Google wants to see the average user staying on your site for a good length of time, as well as visiting other pages. Make sure your content quality supports this! Keep in mind that visual content like videos and photo slideshows, along with interactive content like quizzes and surveys, are more likely to go viral and bring in a lot of traffic, as well as getting people to spend more time on your site.
Make sure you include relevant images in your articles, too. Images are vitally important these days. Not only do they make your article more interesting to visitors, but they provide a great way to let people share your content on social media and bring you more traffic. If you don’t include relevant images, you won’t see anything show up on social media, or you’ll see only your site’s logo or background, which could be worse than having no image at all.
