How to Plan a Silo Structure

Key Takeaways

• Plan a silo by starting with the services that earn you revenue, then building topics around each one.
• Each silo needs one parent page, usually 5 to 15 supporting pages, and a short list of links that connect them.
• Map every page on paper or in a spreadsheet, with its keyword, search intent and link targets, before you write anything.
• Keep URLs, navigation and breadcrumbs consistent so Google and AI assistants can see which topic a page belongs to.
• A planning pass for a small business typically takes one to three weeks, and results usually need a few months to show.

Start With Revenue Pages, Not Keyword Lists

The best silo plan starts with the services or products you most want to sell, not with a spreadsheet of keywords. Keywords describe what people type, but your revenue pages decide which topics deserve a full silo.

List every service you offer and rank them by profit per job and by how much capacity you have. A roofing company may earn more from full replacements than from small repairs. That ranking tells you which silo to build first.

Then ask what a buyer needs to know before they call. Each answer is a candidate supporting page. If you want a refresher on the concept itself, our explainer on what content silos are in SEO covers the basics.

Seven Planning Steps Before You Write a Page

You can plan a silo in seven steps: choose the topic, gather questions, group them, assign search intent, set the hierarchy, design the links and document everything. Do them in this order, because each step feeds the next.

1. Choose one core topic per silo

A silo covers one service or one tightly related group of services. “Water heater services” is a silo. “Plumbing and HVAC and remodeling” is three silos. If you cannot describe the topic in a short phrase, it is too broad.

2. Gather every question and sub-topic

Pull ideas from your own sales calls, estimate requests, Google Business Profile questions, “People also ask” boxes and autocomplete suggestions. Your customer-facing staff often know the real questions better than any tool. Write them all down without filtering yet.

3. Group ideas into clusters

Sort the list into groups that a single page could answer well. If two questions need the same answer, they belong on one page. If one question needs a long, multi-part answer, it may need its own page or even a small sub-group.

4. Assign search intent to each page

Label every idea as informational, comparison, cost, local or ready-to-buy. Check the current search results to see what Google already shows for each query. If the top results are all service pages, a blog post is unlikely to rank there.

5. Set the hierarchy

Place one parent page at the top, then group supporting pages beneath it. Most small-business silos work with two levels. Add a third level only when a sub-topic has at least three or four pages of its own.

6. Design the internal links

Decide which pages link up to the parent, which link sideways to siblings and where the few cross-silo links go. Do this before writing so the copy can include natural link sentences. The details are in our guide to internal linking for silo SEO.

7. Document the plan

Put the whole map into one spreadsheet. Anyone who writes, edits or publishes should be able to open it and know what comes next. A plan that lives only in your head will drift within a month.

A Worked Example: A Home-Service Silo Map

Here is how a plan might look for a hypothetical plumbing company in Greenville, SC planning a water heater silo. This is an illustration of the method, not a real client result.

Page role	Example topic	Intent	Links to
Parent	Water heater installation and repair in Greenville	Ready to buy	All supporting pages
Supporting	Tankless vs tank water heater	Comparison	Parent, cost page
Supporting	Water heater replacement cost	Cost research	Parent, tankless comparison
Supporting	Signs your water heater is failing	Informational	Parent, repair page
Supporting	Water heater flushing and maintenance	Informational	Parent, failure signs
Supporting	Same-day water heater repair	Urgent, local	Parent, cost page
Supporting	Water heater permits and code basics	Informational	Parent

Notice that every supporting page links to the parent, and only the closest relatives link to each other. That keeps the structure clear and avoids a tangle of links.

How Many Pages Does a Silo Need?

Most local-business silos work well with one parent page and roughly 5 to 15 supporting pages. The right number depends on how many distinct questions buyers ask and how much competitors cover.

Use these rules of thumb as ranges, not guarantees:

• Small service with few variations: 4 to 6 supporting pages.
• Core service with many options and price points: 8 to 15 supporting pages.
• Multi-location service: one parent per service, plus a location page for each area you truly serve.

Check your competitors. Search your main keyword and note how many topics the best-ranking sites cover. You do not need to match their page count, but you should cover the same essential questions.

Quality matters more than count. Five useful pages that answer real questions beat fifteen thin ones. Thin pages dilute the silo and create the kind of problems described in our article on common silo architecture mistakes.

Plan Your URLs, Navigation and Breadcrumbs

Your URLs, menus and breadcrumbs should all show the same hierarchy as your silo map. When all three agree, search engines and AI tools can read the topic structure without guessing.

URL structure

Use a folder for each silo, with the parent at the folder root and supporting pages beneath it. For example, a water heater silo could use /water-heaters/ for the parent and /water-heaters/tankless-vs-tank/ for a child. Keep slugs short, readable and free of dates.

Decide on your URL pattern before publishing. Changing URLs later means redirects, and redirect chains can slow down how quickly Google settles on the new structure.

Navigation

Put your parent pages in the main menu and let supporting pages appear in dropdowns or on the parent page itself. Avoid linking every supporting page from every other page through a huge footer or sidebar. That flattens the structure you are trying to build.

Breadcrumbs

Add breadcrumbs that mirror the folder path, such as Home, Water Heaters, Tankless vs Tank. They give visitors a quick way back up and add another clear signal of where each page sits.

Write Down Your Internal Link Rules First

A written set of link rules keeps every writer and editor consistent. Decide the rules once, then apply them to every new page.

A simple rule set looks like this:

• Every supporting page links to its parent at least once, using descriptive anchor text.
• The parent page links to every supporting page in the silo.
• Supporting pages link to siblings only when the topics genuinely overlap.
• Cross-silo links are allowed when a reader would truly need that other topic, and they are kept few.
• Anchor text describes the destination and is not repeated word for word everywhere.

For a deeper look at how these links work in practice, see our guide to building a content silo structure. It picks up where planning ends and the build begins.

Use AI Tools Carefully During Planning

AI tools can speed up topic research and outline drafts, but they should not decide your structure. You know your customers, your service area and your margins; a language model does not.

Good uses include clustering a long list of questions, suggesting related sub-topics you missed and drafting outlines for you to edit. Poor uses include accepting a generated page list without checking search results or letting a tool invent facts about your services. Our article on using AI for SEO content creation explains where it helps and where a human review is essential.

Planning Mistakes That Waste Months

Most planning failures come from skipping a step, not from a lack of effort. These are the ones we see most often when we review small-business sites.

• Building the silo around keywords alone. A topic with search volume but no link to a service you sell will not bring in leads.
• Overlapping pages. Two pages targeting the same question compete with each other. Merge them or give each a distinct intent.
• Starting too many silos at once. Finish one before you begin the next, or none will be strong enough to rank.
• Ignoring existing pages. Audit what you already have first. Often you can fold old posts into the new structure instead of writing from scratch.
• Forgetting local relevance. Service area names, local codes, climate and common property types belong in the plan, not as an afterthought.
• Leaving out a measurement plan. If you do not choose your success metrics now, you will not know whether the silo worked.

Audit Existing Content Before You Map New Pages

Before adding pages, sort every existing page into keep, merge, rewrite or remove. This often saves weeks of writing and avoids duplicate topics.

Export your URLs and note each page’s topic, traffic from Google Search Console and whether it brings calls or form fills. Then decide where each page fits:

• Keep: the page matches a silo topic and performs reasonably.
• Merge: two or more pages answer nearly the same question.
• Rewrite: the topic is right but the content is outdated or thin.
• Remove or redirect: the page has no place in any silo and no value to visitors.

When you merge or remove pages, set up 301 redirects to the closest relevant page so visitors and link value are not lost.

Pre-Launch Planning Checklist

Use this checklist before you write the first new page. If you can tick every item, your plan is ready to build.

1. Each silo has one clear core topic tied to a service you sell.
2. Every planned page has a primary keyword, a search intent and a purpose.
3. No two pages target the same question.
4. The parent page is mapped to every supporting page, and the reverse links are listed.
5. URL folders, menu items and breadcrumbs match the hierarchy.
6. Existing pages are sorted into keep, merge, rewrite or remove.
7. Each page has an owner and a due date.
8. You have chosen the metrics you will review, such as impressions, rankings for parent keywords, calls and form submissions.

Realistic Timelines and Costs for Planning

For a small business, planning one silo usually takes about one to three weeks of part-time work. A full site with several silos can take four to eight weeks, depending on how much content already exists.

Those ranges shift with a few factors: how many services you offer, how messy your current site is and how quickly you can answer questions about your business. Waiting on approvals is the most common cause of delay.

Costs depend on who does the work. If you plan in-house, the cost is mostly your time and perhaps a keyword research subscription. If you hire an agency or freelancer, planning is often quoted as a one-time project, and prices vary widely with scope. Ask for a deliverable list so you know what you receive, such as the page map, keyword assignments and link rules.

After launch, expect to wait several weeks for Google to crawl and index new pages and a few months before you see ranking movement. Competitive markets take longer. Treat early data as direction, not a verdict.

Plan for Maintenance From Day One

A silo is not finished when the last page publishes. Build a light maintenance routine into the plan so the structure stays clean as you add content.

Review each silo every quarter. Check for pages that have stopped getting impressions, questions you have not yet answered and new services that need their own silo. When you add a page, update the parent and the relevant siblings in the same session.

Keep your spreadsheet current. It should always show the live structure, not the structure you intended six months ago.

Frequently Asked Questions

How many silos should a small business plan?

Most small businesses should plan one silo per core service, which usually means two to five. Start with the service that earns the most profit, finish it, then move to the next. Trying to build every silo at once spreads your effort too thin.

Do I need a separate silo for each city I serve?

No, you do not need a full silo for each city. A single parent page per service, plus a strong location page for each area where you truly work, is usually enough. Add city-specific supporting content only when real local details, such as codes or common property types, make it useful.

Should my blog posts be part of a silo?

Yes, blog posts that answer questions about a service belong in that service’s silo. Link them to the parent page and to related siblings. Posts that do not relate to any service, such as company news, can sit outside the silos.

Can I plan a silo on an existing website without rebuilding it?

Yes, you can usually reorganize an existing site in stages. Audit your pages, assign each to a silo, adjust internal links and menus, and only change URLs where the benefit outweighs the redirect work. Many sites improve with link and content changes alone.

What tools do I need to plan a silo?

A spreadsheet, Google Search Console and a keyword research tool are enough for most small sites. Add a crawler such as Screaming Frog when you need to audit a larger site. The quality of your thinking matters more than the tool list.

How do I know if my silo plan is working?

Look for steady growth in impressions and rankings for the parent page’s keywords, followed by more calls and form submissions from those pages. Check Google Search Console monthly, but judge results over a few months, not a few days. If supporting pages rank while the parent does not, review your internal links and page intent.

What is the biggest planning mistake to avoid?

The biggest mistake is creating overlapping pages that compete for the same query. It splits ranking signals and confuses both visitors and search engines. Give each page one clear question to answer, and merge any that overlap.
