meta keywords: debatable, highly likely that it's not needed but I put it in anyway
meta description: yes, used as your serp snippet sometimes and the desc in Google+
content-type: yes, you're supposed to put it in there for html validation
robots (nofollow, noarchive etc): yes, if you want to do those things with your page
everything else: forget about it
Similar to what I found when I developed my first webpage (mine was a .com domain). Although mine got indexed adding the meta boosted the side a lot..Here is a test I made few weeks ago on blogspot.
3 blogspots made. One with no meta, one with meta and one on which I added meta after 2 weeks.
The one with no meta = no index even after 3 posts and 2 weeks past.
The one that had meta from the begining got indexed and ranked in top 100 on a small niche, in about 5-7days.
The one with meta added after 2 weeks, got ranked in top 100 after 2 days from the day I added meta.
No backlinks were made on them.
Hope it helps.![]()
Are meta tags important? Why or why not?
