Note that the higher the overall literacy of your target audience, the more competent and literate the websites texts should be. And you cannot earn trust of your prospective customers allowing mistakes in the profile content directly related to the company’s area of activity. People will hardly believe in your attention to details and professionalism if they see mistakes on the main page of your website.
Customer loyalty metrics used in SEO analytics reflect the way the users react to your content. Any significant changes in the content of the pages lead to changes in the key figures. Literate, quality content results in increasing number of pages that users view on the website. Users also tend to spend more time on each page if the website content is well-written and engaging. Behavioral factors directly influence the search ranking, so the interrelation is obvious – allowing errors on the website you lose both customers and SERP rank.
Spelling of keywords
If keywords on a web page are misspelled, the potential customers will not be able to find you, as search engines will not display your website in SERP. Moreover, during website indexation search engines bring keywords back to the initial word forms. Misspelled words can be brought back to the initial word forms incorrectly, and this will reduce the text relevance to search queries. Keep in mind that bots do recognize errors on the site and even know how to correct them (that’s why search engines can automatically correct misspelled words). Therefore grammatical errors can drop the website in search rankings. And vice versa, correctly spelled keywords help users to find your website.
