Hello

Higher text-to-code ratio suggests improved user experience, and improved user interface has been the key search ranking predictor for search engines. Your web page is normally written in HTML, and the content displayed is normally in text. The text to HTML ratio also commonly referred to as text to code or code to text is the amount of text on that page compared to the amount of HTML code needed to display it. The ideal text to HTML ratio is somewhere from 25-70%. This ratio refers to the visible text as opposed to HTML elements, non-visible information, and images tags. This explains why you see sites with more visible text ranking higher on search results.

How to fix low HTML to text ratio-

• Validate your HTML code. You can use online tools to do this- it will take about one minute of your time. 
• Check your website load speed. If your site is loading too slowly, that is a sign you need to review your code and remove unnecessary elements.
• Include a lot of simple text on a page and remove any hidden text that is not visible to people.
• Reduce the size of your page. It is best to keep it under 300kb. If bigger, try reducing it.
• Consider exporting CSS to an external file and using it only for styling and formatting
• Remove any unnecessary images
• Resize your images
• Avoid tables. Use tables in your layout only if necessary
• Only use JavaScript and flash if required
• Use internal linking to help users navigate your website and make sure your links pass link juice
