Agriculture buyers search for reliability, durability, and correct specifications. Google looks for content that explains products clearly, supports farming decisions, and guides users toward the items that fit their operations. When your agricultural SEO content provides real-world practicality and links related categories together, Google treats your website as a specialised resource rather than a generic supplier.
Internal link graph analysis is one of the most powerful — yet most overlooked — forms of SEO research. Most businesses and even many SEO practitioners in London focus on content, keywords, or backlinks, but they forget that Google’s ranking decisions begin with how a website structures its own internal authority. When you map a site using PageRank and graph theory, you can see which pages Google perceives as the “real” centre of the website, regardless of what you intend to rank. When Google updates search, it’s often changing how these systems integrate. Because they’re interconnected, even a small tweak can produce large changes across the results. This exposes hidden problems, authority leaks, and structural weaknesses that would never be visible from a normal audit, and it reveals exactly how Google reads your entire domain from the inside out.
With this insight, you can deliberately shape authority flow, reinforce your core topics, and gain ranking power without writing a single new piece of content.
Very few SEO consultants know how to conduct this type of analysis because it requires a mix of technical disciplines: graph theory, probability modelling (Markov chains), and data-driven interpretation of link structures. These skills go far beyond standard SEO tools or checklists. Most SEOs rely on surface-level audits—meta tags, speed checks, basic on-page optimisation—because those tasks don’t require this deeper analytical capability. As a result, they often miss the real reasons why certain pages fail to rank, or why Google misunderstands a site’s purpose. By contrast, using PageRank modelling and internal graph simulations gives you a high-level view of how Google’s crawlers interpret the site structurally, which is critical for modern SEO. This level of insight should be a part of every serious SEO practitioner’s toolkit, yet it remains one of the rarest and most valuable techniques in the industry.
Our research involved creating a map of what this website for farming supplies showed us. Using our inlinks for analysis, we built a graph model of this website — every URL became a node and every link between pages became a directed edge.
We then ran PageRank (Google’s original link-weighting algorithm) to see which pages the internal linking structure secretly boosts the most.
The wrong pages had the most authority.
The top PageRank page was /country-clothing-and-footwear, meaning Google sees the site as mainly about clothing, not farming supplies.
System pages were also too strong, such as basket/signin/wishlist — these were absorbing authority because they appear in the navigation or template.
Farming-related categories were not central in the internal graph and received very little authority.
The homepage was unexpectedly weak, meaning it wasn’t distributing PageRank properly.
No Farming Hub existed, so Google had no single page representing your main topic (“Farming Suppliers”).
Top 30 PageRank Graph
Showed the strongest pages and how they interlink. This revealed a heavy bias toward clothing and equestrian pages.
Top-6 PageRank Graph
Highlighted the six strongest pages, making it obvious that non-farming pages dominated.
Fixed Simulation Graph
We added a new /farming-suppliers/ hub page and redistributed links.
After this, farming pages became the dominant nodes — exactly what you want for SEO.
What the Clean Top-6 PageRank Graph Reveals
The graph shows the six most authoritative pages on the site, based purely on internal link flow (PageRank). Each node is labelled with the URL slug, instead of the full URL, so you can see structure more clearly:
horse-wear
electric-fencing-solar-panels
studs
home
wormers-and-endoparasites
country-clothing-and-footwear
These are the pages Google’s internal link graph considers “important.”
Now here’s what it actually shows:
The two strongest nodes (largest circles) are:
This signals that:
your theme
your navigation
and/or your category linking
is pushing Google to believe the site is mainly about:
This is a major mismatch if your commercial focus is Farming Suppliers, Agricultural Supplies, and equipment.
The long, heavy arrows flowing into country-clothing-and-footwear mean:
this page is linked from nearly everywhere
often from top-level navigation
sometimes from repeated blocks (header, footer, sidebar)
This makes it the PageRank magnet of the site.
This page drains internal authority that should flow to:
horse supplies
poultry supplies
electric fencing
farm equipment
feed or fencing categories
and your soon-to-be hub page /farming-suppliers/
Pages like:
receive fewer links and almost no high-authority inbound connections.
In graph terms:
They don’t function as “central” nodes.
Their PageRank contribution is secondary.
Google sees them as low-value or less core to the site’s topic.
These pages cannot rank well until they become part of a stronger, internally linked cluster.
Normally the homepage dominates a PageRank graph.
Here, home is small relative to other nodes.
This tells us:
navigation → homepage links may be weak
deeper categories may have more internal references
homepage content might not link outward effectively
your theme might be heavily weighted toward category links instead of homepage contextual links
This reduces the homepage’s ability to distribute authority like it’s supposed to.
The graph confirms that the site lacks a “topic anchor” for farming or agricultural intent.
There is:
no farming-suppliers hub
no farm-equipment hub
no livestock-supplies hub
no agricultural-supplies cluster
Because of this, PageRank splinters into random category nodes instead of supporting a coherent SEO topic.
Google can’t figure out:
So it falls back to the strongest nodes — which happen to be equestrian clothing categories.
The circular arrows on nodes (self-loops) represent:
breadcrumb links that repeat the page
menu structures linking to the same URL
auto-generated “related pages” blocks
image links pointing to themselves
possible duplication from pagination or canonical loops
Self-loops don’t help SEO, but they distort the internal graph by artificially inflating PageRank.
The clean graph shows that:
To fix this, you need to:
Create a Farming Suppliers hub page
Link major categories → farming hub
Add homepage → farming hub links
Link categories to each other (cluster model)
Reduce template links to clothing and non-farming pages
Add cross-links in blogs pointing to farming hub + key categories
Add nofollow to system pages (signin, basket, wishlist)
Doing this will reshape the entire internal link graph and give you ranking momentum.
We generated two important tables.
Listed:
each URL
its PageRank
its percentage of total authority
This table revealed:
0.52% → clothing page (wrong)
0.30% → horse-wear, fencing, etc.
0.30% → homepage
farming categories blended in with non-farming ones
This showed sitewide misalignment of authority.
With the Farming Hub in place, the numbers transformed:
This table proved that:
Here’s what we implemented in the simulation (and what you’ll implement on the site):
URL:
/farming-suppliers/
Purpose:
hold the majority of PageRank
cluster all farming categories
target your primary keyword directly
act as the topical authority center
Anchor examples:
“Farming suppliers”
“Farm supplies”
“Agricultural supplies”
This channels authority into the right place.
Especially:
poultry supplies
electric fencing
horse supplies (if farming-related)
stable equipment
feed
supplements
farm equipment
tools
This creates the hub-and-spoke structure Google prefers.
Clothing should:
NOT be in the primary nav
NOT be a top-level category
NOT receive sitewide authority
This prevents misranking.
basket
signin
wishlist
These should NOT be absorbing PageRank.
Add:
farming-suppliers link
top categories
farming-related contextual sections
This raises the site hierarchy.
Implementing all fixes gives you:
Google now sees you as a Farming Supplier, not a clothing store.
Category pages jump from 0.3% to 9% PageRank.
Your new hub page becomes the strongest page on the site.
Fixes internal chaos from the previous random structure.
Rankings, crawl behavior, and search placement will move significantly within weeks.
Internal link graph analysis is one of the most powerful ways to understand how Google sees a website. It reveals which pages receive the most authority, where the structure is weak, and what Google thinks the site is really about. Most SEO consultants never do this because it requires technical skills in data analysis and graph modelling, not just basic audits. That means they often miss the real reasons pages fail to rank. By using PageRank simulations and link-flow mapping, you can quickly identify hidden problems and reshape authority so your most important pages rise in search results.
