Am I under google penalty and how to fix it

I have ranked for a serval KW on average #10 position and 1 KW to #3-1 .Suddenly the KW started to dissapear from the ranking for a few days and then come back stronger, I thought that is big dance before final push on top positions but since about a week all 8 KW varnished from the index and only 1 KW left on position 7.
The website is not removed from the G index, some inner pages can be found
No messages in GWT (maybe no manual action)

The website is kind of scraping and organasing content from different API, have also unique 500 words article on the page where I try to rank, not over optimised.
about 500k submited and 23k indexed in GWT
I'm guessing I have been hit by some algo update.
1: tiny content, I have ordered 2000 word content article to replace the old 500 word on the page.
2. I use small % diversity on the anchors. Here can be the problem but if anyone can help me I will appreceate that really. 10 KW with 10-50 exact pbn anchor each. pointing only 1 page, and about 100 other links with diversity

There's a huge update going on that started at the end of August and it's still strong today. What you're experiencing sounds like the update. Just give it time and carry on as usual with seo etc.

i would wait and if no recovery start a new one. its easier...

Ah thank you, after quick search I come to the topic for this eventual update http://searchengineland.com/big-google-search-update-happening-chatter-thinks-258142

Content is king

you need to add more content to your site
I would do 700+ words per article
if you can get some 1000+ words article it will be very good
after that I would go and make some backlinks to the website in order to index it back fast

So after I added more content and waited about week nothing happens. It get even worst . I lost 3 KW where I was ranking on page 2 now - nowhere. Saw in the forum another people have same issue.
There must be something that we don't know still.

And you know why? Because you listen to bullcrap that newbies post here. "Content is king", "add more content". Yes, sure, you just wasted money for no good reason at all.

Your anchor text ratio is over the roof. And you know what Penguin updates target, right? Anchors and backlinks, yay! Your exact keywords are on 10% pretty much, you have no diversity there whatsoever. Not to mention the thin content you have.

So either diverse your anchors and see if it comes up, but if I were you, I would forget that site and move somewhere else. Also, if it's a hack/crack site, which I believe it is, then forget it completely and forget ranking hack/crack sites as well. It's easy to rank them, but they don't stick around for too long. Not worth the money.

Google new algorithm updated in september, you have to consult some expert for recovery if you think your site got penalty.

^^^ Oh shut the fuck up with this bullshit already. Guy did a bad decision due to post hunting newbies already and to be honest, it's getting on my nerves. I'd be banning posts like this left and right if it were up to me. Newbies then come to forum, seeking advice and all they get is "Content is the king" bullshit or something completely off topic.

You know why 99% people fail in IM? Because they get stupid advice as soon as they get their feet wet.

Thanks for the replay!
No, my website is not for cracking/hacking . It is strange because 2 of my other top keywords droppped only a few positions, and one goes from position 18 to 90. So there is no major penalty but only those 3 KW with the highest search volume are gone.... I already put some diverse links, and will continue pumping more PBN for quality no 2.0 webs/profiles but with generic KW and brand names. I lost a lot of money for link building and I also earn some good money so I don't want to just move on.
Also I put new 2k words article just to be safe but I'm not planning to put more content as it looks strange on this type of websites :}
New main goal is to make anchor % under 10 but the question here is: is the other KW counted as generic to the each other? Lets say I have 5 KW
1KW 50 anchors
2kw 30 anchors
3kw 70 anchors
4kw 20 anchors
5kw 40 anchors

Total 160 exact anchors pointing to 1 page.
That means I have to put 1600 more generic links ? or 500 because 1 KW is 50 and the other 2,3,4,5 are KIND of generic ?

Some links, especially on PBNs are partially site wide, counted from multiple sources like category pages or tags. So check majestic or ahrefs and you will be wiser. Or install GWT and you will see where you stand.

I have GWT but that does not help me. You are right about the public pbns but that is my first serious seo project, I had small succes with micro niches before. Now when the game changes for real big KW things get messy. What should i looks for in ahrefs?

For your actual anchor ratio.
