Competitor Keyword Gap Analysis

You've built a decent website, written your service pages, and told everyone to Google your business. Then you search for what you do, and three competitors show up before you do. You have no idea why they're there and you're not. Sound familiar? Most small business owners hit this wall at some point. The good news is you don't need to guess your way through it. A keyword gap analysis shows you exactly which search terms your competitors rank for that you don't, so you can see where the gaps are and what to do about them. This guide walks you through it without any of the confusing jargon.

What a Keyword Gap Analysis Actually Shows You

Think of it like comparing shopping lists. You and a competitor might sell similar things, but their list has items yours doesn't. Doing a keyword gap analysis means comparing the search terms your site ranks for against the ones your competitors rank for. Whatever's missing from your list is a gap you can fill.

These gaps usually fall into a few groups, and it helps to know which type you're dealing with before you decide what to do next.

Once you know which type of gap you're looking at, deciding what to fix first becomes a lot more straightforward.

Why Competitor Keyword Research Matters for Small Business

When I had my own trade business, I used to think this sort of thing was only worth worrying about if you were a big company with a marketing budget. Then I noticed competitors showing up for searches I hadn't even thought of, and I realised they weren't smarter, they'd just done the homework.

When it comes to competitor keyword research, the reason it matters is simple: your customers are already searching for what you sell. If a competitor ranks for terms you're missing, they're getting the enquiries that could have been yours. This isn't about copying anyone. It's about making sure your website isn't invisible for the searches that actually bring in business.

How to Find Competitor Keywords

The process of finding competitor keywords sounds harder than it is once you know where to look. You've got two main options: doing it manually, or using a tool to speed things up.

The manual way starts with a plain Google search. Search for the products or services you offer and note which competitors keep showing up. Open a few of their pages and look at the words they've used in headings, page titles, and body text. Scroll down and check the related searches at the bottom of the results page too, since these often reveal terms you hadn't thought to search for yourself.

The faster way is to use a tool such as SEO Analyser, where you enter a competitor's website address and get a list of the terms they rank for, often alongside search volume (roughly how many people search that term each month) and ranking difficulty (how hard it would be to rank for it, based on who's already on page one). This saves you the hours it would take to piece the same picture together by hand.

Picture a small bakery in Fremantle. A manual search shows a bigger competitor ranking for "gluten free bread Fremantle" and "custom celebration cakes Perth." Running that same competitor through a keyword tool confirms both terms, plus a few more the bakery owner hadn't thought to search for, like "wedding cake tastings Perth." Comparing that list against the bakery's own website makes three clear gaps obvious.

Whichever method you use, the goal is the same: build a list of the terms your competitors are winning with, then compare it against your own site so the gaps stand out.

Running a Content Gap Analysis on Your Site

Rather than comparing single keywords, a content gap analysis looks at the bigger picture. It's like comparing your shop shelves to a competitor's shelves, not just the price tag on one item.

Start by listing the main topics your competitors cover across their blog and service pages. Then check whether your website covers the same ground. If a competitor has a detailed guide on choosing a hot water system, and you only mention it in one line on a services page, that's a content gap worth closing.

This matters because Google tends to reward sites that cover a topic thoroughly, using related terms and answering the questions people actually have, rather than sites that mention something once and move on. Closing a content gap often means expanding a page you already have, not necessarily starting from nothing.

Don't worry if this feels like a lot of extra writing. You don't need to match every competitor topic for topic. Focus on the gaps that relate directly to what your business genuinely offers.

Prioritising Which Keyword Gaps to Target First

Once you've found your gaps, you'll probably end up with a long list. Trying to tackle all of it at once usually means none of it gets finished. It helps to run each gap through a few quick checks before deciding where to start.

• Does the keyword match what your business actually sells or offers?
• Is the search volume high enough to be worth the effort?
• How difficult would it be to rank for, based on who currently sits on page one?
• Does it match buyer intent, meaning the person searching is likely ready to enquire, rather than just browsing?

Keywords that tick most of these boxes are your quick wins, the gaps worth tackling first because they offer a realistic chance of ranking without months of waiting. Keywords with high search volume but heavy competition from national brands are usually better left until your site has more runs on the board.

Common Mistakes in Competitor SEO Analysis

The biggest mistake I see is business owners comparing themselves to the wrong competitors, usually national brands with years of on-page SEO work behind them (on-page SEO is everything you do on your own pages, like headings and content, to help Google understand them). Comparing a local business to a national chain rarely produces a fair or useful gap list.

Another common mistake is copying competitor content word for word instead of understanding why it works. Google can tell when content is duplicated, and it won't help your rankings. Use what you learn about their topics and terms as a starting point, then write it in your own words, based on your own experience with your customers.

Turning Keyword Gaps Into Content

Finding a gap is only half the job. The other half is turning it into a page or post that actually answers what people are searching for.

Start with the gaps you've decided are quick wins. For each one, write a page or post that directly answers the search term, using natural language rather than repeating the exact phrase over and over. Add internal links (links from one page on your site to another) between the new content and related service pages, so both Google and your visitors can find their way around easily.

Think about search intent too, meaning what the person actually wants when they type that search in. Someone searching "hot water system repair cost Perth" wants pricing information, not a history lesson. Match your content to what they're actually after, and you'll hold their attention long enough for them to consider getting in touch.

Tools That Make This Easier

You don't need to be a tech expert to run a competitor SEO analysis. Tools such as SEO Analyser let you enter a competitor's website and see the keywords, topics, and pages they're ranking for, without needing to understand the technical side of how search engines work.

Google Search Console is worth checking too, since it shows you the search terms your own site already gets clicks for, which makes it easier to see where your gaps actually sit. Between the two, you'll have a clear picture without spending money on expensive agency reports.
