Section 1
Confusion does not ask questions, it leaves
On a sales call, a confused prospect raises an eyebrow and you rephrase instantly. Your website gets no such mercy. Nielsen Norman Group's foundational reading research found that 79% of web users scan rather than read, picking out individual words and phrases, which means your visitor is not parsing careful sentences but pattern-matching keywords against their own problem. If your page says 'integrated revenue operations enablement' and the buyer's internal monologue says 'my leads fall through the cracks,' the pattern match fails and they bounce. No one emails to ask what you meant. The scan-based reality also explains why jargon damages exceeds its word count: scanning eyes land precisely on the prominent nouns, headlines, subheads, buttons, which is exactly where insider vocabulary tends to concentrate. The most-seen words on your site are often the least understood. If you are turning this into practice, [The Web Design Mistakes That Quietly Cost Service Businesses Clients](/blog/web-design-mistakes-that-quietly-cost-service-businesses-clients) maps the adjacent system.

Where insider language hides on a service site
Jargon is easy to condemn and hard to see in your own writing, because every term reads as ordinary to the person who uses it daily. Chip and Dan Heath named the mechanism the curse of knowledge: once you know something, you cannot readily re-create the state of mind of someone who does not. The practical antidote is knowing where to look. Jargon concentrates in predictable places, each with a predictable repair. The table below maps the four habitats we find most often in service-business audits. Work through them in order, navigation and headlines first, because scanning visitors meet those words before any explanatory sentence gets a chance to rescue them.
Section 3
Why expertise writes worse copy than curiosity
The curse of knowledge means the more elegant your internal shorthand becomes, the worse your public copy gets, not despite your expertise but because of it. There is a second force too: jargon feels like a credential. Founders worry that plain language will read as unsophisticated, so they armor the copy with terminology meant to impress peers. But your website's reader is not a peer; it is a buyer making, in Harvard Business Review's jobs-to-be-done framing, a hiring decision about progress they need to make in their own life or business. Buyers describe that progress in plain words: stop losing leads, pass the audit, get the books done. Sophistication that obscures the match between their words and your offer is not positioning, it is friction wearing positioning's clothes. Plain language is what confident expertise sounds like in public.

Section 4
The translation process: mine calls, rewrite, read aloud
Do not brainstorm simpler words, harvest real ones. Pull recordings or notes from your last ten sales conversations and list every phrase prospects used to describe their problem, their goal, and their hesitations. That list is your site's new vocabulary. Rewrite in three passes: first replace every navigation label and headline term that does not appear on the list; second, rename services descriptively even if the official name stays as a subtitle; third, read every page aloud and flag any sentence you would never say to a prospect's face. Test with one outsider: if they can restate what you sell and for whom, you pass. This vocabulary-first rewrite is standard sequence in ConvertOS engagements, buyer language is locked before layout, because design can only amplify words people understand.
