How to do keyword research for a NZ business

Why keyword research matters (and what happens without it)

Keyword research answers the most fundamental question in SEO: what should you create content about? Without it, you're guessing what your customers search for. With it, every page on your site targets a specific phrase that real people type into Google.

Here's what happens when NZ businesses skip keyword research: they write a service page titled "Our Services" (nobody searches for that), they target "plumber" (too broad, impossible to rank), or they blog about topics no one is looking for (zero traffic, wasted effort). Every guide on this site - from our on-page SEO checklist to our local SEO guide - assumes you've done keyword research first. It's the foundation everything else builds on.

Why NZ keyword research is different

Most keyword research guides are written for the US market - a country with 330 million people and fierce competition for every keyword. NZ has 5 million people. This changes everything:

Search volumes are much smaller. A keyword that gets 50,000 searches/month in the US might get 200 in NZ. This is not a problem - it's an advantage. Lower volume means lower competition, which means faster ranking.

NZ language is different. We say "tradies" not "contractors," "bach" not "vacation home," "jandals" not "flip flops," "ute" not "pickup truck." If your keyword research uses American terms, you're targeting words Kiwis don't type.

You must set tools to NZ. Every keyword tool defaults to US data. If you research keywords without switching the country to "New Zealand," every volume figure and difficulty score is wrong. This is the single most common keyword research mistake NZ businesses make.

Local modifiers matter more. "Plumber" is useless. "Plumber Ponsonby" is a money keyword. NZ's geographic specificity - suburbs, cities, regions - creates thousands of rankable local keyword variations that don't exist in larger markets.

Step 1: Brainstorm seed keywords

Before opening any tool, write down 10-20 seed keywords from your own knowledge. These are the broad starting points you'll expand on:

Think like your customer. What would someone type into Google if they were looking for what you sell? Not your industry jargon - their words. A customer doesn't search "residential plumbing solutions" - they search "plumber near me" or "fix leaking tap."

List every service or product. Write down every specific thing you offer. A plumber might list: blocked drains, leaking taps, hot water cylinder repair, bathroom renovation, gas fitting, burst pipes, emergency plumber.

Check competitor websites. Look at the menu, service pages, and blog of your top 3 NZ competitors. What terms do they use? Their page titles reveal their keyword targets.

Ask your customers. What do they say when they call? "I found you when I searched for..." is the most valuable keyword research data you can get.

Step 2: Expand with free tools

Take your seed keywords and use these free methods to discover hundreds of related terms your NZ customers actually search for:

Google Autocomplete (free, instant)

Type your seed keyword into Google and look at the suggestions before you hit enter. "Plumber Auckland" autocompletes to: "plumber Auckland emergency," "plumber Auckland cost," "plumber Auckland North Shore," "plumber Auckland reviews." Each suggestion is a real search that Kiwis make regularly. Write them all down.

Repeat with modifiers: "how to [seed]," "best [seed] NZ," "[seed] cost NZ," "[seed] near me." The alphabet trick works too: type "plumber Auckland a" then "plumber Auckland b" and so on - you'll uncover long-tail gems.

"People Also Ask" (free, instant)

Search your seed keyword and scroll to the "People Also Ask" box. These expandable questions are exactly what your NZ customers want answered. Each question is a potential blog post or FAQ section on your service page. Click a question and more appear - you can generate 30+ topic ideas from a single search.

Google Keyword Planner (free, requires Google Ads account)

Create a Google Ads account (you don't need to spend money). Go to Tools → Keyword Planner → "Discover new keywords." Critically: set location to "New Zealand" before running any search. Enter your seed keywords and it returns related terms with NZ search volume ranges (e.g., 100–1K) and competition levels.

The volumes are ranges, not exact numbers - but they're directionally useful for identifying which NZ keywords have enough search volume to be worth targeting. Export the full list to a spreadsheet for analysis.

Google Search Console (free, your actual data)

If your website is already live, Search Console is a goldmine. Go to Performance → Search Results and look at the queries driving impressions. Filter for queries where your average position is 8-20 (page 2 or bottom of page 1). These are your quick wins - pages that already rank close to page one and need a small on-page push to break through.

You'll also discover keywords you didn't know you were ranking for - unexpected phrases customers use that you never thought to target. These insights are unique to your site and more valuable than any paid tool.

Step 3: Understand search intent

This is the step most NZ businesses skip - and it's the reason their pages don't rank even when they target the right keywords. Every search has an intent - the reason behind the search. Google ranks pages that match intent, regardless of how well-optimised they are.

The test: Google your target keyword and look at the top 5 results. If they're all blog posts, Google thinks the intent is informational - your service page won't rank there. If they're all service pages, a blog post won't rank. Match your content type to what's already ranking.

Step 4: Evaluate difficulty and opportunity

Not every keyword is worth targeting. You need to evaluate whether you can realistically rank for it - especially in the NZ market.

Check who's currently ranking. Google your keyword and look at the top 10 results. If they're all massive sites (Trade Me, Stuff, government sites, Wikipedia), the keyword is probably too competitive for a small NZ business - at least for now.

Look for weak results. If you see forums, outdated articles, thin content, or small businesses with unoptimised pages in the top 10 - that's your opportunity. You can create something better and outrank them.

Use keyword difficulty scores wisely. Tools like Ahrefs, Semrush, and SE Ranking assign difficulty scores (0–100). For NZ small businesses, target keywords with difficulty under 30 initially. Once you build domain authority over 6-12 months (see our timeline guide), you can tackle harder keywords.

NZ advantage: keywords that score 60+ difficulty in the US often score 20-30 in NZ because fewer sites compete for them. Always check difficulty with the country set to New Zealand.

Step 5: Prioritise by commercial value

A keyword with 10,000 searches/month that generates zero revenue is worthless. A keyword with 50 searches/month that brings in paying customers is gold. Prioritise by revenue potential, not volume.

CPC as a proxy for value. Check the cost-per-click in Google Keyword Planner. Keywords with high CPC ($5 - $30+) attract advertisers because they lead to revenue. If advertisers are willing to pay $15 per click for "family lawyer Auckland," that keyword is extremely valuable for organic rankings too.

Step 6: Map keywords to pages

Once you have your prioritised list, assign each keyword to a specific page on your website. This is called keyword mapping - and it prevents the common problem of multiple pages competing for the same keyword (cannibalisation).

The rules: one primary keyword per page. 2-3 closely related secondary keywords per page. Every important keyword gets its own dedicated page. Never target the same primary keyword on two different pages.

For a plumber in Auckland, the map might look like:

• Homepage: "plumber Auckland"
• Emergency page: "emergency plumber Auckland"
• Ponsonby page: "plumber Ponsonby" (secondary: "emergency plumber Ponsonby," "blocked drains Ponsonby")
• Grey Lynn page: "plumber Grey Lynn"
• Pricing page: "plumber cost Auckland" (secondary: "how much does a plumber cost NZ")
• Blog post: "how to unblock a drain" (secondary: "DIY drain unblocking NZ")

Long-tail keywords: the NZ secret weapon

Long-tail keywords are longer, more specific phrases - "emergency plumber Ponsonby weekend" vs "plumber." They have lower individual volume but convert at 2-5x higher rates because the searcher has a specific, immediate need.

In NZ's smaller market, long-tail keywords are your biggest opportunity. "Plumber Auckland" has maybe 2,000 searches/month and is fiercely competitive. "Emergency plumber Ponsonby weekend" has 20 searches/month - but every one of those searchers is picking up their phone to call the first result. And with low competition, you can rank for it in weeks, not months.

The maths: ranking for 50 long-tail keywords at 20-50 searches each gives you 1,000-2,500 visitors/month - the same as ranking #1 for a single broad keyword, but with much higher conversion rates and a fraction of the competition.

Local keyword strategy for NZ businesses

If you serve customers in a specific NZ city or region, local keywords are your bread and butter. The formula is simple: [service] + [location]. Create a dedicated page for each combination you want to rank for.

An Auckland tradie might create pages for: Ponsonby, Grey Lynn, Mt Eden, Parnell, Newmarket, Remuera, Epsom, Takapuna, Devonport, and Mission Bay - each targeting "[service] + [suburb]." That's 10 rankable pages from one service offering, each capturing a different geographic search.

Important: each suburb page needs unique content - not just the suburb name swapped in with otherwise identical text. Google detects and demotes doorway pages. Include suburb-specific details: landmarks, common property types, local issues (e.g., "Ponsonby's older villas often have lead piping that needs replacement").

5 keyword research mistakes NZ businesses make

1. Using US data

Forgetting to set tools to "New Zealand" means every volume figure and difficulty score is wrong. A keyword showing 10,000 searches/month globally might have 80 in NZ. Always filter by country.

2. Targeting only broad keywords

Going straight for "plumber Auckland" or "lawyer Wellington" without building topical authority through long-tail keywords first. Start specific, build authority, then go broad.

3. Ignoring search intent

Building a service page for an informational keyword or a blog post for a transactional one. Google your keyword first and check what type of content currently ranks - then match it.

4. Chasing volume over value

A keyword with 5,000 searches/month and zero commercial intent is worth less than one with 50 searches/month where every searcher is ready to buy. Prioritise by revenue potential.

5. Doing keyword research once and never again

Search behaviour changes. New terms emerge, seasonal patterns shift, and competitors move in. Review your keyword strategy every quarter. Check Search Console monthly for new opportunities you're accidentally ranking for.
