Question
I need to remove 6,000+ URLs from a website which has already been crawled by Google.
What will be the best way to update those URLs? By updating those URLs to 404, noindex no follow and canonical or other?
Please suggest me what will be best from an SEO point of view.
Answer
This completely depends on your goals...
Want to retain link juice? 301 redirect.
Want to get rid of poisonous results? Just 404 them today.
Are they all the same exact page? Canonicals
