SEO Tips for Old Landing Pages and Blog Posts

Hi everyone,

I'm new to SEO and could use some advice on a few things:

1. My company website has several Google Ads landing pages from 2020, 2021, and 2022. What’s the best approach to handle these older pages?
2. There are also some old blog posts with very thin content. Should I update, consolidate, or remove them?

Any suggestions or best practices would be greatly appreciated!

Thanks in advance!
