SERPIQ conducted a study that found that websites in the top ten of Google’s search results have an average content length of over 2,000+ words:
Those WebSites that rank number one have an average content length of 2,500 words, and sites that come in tenth have an average word count of 2,000. This shows that there is a slight drop in page rank as the word count reduces.
Longer content (if interesting and engaging) tends to attract more backlinks and it helps good position yourself as a Web authority. It also gives you additional opportunities to rank for long-tail keywords and increases the amount of time people spend on your website, which is another factor Google takes into account when ranking content.
Regardless of your domain age or your authority ranking, you can reap the benefits of long-form content by creating something that is 10x better than anything else already out there on a topic. This will help you stand out, not only to Google but also to your customers and reducing bounce rate.
Try to include stories, visuals and a variety of media in your long-form content. You need to engage readers for a long period and ideally make them want to check out other pages on your site.
The goal with long-form content is that your readers will have everything they need from that topic when they finish reading, and won’t need to look elsewhere.
