Is SEO a Grammar Nazi?

This time we focused on the Croatian market, where searches are mainly conducted in the Croatian language via Google.hr, and our famous SEO ( Search Engine Optimization ) plays a crucial role in visibility.

Based on available data and research, as well as expert opinions, we investigated how content irregularities affect SEO, user experience, and overall marketing results.

The results clearly show that the errors are not only of a cosmetic nature and fodder for the so-called Grammar Nazis , already in the real competitive business world , can ultimately reduce traffic by up to 70% and increase the bounce rate (abandonment rate) up to a terrifyingly high 85% .

Impact on SEO: Direct and indirect mechanism

Google’s algorithm does not directly penalize errors in spelling or grammar as a direct ranking factor , but they have a strong indirect impact through user experience (UX) and visitor behavior. Figuratively speaking, when the Google sniper “misses” you, you run into infantry that runs over you.

In order to give you a clearer idea of ​​what this is all about, take a look at the key mechanisms used primarily by Google when ranking individual content/pages:

• Content Readability and Indexability : Errors make it difficult to understand, which can confuse Google’s bots (those are the bots we want on the page) when crawling. If the content is not clear, the algorithm may rank it lower because it considers it not “high quality”. For example, Bing (less relevant in HR, but similar principle) explicitly penalizes spelling mistakes when ranking .
• User Behavior : A high bounce rate and low dwell time (time spent on a page) signal to Google that the content is poor, which leads to a drop in rankings. According to research by Website Planet (which tracked over 5,000 visits to different pages), pages with errors have an 85% higher bounce rate than those without spelling or grammatical errors. This directly affects SEO because Google prioritizes pages with high engagement.
• Loss of backlinks and authority : Poor content reduces the likelihood that other websites will link to it, because it looks unprofessional. Backlinks are key to EAT ( Expertise, Authoritativeness, Trustworthiness ), which is especially important in HR where local authority plays a significant role.

For our market, where the Croatian language is specific (with diacritical marks such as č/ć, dž/đ), errors such as “kuče” instead of “kuće” or the even worse tipfeler “to kill” instead of “in essence” (a frequent occurrence on social networks, according to Reddit discussions) significantly damage credibility, or in some situations lead to a basic misunderstanding of what the text or publication is actually about.

Impact on marketing actions: Loss of trust and conversion

Illiterate content not only reduces SEO, but also overall marketing results, especially in our country where consumers prefer local, reliable brands (btw. this is also the case in other “small” countries that are geographically classified in a less developed part of Europe):

• Loss of trust : According to global statistics, 70% of users are less likely to click on an ad or page with errors.
• Decreased traffic and conversions : Pages with errors get fewer visits and lower rankings, leading to a loss of organic traffic. In HR, where 81% of users look for services locally , this means significantly fewer leads .

• Impact on social networks and AI : Content is often shared on social networks, where mistakes quickly go viral (eg Reddit examples of “no-no-no” or copied articles). Google’s AI Overview (2025) further favors clean content, so errors can reduce visibility in AI results.
