Article pages yo-yo, while Tag Pages are constant

[vandread]

I'm experiencing a strange thing lately on my Wordpress blog. Whenever I write a new article I usually rank fairly well for it in Google. Usually in the top 50 even for very competitive terms.

The article disappears after a while from the search engines but the tag page will show up and rank fairly well for the search term.

Every now and then the article will come up again and rank for the search term again. The tag page remains on the position though.

I have never experienced this in the past and would like to know if there is a way to stabilize the article in the search engine.

I think you've got a challenge because of the way blog articles are ranked. They tend to get only short term power in the search results, unless they attract a huge buzz with lots of backlinks.
