SEO courseModule 4 of 10: Your Pages and ContentLesson 4.3
Covering Your Whole Subject: Topic Clusters
How thoroughly your site as a whole covers what your customers need to know: a connected set of pages for each subject, rather than one service page and a handful of random blog posts.
Why it matters
If you only answer someone's first question, another site answers the next five.
Why Google cares
Shows Google what you're the authority on
Do this first
Pick one audience and plan a main page plus five to eight supporting guides.
01What it is
If someone says they’re a football expert but only knows one team’s name, you wouldn’t believe them.
Think of it like
Knowing how to start a car isn't understanding cars. You'd need engines, tyres, servicing, fuel and safety too.
02Why it matters
To the people searching
People want to research the whole journey (valuations, fees, the legal steps, moving) without leaving a site they trust. If you only answer the first question, someone else answers the next five, and they're the ones remembered.
buyers
Want mortgages, surveys, offers and conveyancing explained in one trusted place.
tenants
Want deposits, referencing, rights, moving in and area guides.
sellers
Want preparing to sell, valuation, fees, timeline and the legal steps.
landlords
Want yields, compliance, management, tenant finding and void periods.
To Google and Bing
Shows Google what you're the authority onBroad, connected coverage gives Google more evidence of what your site is about, how the subjects relate, and which page is the authority for each part. Internal links tie it together. Depth doesn't mean hundreds of pages for the sake of it: it means a meaningful network of pages that link to each other.
An agent example
A strong lettings section: the letting service page, a landlord guide, rental valuation, property management, tenant referencing, rent collection, maintenance, end of tenancy, local rental market information, and available rentals, all linking to each other.
03Your turn
Check yours, then fix it
- 1Make a table with four columns: Buyers, Tenants, Sellers, Landlords.
- 2Under each, list every question clients ask you (check your inbox, call notes and viewing feedback).
- 3Next to each question, note: page exists? good or weak? linked from the main page?
- 4Every blank is a gap.
- 1Crawl your site with Screaming Frog, export the Internal list, and sort by folder (/buying/, /renting/, /selling/, /landlords/, /areas/).
- 2Folders with only one or two pages are thin clusters.
I run an estate and lettings agency in [town]. List the 40 questions buyers, tenants, sellers and landlords most often ask, grouped by audience and stage of their journey, so I can check which ones my website answers.
- 1One main page per audience (for example "Letting your property"), plus five to eight supporting guides.
- 2Each guide links to the main page, and the main page links to each guide.
- 3Publish the highest-value topics first.
- 1A Google Sheet is enough: Topic, Audience, Search, Page address, Status, Who, Date.
- 2Let AI help plan the list; write the pages from your own experience.
04Keep it up
Add one or two genuinely useful guides a month, working down your list.
