Old outdated content damages your ranking on Google. Deleting old, bad or unranked pages will improve your website. If you have old content that’s isn’t great – it’s no value to your visitors. Google ranking likes good, useful content and can penalize you for bad content.
The solution – either delete it or update it. Google is looking for EAT – which is the best content for each topic.
You should be reviewing your old content on a regular basis to ensure it is still current and useful to your site visitors. It can be better to update old content instead of writing brand new content. Updating pages with the latest information on a topic is a good idea. Google recommends you update your pages to keep them relevant.
Old pages have some value as they will have age authority. If you can add more value or page juice to that page it can improve your ranking dramatically. – And its easier than working on new content.
