Pageviews Reduced from 5k+ To less than 1k daily

Has this been recent? Here is an idea:

Check your stats for your keywords and how many searches you had on them for the last month you were doing well. Divide that by half for 15 days.

Now check your stats for November 1 through 15. Check against the two lists and see what keywords are dipping in visitors. Those articles have probably dropped in rankings or you quite advertising them or tweeting about them, etc.

You may need to write a few more articles on those keywords (but don't keyword stuff) and then interlink them together or point to the one article that was high in visitors but dropped.

If you are a person who backlinks, you may need to use onlywire to get some social bookmarks to the pages that dropped, or make a few blog comments (commentluv, keywordluv) pointing to those particular pages (vary keywords) and give that three weeks to start moving things up the ranks again.

Google update at any time can affect your website. but in most cases there may be something you've done wrong.

may you've done some unusual activity with your website, like: backlink frequency change, duplicate content (may be someone copied your content)

I think it is possible due to the re-design. I have seen some sites on Flippa with verified traffic and stats. After they were sold and were re-designed by the new owners, the traffic took a nosedive. Granted, I cannot be sure it is due to the change in design, but I think it is a possibility.

Maybe some people with experience will want to chime in.

You have poor internal linking which is screwing your PA distribution. I think some pages take 4-5 clicks to get to. Was looking at a post from April. PA of 1. Can't be right? Think that usually means that the PA from your homepage isn't being distributed to it very cleanly. Correct me if this is wrong.

Check on Webmaster tools / Screaming Frog to check your internal links. You can add "all time popular posts" as a short term fix or the slightly shit sub-category sitemap (home -> sub-category -> sub-category sitemap).

ALLEGEDLY, you need to implement a content silo. I'll be honest, I don't think I get what a content silo is. I think it's basically like a category tiered website (again aiming for a max of 3 links from the top) but with very little sideways linking between categories but a lot of internal linking within categories to keep your links relevant. This also means a lot of contextual links within articles to reference your old stories. I guess you're using some sort of keyword research for your articles?

Hit me back if you figure this out, I'll owe ya one.
