The Search Initiative Rad Paluszak: Cracking The Code 4 Machine Learning Machine learning is a method of data analysis that automates analytical model building. It is a branch of artificial intelligence based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention.

The Search Initiative Rad Paluszak: Cracking The Code 5 Deep Learning Deep learning is part of a broader family of machine learning methods based on learning data representations (e.g. ontology), as opposed to task- specific algorithms. A deep neural network (DNN) is an artificial neural network (ANN) with multiple layers between the input and output layers. The DNN finds the correct mathematical manipulation to turn the input into the output, whether it be a linear relationship or a non-linear relationship. The network moves through the layers calculating the probability of each output.

The Search Initiative Rad Paluszak: Cracking The Code 15 RankBrain RankBrain is an algorithm learning artificial intelligence system, the use of which was confirmed by Google on 26 October 2015. It helps Google to process search results and provide more relevant search results for users. M a c h i n e L e a r n i n g F r o m T h e S E O P e r s p e c t i v e If RankBrain sees a word or phrase it isn’t familiar with, the machine can make a guess as to what words or phrases might have a similar meaning and filter the result accordingly, making it more effective at handling never-before-seen search queries or keywords.

The Search Initiative Rad Paluszak: Cracking The Code 26 TF-IDF, WDF*IDF, WTF Mathematically, TF-IDF is the product of how often a keyword appears on a page (TF) and how often it is expected to appear on an average web page, based on a larger set of documents (IDF). WDF*IDF (Within Document Frequency*Inverse Document Frequency) - an analysis method to determine keywords and terms that sustainably increase the relevance of published texts. The result is the relative term frequency and weighting of a document, relative to all other web documents including analysed keyword.

Chaos Theory • Branch of mathematics that deals with systems that appear to be orderly but, in fact, harbor chaotic behaviors. • Chaos theory applies to complex, dynamic systems highly sensitive to initial conditions. • The deterministic nature of these systems does not make them predictable. • Chaos paradoxically leads to formal structure and order. 1,653 Launches 9,800 live traffic experiments 18,015 side- by-side experiments 130,336 Search quality tests

The Search Initiative Rad Paluszak: Cracking The Code 37 Ontology A model for describing the world that consists of a set of types, properties, and relationship types.

The Search Initiative Rad Paluszak: Cracking The Code KNOWLEDGE BOMB “RankBrain uses all sorts of ontologies (multidimensional vector spaces) to learn the Web. = Google MUST understand your site structure.”

Flat, dead, WTF? Not Good ☺ . 0 1 Visible clusters, some core pages hard to crawl. Looks OK, but… . 0 2 All (trust me) core pages within 1 click from … EVERYWHERE. Great structure.

The Search Initiative Rad Paluszak: Cracking The Code (OBVIOUS) KNOWLEDGE BOMB “The easiest way to show Google your site’s ontological nature is to use silo-based structure. DO NOT SPAM IN THE URLs!!!!”

The Search Initiative Rad Paluszak: Cracking The Code KNOWLEDGE BOMBS 1. “Ontological Content Structure is just as important as the site structure.” 2. “Content Cannibalisation is usually more dangerous than keyword cannibalisation.”

The Search Initiative Rad Paluszak: Cracking The Code Ranking in post “Medic” world. S U P E R - T E C H N I C A L G O O D I E S 1. Build Personas that are not easy to track down. Why the f*ck would you call it Jimmy Hendrix? 2. Ensure good, tree-like navigation. Menu (drop-downs, mega-menu, etc.) is your friend. 3. E-A-T is not just author bio and social media. Google also needs to “confirm” whatever you’re saying in external sources! 4. Do not write fluff content. Google understands the context, intent, etc. 5. Don’t stuff ads and affiliate links in every possible whole. Medic and following updates are strictly focused on quality measures. 6. Plan for latent intent. Cover your back whenever possible. 7. Avoid content cannibalisation. No need to have the same sh*t in every article. 8. Get rid of unnecessary pages. I’ve recently ranked more sites removing than creating content. 9. Look at your index management. Housekeeping is always a good thing! 10. Save crawl budget. Google ain’t gonna waste it on yo stinky site!
