Site structure: how page hierarchy helps search

Every website has a structure, whether anyone planned it or not. On many membership sites it grew by accident: a blog with hundreds of posts in one long date-ordered list, a menu that says Blog, Courses, Community and About, and a pile of guides that link to nothing in particular. Visitors can't tell what the site covers, and neither can search engines.

Site structure is how your pages are organized into a hierarchy: broad sections at the top, narrower topics beneath them and individual pages at the bottom. A clear hierarchy helps search engines understand which pages matter most and how topics relate, and it helps people find their way from a single article to everything else you offer. It is one of the few SEO improvements that also makes your site noticeably easier to use.

What a good hierarchy looks like

Think of your site as a tree:

• The home page at the top, linking to your main sections.
• Section pages for each major subject, such as Plumbing or Floors, each introducing the subject and linking to its topics.
• Topic pages within each section, such as Taps and Sinks, gathering related articles.
• Individual articles at the bottom, each linking back up to its topic and section.

Three or four levels are enough for most membership sites. The aim is that any important page can be reached in a few clicks from the home page. Pages buried many clicks deep look less important to search engines, and fewer visitors ever find them.

A good hierarchy works like the outline of a long document. The advice in writing headings that help readers and search engines applies to your site as a whole: each level should make sense on its own and lead logically to the one below.

Section and topic pages do the heavy lifting

The pages in the middle of the tree matter most. A section page shouldn't be a bare list of links. It should:

1. Explain the subject in a few paragraphs, in the words people search for.
2. Point beginners to the best place to start.
3. Link to every topic or article within it, grouped sensibly.
4. Link to any course, members-only resource or teaser page on the same subject.

These hub pages often rank for broad searches that no single article could win, and they pass visitors and search engines down to the detailed pages beneath. If your platform generates category pages automatically, the same principles apply; see category and tag pages: helpful or harmful for SEO?

Breadcrumbs: showing where a page sits

Breadcrumbs are the small trail of links near the top of a page that shows its place in the hierarchy, such as: Home > Guides > Plumbing > Fixing a dripping tap. They help in three ways:

• Visitors arriving from search can see where they are and move up a level with one click.
• Search engines get a clear signal of how pages relate. With breadcrumb structured data, a labeled version of the trail in the page's code, search engines may show the trail in results instead of a bare web address.
• Every page gains links to its parent pages automatically, strengthening your hubs.

Most membership software and themes can display breadcrumbs. Make sure they reflect your real hierarchy rather than a date archive or a technical folder name.

A worked example: a home repair membership

Emeka runs a membership teaching homeowners to handle their own repairs. His public site had three hundred articles in one blog list, a menu with four items and no way to browse by subject. His most useful guides were five or six clicks from the home page, reachable only by paging through the blog.

He sketches a new tree on paper:

• Sections: Plumbing, Walls and Ceilings, Floors, Doors and Windows, Outdoors, Tools.
• Topics under Plumbing: Taps and Sinks, Toilets, Pipes and Leaks, Drains.
• Articles under Taps and Sinks: fixing a dripping tap, replacing a tap cartridge, unblocking a sink and so on.

Each section gets a hub page with an introduction, a “start here” guide and links to its topics. Each topic page lists its articles in a sensible order, from simplest to hardest. Breadcrumbs appear on every article, and the main menu now lists the six sections. Any article is now within three clicks of the home page. Emeka keeps every article's existing address, so no links break, and simply adds the new hub pages and breadcrumbs around them.

Common structure problems

• Flat lists by date. A blog sorted only by date hides older, often better, content.
• Too many sections. Twenty top-level categories are as confusing as none. Keep top-level sections few and broad.
• Orphan pages that nothing links to, which search engines may rarely find.
• Two structures in parallel. A public site organized one way and a members' library organized another confuses people who move between them. Where possible, mirror the same sections in both.
• Restructuring without redirects. If a reorganization changes addresses, redirect every old one to its new home.

Your site structure plan

1. List your public pages and group them into five to eight broad sections.
2. Within each section, group pages into a handful of topics.
3. Write a hub page for each section, with an introduction, a starting point and links to every topic.
4. Add breadcrumbs to every article, based on this hierarchy.
5. Update your main menu to show your sections.
6. Check that every important page is within three or four clicks of the home page.
7. Keep existing addresses where you can, and redirect any that must change.
