Content-Length is about how many words are included in your content..

Longer content (over 1000 words) performs better in Google, but this is not always the case, it depends on the kind of page and if we can add more content to it.

Content repurposing is the process of adapting or modifying existing content so that it can be used in a) a new format or b) for a different audience. This can be done for a variety of reasons, such as to reach a wider audience, to update or create content for another medium, or to create new content more efficiently.

There are many ways to repurpose content, depending on the original format and the intended new format. For example, using specialized apps, a blog post could be turned into a video, a podcast, or a social media post. An infographic could be turned into a slide deck or a series of blog posts. A webinar could be turned into a series of blog posts or a video course.

Content repurposing can be a useful strategy for content marketers and other professionals who want to make the most out of their existing content assets.
By repurposing content, they can reach new audiences and extend the life of their content, without having to start from scratch every time they want to create new content.

Duplicate content can be identified as low-quality pages that add little to no value to the reader.

Headings structure the entire page. For your readers, for google for everyone.
They’re important for readability, but for SEO as well. Headings help Google to grasp the main topics of a long post and therefore can help in the ranking. The H1 tag is the most important heading because it’s the highest level tag that shows what a specific page is about. Search engines give this tag more weight over other headings.

Meta description is the additional text that appears in your search results that lets you know what the link is about. Meta Descriptions should tell audiences what they can expect to find on your page and should work to persuade those users to click through.
The optimal length is 140-170 characters. They have a lot of value in terms of SEO. Make every word count!
