Keyword Translation: Why the Words You Use as an Expert Aren't the Words Your Customers Search For

You've spent years developing expertise in your field. You know the correct terminology, the industry-standard phrases, and the technical names for everything you do. And that expertise is almost certainly hurting your Google rankings — because your customers have no idea what any of those words mean.

The Expert's Curse: When Knowledge Becomes a Barrier

There's a well-documented psychological phenomenon called the "curse of knowledge" — first popularised by economists Colin Camerer, George Loewenstein, and Martin Weber in a 1989 study, and later made famous by Chip and Dan Heath in their book Made to Stick. The core idea is simple: once you know something deeply, it becomes almost impossible to remember what it was like not to know it.

For business owners and professionals, this manifests in a very specific way on their websites. They write in the language of their trade — and wonder why Google isn't sending them customers.

Consider a few real-world examples of the gap between professional language and customer language:

In each case, the professional term is perfectly accurate. But no real customer is typing it into Google. If your website only uses the professional terminology, Google will never match your page to the searches your customers are actually making — and you will be invisible to the very people you want to reach.

What Google's Own Data Tells Us

Google processes over 8.5 billion searches per day, and its Google Trends tool provides a remarkable window into how real people phrase their queries. When you compare professional terminology against plain-English alternatives, the search volume differences are often staggering.

Google's own search quality guidelines — the Search Quality Evaluator Guidelines — place enormous weight on what they call "query understanding." Google's systems are designed to interpret the intent behind a search, but they still rely heavily on lexical matching — the actual words on your page matching the actual words in the search query. If neither your page title, your headings, nor your body content contain the words a customer uses, no amount of technical SEO will fully compensate.

Rand Fishkin, founder of Moz , has written extensively on this topic, noting that the single most common keyword research mistake is "optimising for the terms we use rather than the terms our audience uses." It's a mistake that cuts across every industry and every size of business.

Search Intent: The Layer Beneath the Keywords

Understanding customer language isn't just about swapping technical terms for simpler ones. It requires understanding search intent — the underlying goal behind a query. Google classifies search intent into four broad categories, as outlined in its own content guidelines :

• Informational

  The searcher wants to learn something. "Why is my boiler making a noise?" or "What does a solicitor do?" These searches are best served by helpful, educational content — blog articles, guides, and FAQs written in plain English.

• Navigational

  The searcher is looking for a specific business or website. "Chichester Web Design" or "Smith's Plumbing Chichester." Brand and local visibility matter most here.

• Commercial Investigation

  The searcher is comparing options before making a decision. "Best web designer Chichester" or "how much does a new boiler cost." Service pages with pricing, reviews, and differentiators perform well here.

• Transactional

  The searcher is ready to act. "Book a plumber Chichester" or "web design quote." These high-intent searches require clear calls to action and friction-free contact options.

A common mistake is writing all website content in a transactional tone ("Call us today for your EICR!") while ignoring the informational queries ("do I need an electrical safety certificate?") that represent customers at an earlier stage of the journey — and that account for the majority of search volume.

How to Find the Words Your Customers Actually Use

The good news is that you don't have to guess. There are reliable, free methods for discovering exactly how your customers phrase their needs:

• → Google Autocomplete — Start typing your service into Google and watch what autocomplete suggests. These are real queries from real people. "Electrician Chi..." might autocomplete to "electrician Chichester emergency" or "electrician Chichester no call out fee" — revealing exactly what your customers prioritise.
• → "People Also Ask" boxes — The expandable questions Google shows beneath search results reveal the exact phrasings real users search with around your topic. These are an excellent source of FAQ content written in customer language.
• → Google Search Console — If your site is live, Google Search Console shows you the actual search queries people used before clicking through to your site — invaluable for identifying gaps between your language and theirs.
• → Reviews and enquiries — Read your Google reviews and old enquiry emails. The exact words customers use to describe their problem are the words you should be using on your website. If three different customers have written "my roof was leaking around the chimney," that phrase belongs on your page.
• → Answer the Public — Answer the Public is a free tool that maps out the questions and phrases people search around any topic. Enter your service and it generates dozens of real customer queries — all potential content opportunities.
• → Reddit and forums — Search Reddit or local Facebook groups for your service area. How do non-experts describe their problems? The raw, unfiltered language people use when asking for help online is extremely revealing.

You Don't Have to Choose Between Expert and Customer Language

The most effective approach isn't to strip out all technical terminology — it's to lead with customer language and bring in the technical terms as supporting context. This serves two purposes: it matches the search query that brought the visitor to your page, and it demonstrates your expertise once they're there.

For example, instead of heading a page "Periodontal Therapy Chichester," a dental practice might use "Gum Disease Treatment in Chichester" — and then explain within the page that this is also known as periodontal therapy. The customer finds the page. The professional terminology is still present for credibility. Everyone wins — including Google.

Brian Dean at Backlinko describes this principle as "seed keywords vs. long-tail keywords" — where seed keywords are the broad, plain-English terms your customers use, and long-tail keywords are more specific variations. A well-structured page targets both simultaneously.

A Practical Exercise for Any Business

Try this with your own website: read each page as if you're a customer who has never heard of your industry. For every technical term you encounter, ask yourself: "If I had this problem and knew nothing about the industry, what would I type into Google?"

Then search for both versions — the technical term and the plain-English alternative — in Google Trends. In almost every case, the plain-English version will have significantly higher search volume. And in many cases, it will have lower competition, because your competitors made the same expert-language mistake you did.

The businesses that close this gap between expert language and customer language consistently outperform their competitors in organic search — not because their websites are technically superior, but because they've taken the time to understand how their customers actually communicate.
