64,000 Pages Indexed on Google!??

I have been checking one of my blogs on Google (New Zealand) recently with a Site: search to see how many pages were indexed.

It was around 8000 pages and slowly growing each day.

Now when I do the same search I get the result "About 63,400 results"

I got someone in Australia to check and it came back with about 40,000 results for them.

The blog only has around 20,000 posts.

Is it normal to have more indexed pages than posts on a blog? All my other blogs have less indexed pages than posts.

I have noticed a definate spike in traffic recently too.

maybe your "tag" or "category" pages are also indexed.

If you have a translation option, it will index the page in all the languages it has been translated to. (atleast that is my experience)

Oh Yes, I just checked through some of the results pages and it does look like the tags have been indexed. I guess that explains it.
