A site can publish a page for every service and dozens of related articles yet still leave those pages poorly connected. Silo SEO groups related pages by topic and uses internal links to show how those pages fit together.
Modern silo SEO no longer requires sections of a site to be isolated from one another. The hierarchy can stay intact while pages in different topic groups link to one another when their subjects genuinely overlap.
Silo SEO organizes website content around distinct services, subjects or business areas.
An HVAC company, for example, might organize its site around AC repair, heating, heat pumps and maintenance. Each main service might have its own page, supported by articles answering narrower questions about that service. An article about an air conditioner blowing warm air might link to the AC repair page. A heat pump vs. furnace guide could link to both heat pump and heating services.
Google says links help it discover pages and understand their relevance. It recommends that every important page receive a link from at least one other page on the site.
There are two core approaches: physical and virtual silos, plus a hybrid model that combines both.
A physical silo uses the site’s URL structure to show hierarchy. A plumbing company might use:
For a new site, that folder structure can mirror the planned hierarchy from the start.
That said, URL folders alone do not create a strong SEO hierarchy. Google says it generally relies on links between pages to understand site structure and may use internal links as a signal of relative page importance.
An established site generally does not need a URL migration simply to produce tidier silo folders. Google advises site owners to expect temporary ranking fluctuations during significant URL changes.
A virtual silo creates topical relationships mainly through internal links. URLs can remain relatively flat:
An HVAC hub can link to these services, while supporting articles link to the most relevant service pages. For an established site, the advantage is that existing URLs can stay in place while internal links establish the topic hierarchy.
A hybrid silo uses both URL hierarchy and internal linking to organize related pages. For example, a plumber might keep service pages under /services/ while blog posts use /blog/, then connect both through a plumbing hub and contextual links.
For an existing local-business site, a hybrid model can avoid the disruption of rebuilding the URL structure while still improving internal organization.
Traditional silo SEO often discouraged links between different silos. That creates neat diagrams but can make a site less useful.
A personal injury firm may have separate car accident and insurance claim clusters, but an article about an insurer undervaluing an accident claim is relevant to both. Blocking the link purely to preserve the silo boundary would serve the structure rather than the reader. Ahrefs similarly argues that relevant cross-silo links should not be prohibited.
A modern topic cluster usually includes:
For local business sites, topic clusters preserve the hierarchy without forcing genuinely related pages apart.
Links from major service pages give crawlers a route to deeper, more specific pages. They also reduce the risk of important pages becoming orphaned with no incoming internal links.
Someone researching cosmetic dentistry might start with a broad overview, then look for veneers, whitening, pricing or financing. Those links let the visitor move from the overview to relevant service, pricing or financing pages without starting another search.
Internal links signal the relationship between service pages, FAQs and educational content. A roofing article about hail damage, for example, can reinforce the relevance of the company’s storm damage and roof repair pages.
Not every page has equal business value. A dentist may want its “Dental Implants” page to be more prominent than an old blog post. A service linked from the main navigation, a relevant hub and related articles naturally receives more internal prominence than an old post buried several clicks deep.
Organizing pages by topic makes missing coverage easier to see. If a roofing company has a roof repair hub but nothing on storm damage, emergency repairs, leak diagnosis or repair vs. replacement, the missing subjects stand out immediately.
List your important service pages, location pages, articles, FAQs and other indexable content. Group them by topic and look for:
Do this before creating more content. Many local businesses need better organization more than they need more blog posts.
Start with the services the business actually sells and the questions its customers actually ask. A law firm might use its practice areas, while a home-services company could separate HVAC, plumbing and electrical work. Do not create categories simply because a keyword tool shows search volume.
Decide which existing or planned page should satisfy each distinct search intent. For example:
Assigning one primary page to each intent also limits overlap between pages competing for the same query.
A hub should explain the main service or subject, then route readers to its major subtopics. Do not turn it into a page filled with links and little useful content. Give the hub enough substance to stand on its own, then link readers to the specific services or questions they are likely to need next.
A strong internal linking system should:
Use descriptive anchor text. “Learn about our emergency plumbing services” is more useful than “click here.”
Do not bury the services that matter most to the business several levels deep in the site. Google can use the number of links required to reach a page as one indication of its relative importance.
A typical local business site can usually expose its main services without adding several layers of menus and submenus. Use the main menu for primary services and hubs, breadcrumbs or contextual links for deeper pages.
Local businesses create pages like:
The problem comes when the same template is repeated with little more than the city name changed. A worthwhile location page might show which services are available there, examples of nearby work, area-specific questions, service boundaries or practical directions. Create a city page only when there is something genuinely specific to say about serving that location.
In Search Console, watch impressions, clicks and queries for the cluster as a whole. Separately track whether its key service pages are indexed, internally linked and generating conversions.
Also watch for multiple URLs appearing for the same search intent. If several URLs keep appearing for the same intent, decide whether they should be merged or rewritten to serve different purposes.
Google says there are no additional technical requirements for appearing as a supporting link in AI Overviews or AI Mode. Pages still need to be crawlable, text-accessible and reachable through internal links.
A local business site does not need a separate “AI SEO” architecture. Its service and supporting pages simply need to cover the subject and link to one another coherently.
Do not treat a silo boundary as a rule against linking to another relevant topic. If a service page, location page or article is relevant to another section of the site, link to it. A dental insurance article may belong in a financing cluster but still warrant a link to the treatment page it discusses.
A tidy folder path is an organizational choice, not evidence that Google sees the pages as a coherent topic group. The pages still need substantive content and links that connect them to the rest of the topic.
For example, placing three plumbing pages under /plumbing/ does little if those pages are thin, disconnected and difficult to reach. A plumbing hub linking directly to drain cleaning, water heater repair and emergency plumbing pages gives those URLs an actual relationship.
Do not add extra levels of hierarchy simply to make the site look organized. Primary service and location pages should sit only a few navigational steps from the homepage or a relevant hub.
For example, a dentist should not force its dental implant page into a path like /services/restorative/advanced/tooth-replacement/implants/ if patients can reach it more easily through a simple “Dental Implants” link from the main services section.
Internal links should describe what the destination page offers, but they do not need to use the same exact-match keyword every time. Fit the anchor text to the sentence instead of repeating one exact-match phrase across the site.
For example, every link does not need to say “emergency plumber Dallas.” A natural phrase like “our emergency plumbing service” can describe the destination just as clearly.
A local business does not need multiple articles or service pages that answer essentially the same search intent. Google specifically warns against creating content for every possible search variation when the purpose is to manipulate rankings.
If several pages answer the same query with essentially the same information, merge them rather than maintaining separate keyword variants. For example, separate pages for “AC repair cost,” “air conditioner repair price,” and “how much does AC repair cost?” may overlap heavily. Those three queries are close enough in intent to be handled on one AC-repair-cost page.
Do not change working URLs simply to fit a new folder structure. Change an established URL only when there is a concrete reason beyond making the folder structure look tidier.
For example, if a well-performing page already lives at /water-heater-repair/, moving it to /plumbing/water-heaters/repair/ purely for a tidier silo is usually unnecessary. Leave the URL alone and link the page from the plumbing hub and other relevant plumbing pages instead.
If your site has accumulated service, location and blog pages without a coherent internal structure, TechGlobe IT Solutions can audit how those pages are grouped and linked and identify where the architecture needs to change. Talk to us about restructuring your site.
In simple terms, a silo groups pages about the same service or subject and links them so their relationship is obvious. On a local business site, each major service typically becomes a topic group with related FAQs, guides or location content around it.
Yes, but not in the old sense of sealing each silo off from the rest of the site. Topic grouping still works but arbitrary restrictions on relevant cross-links do not.
Physical silos use URL structure to show hierarchy. Virtual silos create those relationships mainly through internal links.
Yes. If a page genuinely belongs in the reader’s path through another topic, link to it even if it sits in a different silo.
There is no fixed number. Build them around your main services and customer needs rather than trying to reach a specific count.
