Content Expansion

Trying to get your pages to rank on search engines for as many different phrases relevant to the corpus it’s in is key to growing your organic traffic.

When looking to grow your traffic online many people think Content Expansion is just adding more articles to your website.

Although adding more articles is expanding your reach for keywords to be ranking then you will be surprised by how many more phrases your existing content could start to rank for by expanding on the page level gap analysis.

The new Information Gain SEO Google Patent is a clear statement to all SEOs to provide additional value to your content, your competition is not talking about.

Types of Content Expansion

There are several ways in which you can expand the content reach on your website:

  • Domain Level Gap Analysis – Checking what pages your domain is missing
  • Page Level Gap Analysis – Checking what headings your page is missing
  • Heading Level Gap Analysis – Checking what phrases your header section is missing

Let’s dive deeper into each of these content expansion methods.

Domain Level Gap Analysis

When looking to become an expert in a topic you need to make sure you are covering all the articles needed on the subject matter.

Cover the whole topic in its entirety at a domain level (create all pages relevant to the top-level topic)

If you are not covering the whole topic in its entirety you are simply not ambitious enough to dominate your niche.

Creating a content plan roadmap as part of your research is crucial because this is where you will map out the pages to meet the search intent.

Keyword research using ahrefs or semrush is the easy part but then mapping out what pages these keywords go onto is where the fun begins.

The keyword clustering to match the SERP results is probably one of the most important factors in a site winning or losing in the SERPs.

The key here is to try and cover every single article on your website from information posts, pillar posts to transactional pages.

Domain level gap analysis can also be beneficial for reaching your target audience and keeping them on the page, as the topic they are already looking for might result to further queries, which they will then be able to find on your site.

Page Level Gap Analysis

When looking to become an expert in a singular subtopic you need to make sure you are covering all the information needed on the subtopic query.

Cover the whole topic in its entirety at a page level (is your article the best / most informative out there)

If you are not covering the whole subtopic in its entirety you are simply not ambitious enough to dominate for the given search query.

Looking to thoroughly analyse and research the subtopic on your page is what will get you #1 rankings.

Progressive Optimisation at a page level is one of the easiest ways to grow your site’s traffic.

Some other sites that are ranking for the same target market and the same content topic might have some headings that you haven’t included- page level gap analysis will be beneficial to view these competitors and help you to be producing content that will attract your target audience the most.

Heading Level Gap Analysis

When looking to become an expert in a very specific section of a topic you need to make sure you are covering all the information needed on the specific query.

Cover the whole query in its entirety at a heading level (is your paragraph the best answer to your H2)

If you are not covering the whole query in its entirety you are simply not ambitious enough to dominate for the specific search term.

Is each section of a page the best content on the internet? Can we rank #1 for every h2 by supplying the best information?

Google has now released a statement to say they are releasing google passages where if your heading section existing  content is the best answer to the search query they will start to rank these passages no matter how powerful the whole page is.

Google will begin passage-based indexing later this year for English languages. It is a ranking change, not an indexing change. Passage-based indexing updates. “Very specific searches can be the hardest to get right,” said Google, “since sometimes the single sentence that answers your question might be buried deep in a web page. We’ve recently made a breakthrough in ranking and are now able to not just index web pages, but individual passages from the pages. By better understanding the relevancy of specific passages, not just the overall page, we can find that needle-in-a-haystack information you’re looking for.”

It’s important to remember if you change the query you put into SurferSEO SERP Analyzer this can help you expand missing phrases to get onto the page for each specific heading section.

Try to look at ways to write concisely to grab the featured snippets for every H2 or H3 on your pages. Check this video on how to write the content as directly as possible under the subheading.

Can you honestly say you have explained the h2 header information the best you possibly could? If no then expand the content until you say this is the best answer in a concise writing style.

Missing Subheadings Using SEO Minion

Steve Toth at SEO Notebook recently gave an amazing strategy to do content expansion at a page level here.

I added 200+ clicks a day to two existing blog posts (just to prove it wasn’t a fluke).

  1. GSC: find a keyword with the highest clicks and impressions. In both cases, we were average position 2-3.
  2. Google the keyword and open all 10 pages in separate tabs. Note the headings (I use SEO Minion Chrome Extension to scrape them).
  3. Dump them all into a spreadsheet, filter by H2 and H3.
  4. Now compare them to the headings you already have and select 3-5 topics that you haven’t covered (check the volume or use intuition).
  5. Rephrase those headings and write 200 words for each of those topics, I make them H2s.

I even stuck these new sections at the bottom of the article and it still worked.

The build-out of a bunch of post-publishing optimization processes can grow your organic reach for existing articles 10 fold.

Missing Subheadings Using AhRefs

Here is a video to show how you can do this using the Ahrefs Chrome Extension:

Keyword Usage Missing Phrases Using Google Search Console

Google Search Console has the most valuable data of your search traffic with information on queries, impressions, and clicks to your website.

You can get the information you need to rank straight from Google Search Console to then optimise your content better with progressive optimisation.

The SEO Testing Tool allows you to connect to the GSC API and shows you phrases you are ranking for but it is not even mentioned on the page:

Being able to Identify Missing Phrases To Add Within Your Content Using SEOTesting is an amazing content expansion Search Engine Optimization hack.

Why is Google Search Console amazing for Content Expansion ideas?:

  • Shows impressions for phrases your page is showing up for which might not even be mentioned on the page yet
  • Shows clicks for keywords to your page which might be the wrong page and got to create a new post for a different corpus query
  • Shows content cannibalisation issues where a few URLs are showing up for the same keyphrases
  • Brings to your attention queries that you never came across in your keyword research studies

Imagine having a system where within your dashboard on WordPress you can be informed about queries you show up for that are not even mentioned on a page?

Well, this is now available by Dusan who has created a plugin called and here is my Impressionz Review on why we included this to our post-publishing optimisation SOP processes.

Using Bolded Keywords From Google SERP

The bold words in Google SERP when you carry out a search are a massive signal you should use for optimizing your content.

Extracting and scraping the bolded keywords in Google SERP descriptions can help improve the relevance of blogs.

Here is how we scrape and extract all the bolded words from the Google Search Engine Results Page.

Using People Also Ask Questions

People Also Ask are questions that search engines, such as Google tells you gets searched and is related to the query you have just searched.

So adding these PAA questions into your content is a great way to expand the content on your website.

Once you have exported all the questions to ask and answer on your website then matching those to meet the SERP intent is important for it matches the one page for one corpus strategy.

You are probably wondering how can we scale the PAA content expansion with slick processes?

SEO Minion has become my go-to SERP extraction tool as of late. One of my favourite features is the People Also Ask extraction.

It’s better than a lot of the other tools I’ve used because it doesn’t just get the question, it gets:

  • The question
  • The snippet answer
  • & the URL

That last one, the URL is the key to this next hack. Just follow these steps set out by Ste Toth.

In short, put “what is” in front of your keyword and you will generate lots of people also ask questions.

Trigger People Also Ask Queries

After you’ve installed SEO Minion chrome extension look for it on the right-hand side of the SERP:

SEO Minion PAA Extraction

Once you click to go the PAAs will start expanding like mad.

After it’s done you will have 200 questions, snippet answers and URLs in a sheet.

Work through the 200 related questions and decide whether to add into existing articles you have at present to expand the copywriting at a page level. Or if there is new SERP intent you have not yet covered then create a new post to cover this topic.

Check an example here explaining the process to my team to expanding content for questions and answers topics:

Most of the time the People Also Ask questions are going to show zero search volume and I can tell you that many of the blogs I have has 0 search volume for the PAA, but still brought in a massive amount of traffic.

Using Google Suggest

Google Autosuggest Suggestions are a vital way for customers to get the exact search that they want, but what if we told you that you can use this feature to help improve your content?

This tactic of adding an asterisk to trigger keyword stretching helps massively with content SEO and keyword stretching SEO.

The Q&A style website brings up some amazing ideas that generic research for keywords would not bring to fruition.

Moz Using From Prompt to Paragraph

You are tasked with getting great content written well and quickly.

Check out how to get started with content briefs with the prompt to paragraph style strategy.


Marketmuse provides great content briefs and questions for new articles to be written.

Write up on every possible subtopic to do with your niche so there are many articles internal linking and creating a nice silo structure throughout your domain.

Can your page rank for more phrases than it currently is on the same corpus set of words?

Expanding the content to be the most in-depth informative post will get the readers to stay on your page longer.

User experience on your pages is important so it has got to match the intent of the search query!!

Treat each subheading as its own article and ask yourself is this the best piece of content to deliver the information on the internet – if no then improve it.
