How Grammar Affects User Experience

Grammar might not be top of mind when you’re designing a user experience, but it should be up there. A small typo, a grammatical error, or a misworded sentence can have a detrimental impact on an experience and prevent the onboarding of a new user.

At its core, grammar and spelling are communication tools that are fundamental in the establishment of trust between a user, a product and a brand. Proper grammar denotes authority, intelligence and credibility, and the absence of it can drive users away from your site, not to mention cost your company big money. An omitted hyphen is said to be the culprit behind a rocket explosion that cost NASA $80 million in 1962 (equivalent to more than $640 million today). More recently, a missing comma cost a dairy farm in Maine $10 million in a class action lawsuit.

Grammar, UX and SEO

While these are big-ticket examples, small typos and grammatical errors can have major consequences too. Users report that grammatical errors make them question the attentiveness of the company. One user said that if a company can’t take the time to check for spelling, they likely wouldn’t take the time for the customers either.

A general rule of thumb: if it matters to users then it matters to search engines too.

This means that grammatical errors not only affect your users’ experience, but also the page ranking of your website.

Matt Cutts, the former head of the web spam team at Google, said, “We noticed a while ago that, if you look at the PageRank of a page (how reputable we think a particular page or site is) the ability to spell correlates relatively well with that. So, the reputable sites tend to spell better and the sites that are lower PageRank, or very low PageRank, tend not to spell as well.”

Duane Forrester, Sr. Product Manager at Bing echoed these sentiments.

“…just as you’re judging others’ writing, so the engines judge yours. If you struggle to get past typos, why would an engine show a page of content with errors higher in the rankings when other pages of error free content exist to serve the searcher? Like it or not, we’re judged by the quality of the results show. So we are constantly watching the quality of the content we see,” he said.

Does bad grammar equate to a bad user experience?

The wrath of grammatical errors extends far beyond search engine page rankings and bounce rates. Grammar mistakes and bad spelling can also:

Users are people and people make judgment calls. Don’t let something as easy to correct as grammar and spelling be the reason your users don’t give your website or application a chance.
