How do i know if my links are being classed as spammy?

[Dorzone]

I have recently notice that a lot of my domains are dropping positions where they have been in a solid position for nearly a year which was good
I am now wondering if google is dropping them due to spammy links but i don't have the first clue how i would find this out.

Does anyone have a good way to figure this out or anything to help with this?

Verify your website in https://www.google.com/webmasters/ (google webmaster tool).

If you have spammy, unnatural links they'll send you a warning, but they won't tell which ones are bad.

cheers thanks for that. i have already done that and i've heard nothing from google so it must be something else. its odd because i have been no.1 for a few search terms in google for a long time now and all of a sudded there all dropping.

Could you think of anything else this might be?

Did this happen after the 5th Nov? If this is the case it's most likely down to the new Panda refresh update that occurred on the 5th.

the could be a number of reasons why you've been hit. First I would focus on the page content. Is my page beneficial and useful for the user? Can it be improved?

This would more likely be due to Penguin from a linking point of view. If the drop is due to Panda timing it will likely be a content issue. 
IF you know you have links that are bad, use the disavow for the links and take them off. If you check your content and you have duped content or poor or thin content, it will need to be improved in order to gain ranking.

Remember these are algorithm changes/improvements and not penalties. It becomes more difficult with them and you must research to ascertain most likely cause.

What about the content? Low quality or high quality and informative?

[Dorzone]

I'm pretty sure that the content is high quality although it has been the same for a while now so maybe it needs updating?

Let me know what you think of the quality? http://www.dor2dor.com

I think that changing the content a bit could be the trick, keeping a site fresh is pretty important.  Do you feel you've done any link building that could be considered spammy?  Be honest with yourself on this one.  Otherwise, tweak your content a bit, give it some updates.  Update your sitemap and resubmit.
