Is it worth optimizing old videos?

Hey guys,

I have been creating a ton of videos for the past 2 years (around 200 now) all videos are well edited original good content.

Only recently have I started learning about the importance of SEO on Youtube and what is important to rank a video including proper Keyword research.

Is it worth it to go back and re-evalute/optimize old videos or is it too late for them? Can I still rank an old video?

Thanks
Mike

I asked the same question awhile back and the answer I got was yes, you should optimize all of them if they are public. Think if it as spreading as many eggs out as possible you cover more ground meaning you get more views which I may equal more subs.
Hope this helps

Yes I once a change a video title to a term people were searching for it started 800+ views a day. That video had been up for months under a different title

A significant re-optimization triggers a re-evaluation of the videos. That could be good or bad based on what you're doing to the videos and how it's performance is recently.
