Infographic is something that can turn a complex or dull subject into a captivating experience. They are easily digestible bits of content that help to get your message across in the best possible manner. The first and foremost step in optimizing an infographic is to make sure the content supports a keyword phrase. Ideally, when people search for that particular keyword or phrase, your content will be the first thing they see.
Make sure to include the word “infographic” in your H1 title tag and H2 subheading that you place directly above your infographic. The keyword phrase should be clearly placed within your post’s URL, as it’s an essential element that search engines use for ranking. Add a compelling Meta description and also include the keyword there. Search engines like long-form content, especially if they are optimized correctly. Try to create content to at least 1,000 -2000+ words, and make sure you include keywords throughout. Check out this SE Ranking infographic to know how to optimize infographics for search traffic.
