RankBrain allows Google to understand subtle differences in search queries, beyond just keyword matching. It can distinguish queries like "iron cancer" versus "iron and cancer", returning slightly different results. This shows that Google's algorithms are learning from patterns and gaining a deeper understanding of language and context through advances in artificial intelligence. While SEO may become more challenging as Google's abilities improve, it remains to be seen if this leads to search results that are both better and less manipulable over time.

2. Let's explain some things first:
Hummingbird is a name for all of Google's search algorithms
There are many aspects of Google's algorithms and its
updates and each has a cute name:

Spamfighters: Panda, Penguin and Payday

Local results: Pigeon

Penalizing for way too many ads is Top Heavy

Mobile Friendly gives points for pages designed for mobile
devices

Pirate fights copyright infringement etc

3. RankBrain
Is this the beginning of the end?
Google has publicly stated that RankBrain is the third most
important factor in where a page appears in a SERP
BTW there are lots of ranking indicators see 200

4. Google used to ignore syntax, word order, and small insignificant
words like in, on , and etc
But thanks to some impressive advances in
Artificial Intelligence it does not anymore
Let's look at some very subtle differences

5. Two Queries
Iron Cancer & Iron and Cancer
There is no difference in the content of the first 4 results
However, the Google poetry is altered significantly.

6. Two Queries: a closer look
Iron Cancer & Iron and Cancer
But the last four results differ somewhat and the
related searches as well.

7. What does it mean?
Both queries suggest that Iron is implicated in causing or
increasing the risk of Cancer as well as anemia
However, the autocomplete and related searches give the
impression that with Iron Cancer Google considers Iron as
an ELEMENT and compares it with other elements like zinc
that may cause cancer. Whereas, Iron and Cancer
stresses more growth, risk, of iron to cancer and adds
radiation to the mix.
Google is learning

8. Conclusions & Any Questions?
Search Engine Optimization or any attempt to manipulate
Google Ranking can only get harder.
Whether this will mean that Google is a better search engine
and not just spookier remains to be seen.
