Newly Indexed Posts Aren't Ranking as Well As Aged Posts. Why?

[micho24]

I m extremely curious. I have a website which had about 62 pages, I didnt uploaded any new article for maybe half a year. (age of domain: 2 years). In last two months I decided to put a new batch of articles (exactly the same topic as previous 62) to the site. I added almost 30 new articles for stupidly low competition keywords. Maybe 2 articles from 30 rank for them (on page 1), all others are N/A (all of them are indexed, mobile friendly etc). All previous, already posted articles (62) in half a year ago are still ranking in TOP 5.

Articles quality: We rewrote the #1 spot but also added something new, article is 100% unique and written by native writer.

One thing I noted is coverage in webmaster tools:
Desktop coverage from 62 -> 95 valid pages, 0 errors,
Mobile usability from 60 ->62, 0 errors

Why all previous posted articles are ranking somewhere but these new are not? Any suggestions?

Thank you

Could be a few things:

1) you misjudged the competition
2) your domain is weak
3) Google could require posts in your niche to age longer before it rewards them, even low competition ones
4) they aren't SEO optimized

Give it time. Unless your domain is strong or your topics are truly super low comp, it takes a few months to rank organically.

Google has become much slower in indexing new content on "weak" domains. People used to think this was some kind of "indexation bug", but Google claims there's no bug.

So if you're not seeing traction, you should think about how you're interlinking your content, and if your content is quality and if you have enough trust. If you keep publishing, promoting and interlinking content, then Google will put your site into good standing again.

For the indexation, I noticed that if I posted the articles on facebook, twitter and mixer, it took 4 days tops (for now) to get them indexed. Tweeting at a big personality in your niche seems to speed this up, in my limited experience.
All of @bernard points seem to be spot on...
@shaunm has been mentioning this bug, but I haven't noticed it. So maybe we are missing something.
