Most SEO beginners have heard of backlinks - links from someone else's website. Backlinks to your site will (in general) help boost your position in the search engine results pages (SERPs). Your pages need authority to rank, but getting links from other websites takes time and effort; in many cases, getting backlinks can cost money.

What if you could give authority to your pages without needing to deal with backlinks from other sites? It turns out, you can (sort of). Here's how...

Usually people talk about backlinks from one site to another site. There are also internal links. Links from one site to somewhere else on that same site. Internal links have a similar effect for SEO as do external backlinks. If a there is a page that you link to from many pages on your own site, then that page will tend to rank higher in the search engine results pages (SERPs).

Internal links do not create authority the same way that backlinks from external sites do. Rather, internal links distribute the authority that has already been passed to your site from those backlinks. Good internal link structure is important because internal links allow you to focus your site's authority into ranking important pages rather than wasting it on junk.

Another piece of information that most SEO beginners are aware of is that some links are stronger than other links. On a technical level, this is because backlinks get their power from other backlinks. If a webpage has zero links pointed at it (0 backlinks) and that webpage then creates a backlink to your site, that backlink will be weak. In contrast, if a webpage has many links pointed at it (many backlinks), backlinks from that webpage to your site will be much stronger.

For example, in the example below (pulled from Wikimedia Commons) a backlink from site E would be much more powerful than a backlink from site K.

Note: While the general concept remains unchanged, note that this image was originally created to demonstrate PageRank, which is no longer publically updated.

This is why, for example, homepage links are almost always very strong. It's doubtful that Google's algorithms explicitly/specifically state that links from a site's homepage should be powerful. Instead, it is noticing two things:

  • External Backlinks. The more obvious of the two reasons. The most common page for others to link to is to the homepage, so of course this page will be quite powerful given that fact.
  • Internal Linking. The more interesting and commonly overlooked reason. In most cases, every page on your website will have a link back to your homepage. This means that any time that a backlink is built from another website to any page on your site--any page at all--your homepage is only one step away. This means that your homepage is going to get tons of power from no matter how your backlinks are distributed.

Homepage links aren't automatically powerful; they're powerful because the standard way of structuring websites makes them powerful under Google's algorithms.

How Can Internal Linking be Used to Improve Your Rankings?

Similarly to how links in the body of articles posted on other websites send authority to the pages they link to, when links are made from the body of internal pages to other internal pages, that power is then directed to those internal pages. An easy strategy to take advantage of this fact is to:

  1. Find posts on your website that are of lesser importance, such as pages that have low search volume or a poor conversion rate.
  2. Find posts on your website that are of higher importance, such as pages that have good search volume and/or good conversion rates. Ideally, these should be pages that you can realistically expect to rank on the first page, such as pages that are currently hovering around the second or third page
  3. In the text of the pages of lesser importance, add links to the pages of greater importance. This helps focus your link equity into pages that will be able to take advantage of that power.

Top level pages, such as those linked to in a site's main navigation bar, tend to rank highly. A large part of this is because these pages have internal links to them from each and every page on the website. Any link to any page on a website will indirectly boost pages that are only one tier away more than that same link will boost pages that require multiple tiers of navigation. This means that the pages that you choose to include in your internal navigation menus will receive a lot of authority.

One easy way to structure this is to have two main navigation menus. The first menu being a header menu that links to the pages that users need to access the most (FAQ/about, contact, order, etc) and the second being a sidebar or footer that links to:

  • The top level/parent pages for each of the main product pages and/or blog post categories (scroll down to the section on silo structure for more information)
  • Any particularly important pages, for example a "featured posts" section on your sidebar linking to blog posts that target particularly important or valuable keywords

Internal links don't create authority or power; rather, they distribute the power and authority that external backlinks have brought into your website. Cramming an excessive number of links into a a page on your website will not generate more power; it will take the same amount of total power and distribute it across your a larger number of pages (meaning that each individual page gets less power). In general, it's better to rank a smaller number of pages at the top of the SERPs (top 10, ideally #1) than it is to rank many pages on page #2 and beyond.

Obligatory cliche but accurate advice.

What are Silos? How to Organize Your Content into Categories (Using Silo Structure)

Example Silo

Take a look at the example below, which shows what a silo structure for product pages / landing pages on a large sports equipment website might look like:

  • Home
    • Buy Baseball Equipment
      • Buy Baseball Bats
        • Buy Aluminium Baseball Bats
        • Buy Wooden Baseball Bats
        • Buy Tee-ball Bats
      • Buy Baseball Mitts
        • Buy Leather Baseball Mitts
        • Buy Youth Baseball Mits
        • Buy Metal Baseball Mits
    • Buy Football Equipment
      • Etc
    • Add 5,000 more pages here

A diagram showing what silo structure may look at is below:

Directories Within Silos

Silos are groups of related pages on a website that are structured to interlink between them. Each page in a given silo links to other pages within that same silo. In particular, all pages within a silo should (generally) contain a directory that links to some combination of the following pages:

  • The silo's parent page
  • The other sibling pages in the same silo
  • The direct children of the page (if your silo has many levels)

In the example above, if you're on the "Buy Aluminium Baseball Bats" page, there should be a menu/sidebar/footer/whatever that has links to the parent category "Buy Baseball Bats" and to the sibling pages "Buy wooden baseball bats" and "Buy tee-ball bats."

Interlinking Between Silos From the Main Text of Your Pages

In addition to a directory, when using a silo structure, it is ideal to set up your internal linking so that there is occasional interlinking to other pages in the silo within the body of the main text of the landing page. For example, again referencing the example silo above, "These aluminium bats are great for bashing in the skulls of the undead. If you prefer a fresh oak scent while you ride out the the end of human civilization, you might check out some aluminium options.

The goal here being that you set up your pages so that links to particular categories will allow authority/"link juice" to flow to the other pages within the same silo. This allows you to get a lot more bang for your buck with backlinks to large sites (not to mention it's also good for user experience and conversion rate).

The Sitewide Sidebar, Footer, and/or Other Navigation Menus - Link to the Parent Pages of Each Silo. For inner pages on a domain to receive authority, they must be connected to the rest of the site. It is important to design your site so that all pages (or at least all of the pages you care about ranking) are hooked up to the "power grid" so that they can benefit from the authority passed to your site from external backlinks. Because linking to every single page from the sidebar is impractical for any site larger than twenty pages or so, the standard way to do this is to link to the parent pages of each category from a sidebar, footer, or other navigation menu. This allows for the authority from any link pointed at any given page to flow to each of those parent pages, which each contain their own directories of links to their children to which authority is then funneled.

Why Should You Create a Silo?

To Rank Large Sites. The main difference in terms of ranking large sites is that you're looking more at building silos (categories and subcategories) and then targeting pages as groups, generally with a focus on the parent pages in those categories and a smaller number of links to inner pages within those silos.

For an example like the sports site shown previously, you're going to generally point tons of links at the home page, lots of links at "Buy Baseball Equipment" and "Buy Football Equipment," a good amount of links at "Buy Baseball Bats and "Buy Baseball Mitts" and some/intermittent/occasional links at "Buy Aluminium Baseball Bats," "Buy Wooden Baseball Bats," and the like.

To Raise a Site's Overall Authority and Power. When new pages are added to a website that has effective siloing, those pages will:

  • Rank highly in the SERPs with minimal external backlinks because they're able to take advantage of the site's overall authority.
  • Be crawled and indexed quickly because:
  • Their logical directory structure makes them easy to locate and crawl
    • Their inherent authority means that Google actually wants to crawl and index these pages

These two factors are a large part of why well-known authority sites tend to have new pages indexed quickly and why pages on authority sites tend to rank well even without explicit offpage linkbuilding being done.


Effective use of internal linking an extremely powerful and consistently underestimated aspect of ranking a website in the SERPs. In fact, it is one of many ways that onpage optimization gets overlooked despite the extreme power of onpage optimization. If you like making money from search engine optimization, improve your internal linking and onpage optimization.

Is there any kind of limit to building internal links? For example if I build too many internal links will it hurt SERP positions? If you can share your insight on this it would help me with updating my site's SEO.

There's no cap, necessarily. Although there is a finite amount of authority to pass around your site. The general concept behind internal linking is to indicate which pages are the most important; if every page is important, then none of them are important.

Sir, I can do you a nice SEO.

It is good enough to keep 2 or 3 internal links to a post. It will not any any drastic differnce, if you build more intrenal links on s single post.

So, it is good to have 2-3 internal links per post or article.
