• Bios (unless a news site)
• Linking Out
• Links to Certifications
• Known Brands
• Reviews
What Medic or the CORE UPDATES are NOT.

@schachin
• Swear words in your comments
• Tone of your content
• Schema (while good not related to CUs)
What Else?
And ALSO are NOT.

@schachin
Takeaways.
This is what CORE UPDATES
are about -- per Google.

@schachin
Core Updates ARE SEVERE (Generally).

@schachin

@schachin
Check the site for issues related
to Core Ranking Factors - then fix!
FIX a CORE UPDATE?

@schachin
USUALLY - THE ISSUES WILL BE GLARING!
The issues also might have been on the site for YEARS
With NO NEGATIVE EFFECT!
FIX a CORE UPDATE?

@schachin
Core Updates are boringly simple.
Yet complex.

@schachin
Takeaways.
Simple but Complex.
Query Issues
• Relevance
• User Intent
• Shifting
Overall Site Quality
• Technical
• Usability
• Content Quality
• Inbound Links (likely not)

@schachin
First 
Make sure to CHECK YOUR QUERIES FIRST
Core Updates happen at the QUERY LEVEL
see where you lost IMPRESSIONS & CLICKS in Google Search Console
Don’t Use Third Party Tools.

@schachin
Next run a site crawl and find your technical issues 
Make sure to fix TECHNICAL ISSUES FIRST*
because if Google cannot crawl and index your pages properly,
the REST DOES NOT MATTER.
*This includes internal linking, site architecture, & page speed.

@schachin
Next run a site crawl and find your technical issues 
Make sure to fix TECHNICAL ISSUES FIRST*
Most important.
• Site Architecture
• Internal Linking
• In the past page speed, but with CWV may be
removed now, still make sure you fix it for PE.

@schachin
Takeaways.
Then Check & Improve 
Next  How to Fix Core Updates.
• Query Relevance & Content Quality
• Check Google Search Console for Query Drops
• Many sites drop on just a few CORE terms
• Are you pages RELEVANT to the entity searched
• Is your content meeting USER INTENT?

@schachin
Takeaways.
Important Note on Time to Recover!
• Originally you could not recover at all until the next update.
• NOW according to John Mueller, if they tweak ranking factors in
between major updates you may see SOME improvement.
• Still would not expect to see a full recovery without a new rollout.

Google Helpful Content Update
“Our classifier for this update runs continuously, allowing it to monitor newly-launched sites and
existing ones. As it determines that the unhelpful content has not returned in the long-term, the
classification will no longer apply.
This classifier process is entirely automated, using a machine-learning model.”

@schachin
https://ai.google/static/documents/exploring-6-myths.pdf

@schachin
Main Points
• Ranking signal NOT an update
• First known ranking signal that has machine learning
• Continually rolling but with delays, so can take 2-3
months to catch-up with your site
• Sitewide but severity based on the number of issued
pages
• Other factors can lessen the devaluation (like
content quality on other pages)
• Seems to target what Panda and Penguin did with an
additional focus on the quality of “usefulness” or
“helpfulness”
• Is your content differentiating itself?

Myth: can’t detect AI content.
AI systems can predict that content is likely
created by AI.
How?
AI cannot create anything. It is only able to
use what is knows to detect patterns and then
in the case of content, use those patterns to
“write content”
So, AI can recognize patterns of how AI would
“write” and determine a likelihood that this
item is written by AI.
It is not 100%, but it can be done.
Google has an algorithm that detects AI
repurposed scraped content.

Moving from NLU into early NLP

@schachin
Google
https://searchengineland.com/how-google-uses-artificial-intelligence-in-google-search-379746
BERT. ”BERT, Bidirectional Encoder Representations from Transformers, came in 2019, it is a neural
network-based technique for natural language processing pre-training. looking at the sequence of words
on a page, so even seemingly unimportant words in your queries are counted for in the result.”
• Year Launched: 2019
• Used For Ranking: No
• Looks at the query and content language
• All languages
• Language Training Model: Prescoring
• Very commonly used for many queries
• Can you optimize for it? No

@schachin
Google
BERT. Example.
“if you search for “can you get medicine for someone at my pharmacy,”
BERT helps us understand that you’re trying to determine if you can pick up medicine for someone else
at your pharmacy.
Before BERT Google ignored the FOR, AT, & YOUR and would mostly surface results about how to fill a
prescription
For offers context.

@schachin
https://bensen.ai/elmo-meet-bert-recent-advances-in-natural-language-embeddings/
BERT, or Bidirectional Encoder Representations from Transformers, improves upon
standard Transformers by removing the unidirectionality constraint by using a masked language
model (MLM) pre-training objective. The masked language model randomly masks some of the tokens
from the input, and the objective is to predict the original vocabulary id of the masked word based only
on its context. Unlike left-to-right language model pre-training, the MLM objective enables the
representation to fuse the left and the right context, which allows us to pre-train a deep bidirectional
Transformer. In addition to the masked language model, BERT uses a next sentence prediction task
that jointly pre-trains text-pair representations.
There are two steps in BERT: pre-training and fine-tuning. During pre-training, the model is trained on
unlabeled data over different pre-training tasks. For fine-tuning, the BERT model is first initialized with
the pre-trained parameters, and all of the parameters are fine-tuned using labeled data from the
downstream tasks. Each downstream task has separate fine-tuned models, even though they are
initialized with the same pre-trained parameters.
Sesame Street and Search: BERT Definition

@schachin
LLMs can go forward and backwards
to predict an unknown (masked) term and/or sentence.
Also uses root words, so play for player/playing/played are the same
This allows them to derive context for what is being written.
Previous models were based on word vectors (entities and knowledge graphs)
LLM Transformers are Bidirectional
https://blog.google/products/search/search-language-understanding-bert/

@schachin
Sesame Street and Search: Why is BERT Special?
BERT can disambiguate words from the sentence and apply meaning forward and backward to those
words in order to predict a masked word using those applied contexts. This is SUPER EFFICIENT!

@schachin
Because BERT can go forward and backwards
to predict an unknown (masked) term and/or sentence.
Also uses root words, so play for player/playing/played are the same
Sesame Street and Search: Why is BERT Special?
https://blog.google/products/search/search-language-understanding-bert/

@schachin
Why are LLMs So Special?
Large Language modeling can determine the meaning of words in context
so it can better predict the next word in the sentence.
These sentences mean two different things forward and backward.

@schachin
How does this work? Transformers
What are transformers?
A transformer in language processing is a type of computer program
that is designed to understand and generate text.
It does this by using a special type of algorithm called self-attention.
Self-attention allows the program to look at all the words in a
sentence or a piece of text at once, and understand how they relate
to each other, rather than just one word at a time like traditional
methods. This way it can better understand the meaning of the text,
and can generate text that is more similar to how a human would
write.

@schachin
Confused yet?

@schachin
Simply put BERT or language modeling is
“Language modeling – although it sounds formidable –
is essentially just predicting words in a blank.”

@schachin
Why does it matter to us as SEOs?
It mostly doesn’t.
It was a breakthrough in Language Model
Processing, because it is …
+ VERY Fast
+ Uses fewer resources
+ Provides better understanding of content

RankBrain. Google told us RankBrain helps Google understand how words are related to concepts and
can take a broad query and better define how that query relates to real-world concepts.
• Used For Ranking: Yes (post ad hoc)
• Works for all languages
• Applied post scoring ad hoc
• ”Kitchen Sink” result
• Can you optimize for it? No

@schachin
Rank Brain is used for Unknown Queries where entity
meanings/relationships are unclear or unknown.

• Can be combined with other algorithms such as neural matching
• No way to optimize for it
• BUT you can help prevent your page from getting one of these

@schachin
Simple answer to a very complex issue?
Do your normal query research,
check the SERPs for Rank Brain issues
and then just write naturally.
Using specificity (topical hubs) PLUS
depth & breadth to create holistic content.

@schachin
Write holistic content? Does your content have depth, breadth, & semantic relationships?
Use terms that are semantically related. Image search is great for showing related terms.

@schachin
Schema.

@schachin
Do You Schema?

@schachin
What is Structured Data?
https://developers.google.com/search/docs/guides/intro-structured-data

@schachin
What is Structured Data?
Structured data for SEO purposes is on-page markup that
enables search engines to better understand the information
currently on your site’s web pages, and then use this information
to improve search results listing by better matching user intent.

@schachin
Why Does Schema Matter?

@schachin
We can act as the interpreter and help “teach”
Google what our site is about.

@schachin
Adding semantic mark-up
(structured data via schema) allows us to tell
Google what WE SAY our site is about and WHAT
RELATIONSHIPS we define within it.

@schachin
We can act as the interpreter and help “teach”
Google the context of our content.

@schachin
We can help give Google a clearer understanding.
That helps us help Google better answer
the questions users ask
and to better surface our content for those users
We give our data meaning
Google Understands

https://ai.google/research/pubs/pub47323
“Understanding natural language queries is fundamental to many practical NLP
systems. Often, such systems comprise of a brittle processing pipeline, that is not
robust to "word salad" text ubiquitously issued by users. However, if a query
resembles a grammatical and well-formed question, such a pipeline is able to
perform more accurate interpretation, thus reducing downstream compounding
errors.”

@schachin
Google is an Answer Engine.
PARTIALLY BECAUSE
…that is how MACHINE LEARNING works best.

@schachin
THINK in Intent, Query Terms, & Context.

@schachin
And Questions!

@schachin
Takeaways.
• Think Search Queries NOT Simple Keywords
• Write in natural language
• Write using holistic content
• Focus on depth and breadth with related terms
• Add Structured Data
• Use well formed text (i.e. questions) when you can.
Takeaways.

@schachin
What About E-E-A-T?

@schachin
E-A-T.
EEAT IS Conceptual?
E-E-A-T has no
• Definition given by Google
• No ranking factors directly tied to it
• So, you are at best guessing what it means
• Why Guessing?
• Because it comes from the Quality Raters Guide which was
NEVER meant to be an SEO GUIDE.

@schachin
E-A-T Exception.
EEAT IS Conceptual with ONE Exception?
E-E-A-T = The E of Experience
Google does NOT care who your expert is, BUT if you have reviews, they
want reviews to have a personal component, so…
• Use ”I” first person terms
• Use video and images your company recorded and shot
• No stock!
• Have the person write about their personal experience with the
product
