Consider long-form content as 3,000-5,000 words. If you’ve got existing blog or email content that can be gathered into a treatise on a particular subject that your visitors and prospects are interested in, you can put it together on a single web page. Or, if you’ve got an e-book that’s been behind a gated form for a while, and you want to shift the value of that content from lead generation to search engine optimization, you can publish that content on a single web page.
