Content Gap Analysis
Content MarketingAlso: Content Gap Audit · Topic Gap Analysis
Quick definition
Content gap analysis is the process of comparing your existing content against what your audience searches for and what competitors already rank for, to find topics you haven't covered. It surfaces missing pages, thin coverage and keywords worth targeting that would otherwise go unnoticed.
How it varies across Australia
Australian businesses in competitive categories like finance and ecommerce typically carry more content gaps than global averages, mostly because content was written for launch and never mapped against a full keyword set. The gap is usually widest at the consideration stage, not the top of funnel.

A subject your audience searches for that you haven't published anything on.
You've covered the topic but missed the specific terms people actually type in.
The query wants a comparison, calculator or list and you've only got prose.
Your page answers a different question than the one the searcher is actually asking.
What it actually means
Imagine mapping every room in a house you're selling, then walking through a competitor's open home next door and noticing they have a study, a second bathroom and a proper laundry, and you don't. Content gap analysis is that walkthrough, done with search data instead of floor plans.
The process starts with a full inventory of your content, then a matching inventory of what ranks for your target keywords, usually pulled from a rank tracker or a competitor's sitemap. Anywhere a competitor ranks and you don't, or ranks higher for the same query, that's a gap.
Gaps come in different shapes. Some are missing topics entirely. Some are thin pages that exist but don't answer the query properly, which overlaps heavily with content decay. Some are format gaps, where the query wants a comparison table or a calculator and you've only got a paragraph.
The output isn't a content calendar. It's a prioritised list, ranked by search volume, competitive difficulty and how close the topic sits to a conversion event. Not every gap is worth filling. Some are gaps for a reason.
A content gap analysis doesn't tell you what to write next. It tells you what your competitors already told Google they cover better than you.
How it shows up
Content gap analysis shows up as a spreadsheet cross-referencing your URLs against a target keyword list, usually built from tools like Ahrefs or SEMrush pulling competitor rankings. It also shows up informally whenever someone on the team says 'why don't we rank for that, we sell this exact thing.' Formally, it appears in quarterly content planning as the source document deciding what gets briefed next, sitting alongside a content audit that reviews what already exists and a content strategy that decides where the site is heading overall.
The Australian context
Global keyword tools built on US search data often miss Australian-specific search behaviour, particularly around local terminology, regulatory language and category names that differ from the US or UK. Running gap analysis against local competitors, not just global category leaders, usually surfaces more useful and winnable gaps for an Australian audience.

Common questions
How often should I run a content gap analysis?
Quarterly for competitive categories, twice a year otherwise. Search intent and competitor content shift faster than most teams expect, so a gap analysis older than six months is often already out of date.
What tools do people use for content gap analysis?
Ahrefs and SEMrush both have dedicated content gap tools that compare your ranking keywords against competitors. Search Console data and a manual competitor content audit work fine too, just slower.
Is content gap analysis the same as keyword research?
No. Keyword research finds terms people search for in general. Content gap analysis specifically compares those terms against what you and your competitors already have published, to find where you're missing or underperforming.
Should I fill every gap I find?
No. Prioritise gaps by search volume, competitive difficulty and proximity to a conversion event. A gap with low volume but strong buyer intent often beats a high-volume gap that only attracts browsers.
