Understanding How Search Systems See Your Website

Author: T.G. Barker | How Google Evaluates Websites | Last reviewed: 11/09/2026.
A website needs more than good content, keywords and backlinks to perform well in search. Beneath the visible pages sits an underlying structure that helps search systems determine which pages are important, how subjects and pages relate to one another, and how authority is distributed across the website.

Just as you would not build a house without a foundation and an architectural plan, a website needs a structure designed around what it is intended to achieve.

At the heart of the process is to build a website Foundation

Build a Stronger Foundation for Search Ranking

That structure should also reflect the priorities of the business. The pages senior management considers strategically important should not be left for search systems to discover by chance; the website itself should reinforce their importance through its organisation, internal relationships and links helping create stronger relationships for those pages to rank for the searches that matter.

By measuring these relationships, we can see whether the website is building a strong foundation for search visibility — or whether the way the site is organised is unintentionally weakening the ranking potential of the pages that matter most.

A website’s structure should reinforce the pages that matter most to the business. By measuring how pages are connected and where authority flows, we can see whether the site has sufficient authority for those pages to rank — or unintentionally directing importance elsewhere.

How Search Systems Learn Which Pages Are Important

Ranking Probability

Every link creates a probability of movement and influence. Graph theory, probability and Markov models give us a practical way to measure these relationships and understand the hidden patterns behind how search systems move through your website and evaluate its pages. From those connections, patterns begin to emerge that can influence the ranking probability of pages across the site.

Measuring the Web Structure That Drives Search and AI

Ranking Mathematics

Graph theory, probability and Markov models provide practical ways to measure the relationships between pages. They help reveal where ranking probability and authority are concentrating across the website — and whether those patterns support the pages the business wants to rank.

Search systems repeatedly discover pages

Structural Interpretation

Search systems do not understand your business priorities in the way you do. They interpret the relationships they encounter between pages, subjects and links. These signals contribute to the structural interpretation of the website — which pages appear central, how subjects are connected, and whether that interpretation reflects what the business actually wants to achieve.

Authority flows through links, context and relationships

Structural Authority Flow

Internal links do more than provide navigation. Their destinations, anchor text and surrounding context help search systems understand the semantic relationships between subjects and pages, user intent, and which pages are intended to answer that intent.

Those same links also influence how strongly important pages are reinforced by the rest of the website. By modelling the probability of movement between pages, we can examine how structural authority flows across the site.

*Search engine crawlers inherently use a variation of this model (like Google’s original PageRank algorithm).

Why website rankings suddenly drop

Ranking Changes

When the model changes, rankings can rise or suddenly drop. When those relationships are weak, confused or change over time, the probability model can change with them. This provides one way of investigating why website rankings suddenly drop even when individual pages appear to have been well optimised.

How the Methodology Works

The Strategic Search Authority Review brings these measurements together to compare the structure search systems actually encounter with the pages and priorities the business considers most important.
