Providing a good website to your visitor also benefits your search engine rankings by creating user friendly interface and unique content that really attracts customers. Research show that there is a high correlation on how search engines rank a site based on user experience.
Search engine worthy websites
Page clutter – improve user experience by reducing page clutter. You want your visitors to be focused on a single goal on your site and additional page clutter can interfere with potential conversions. Full width images, unnecessary headings and affiliate links can make your content less scannable which can cause your visitors to exit your site or move to another page.
Page design – it is everything that a visitor sees in your website, images, use of color accents, placement of text and images, and links are all connected to page design. Remember, your website is considered an extension of your company that also demonstrates your brand.
Text layout – instead of placing all your content into one paragraph, studies show that it’s better to break it up into smaller parts for readability purposes. The layout such as text wrap, width of wrap around text, using bullet points are considered tweaks on the layout of your text. Bottom line is that your content must have structure, it should have introduction, middle and end part and each section should have a heading.
Navigation – your website should have proper navigation to guide your visitors easily thru a conversion path. It is best to take time and think how your customers would access your products from the home page and giving them what they are looking for quickly. Visitors having a hard time locating your product could instantly leave your site and not come back at all.
