Google PageRank is determined by several factors, including the quality of content. One of the consistencies found in low quality content is incorrect spelling and typographic errors. Poorly developed content carries little useful and meaningful information and will never be regarded as expert content. Poor content can also result in a higher bounce rate (an increased likelihood of a user leaving the page quickly) and fewer high quality backlinks which can result in lower rankings in search engines.

While it is true that not all pages with misspellings or grammar problems are poor quality, and not all poor quality sites have numerous grammatical and spelling errors, there is still evidence that poor quality text that provides minimal value to the reader is indicative of low-value content. For this reason, ensuring that your website copy is free of spelling errors, is easily understood, and utilizes proper grammar, can improve the overall user experience on your website.
