In firs month all content in my website were copy of original content (duplicate content) and end of content link to original content.
after that I solve duplicate content and hard work on link building but number of clicks In google.com/webmaster not increase.
google penalty mywebsit?
how to detect mywebsit be penalized?

[Chedders]

And what link building have you been doing ?
If they are on spammy sites then that would effect yours and the trust has gone.

If you have not seen a penalty issued in search console then no you wont have a penalty, you are now just ranking in the positions your site deserves after all the spammy backlinks.
Guessing here but I suspect that might be the reason.

messages in manual actions (in search console) is "No manual webspam actions found."
exist a reliable method that detect my website be penalized?

[Chedders]

Then your not penalized.

So what backlining have you been doing.
Your trying to shift the blame to google where I suspect its work you have done. I could be wrong of course but I bet the drop matches your building plan.

As i made a small research, your website possibly is not penalized. Keep in mind that last months there were some updates on google algorithm and a lot of people were complaining.
I also had a similar incident and my issue was that my ranking dropped from #3 to #9 for a specific SERP.
To make the long story short, check your link velocity, your backlink technique pattern and of course to realize your droppings find out your positions on SERP before and now.

[Chedders]

THis is difficult as the site is not aimed at english speakers, just trying to check the site is difficult for me so I am going to echo my comment about check your backlink profile. I am fairly sure thats where the problem lies.

[amahdavi]

I think google penalty mywebsite for duplicate content because:

1.In firs month, all content in mywebsite were duplicate content and i not remove this content of mywebsite.
2.for content in first month: assume, title of page "mywebsite/123" is "duplicate content - mywebsite" and content of this page copy of original content. original content exist in main site "mainsite/444". title of original content is "mainsite | duplicate content".
when i search query "site:mywebsite-com", google show title "mainsite | duplicate content" Instead of "duplicate content - mywebsite".(link is to URL "mywebsite/123" but title is from URL "mainsite/444")

but for content that exist on other month in mywebsite (solve duplicate content) i have not this problem.

possible google penalty me for this reason?

If you have duplicate content then obviously you should solve that. You can read more about some solutions here: https://support.google.com/webmaster...er/66359?hl=en

As Chedders suggested, taking a look at your backlinks will probably help as well.

I also believe that someone said you probably aren't actually penalized. If that's true, it's more likely that you just have a very low quality website. In which case, it might have done well initially because it was "fresh," but now your clicks and rankings might be falling because that freshness is fading.

[amahdavi]

my website is a news site and show new daily news of my country (language is persian and news is not international).
markroberts: it might have done well initially because it was "fresh," but now your clicks and rankings might be falling because that freshness is fading.
No, because in first month and other month, the contents of my site were daily news.(quality of contents not different in several month )
