If the p pages were only there for a small amount of time, then just forget them, as they wont have any links pointing to them.

don't worry about the SERPS they will go way soon.

but I would have renamed the HOME folder to a keyword. so that you get a keyword into your url.

automobiles.com/toyota/camery

is a better url than

automobiles.com/camery

I agree, never redirect when you can fix the link.

I am afraid that nothing you have said changes my mind, while you have an opinion, I am going by the hundreds of crawls I have made on WordPress sites and the thousands of problems I found on them.

No offence but only someone that can not write code would say tat WordPress could compete with a hand coded site.

Honestly, I find wordpress to be a nightmare for SEO, if you crawl a wordpress site they are inherently bad, themes make things worse and the more plugins the more problems.

I don't know a CMS that is perfect for SEO, but I think wordpress is the worst.

Thanks Paul

I had a look at the page, but as I can see it uses headers to identify the response, but the actions are rewrite or redirect. There is a custom response you can use,

for a definitive answer I would ask on iis.net http://forums.iis.net/

Or you could place each pdf in its own folder and place the header on the folder

Thanks for finding that, I see it says url, but I cant see how that is actually done. All it does it create a web.config in the folder you choose, I found no way of doing it ofr the indervidual file, unless you have only one file per forder

here is the web.config, how to test it works?

<configuration><system.webserver><httpprotocol><customheaders><add name="CononicalUrl" value="Link: http:/domain.com/my.pdf; rel=canonical"></add></customheaders></httpprotocol></system.webserver></configuration>

I don't think this can be done in web.config. I don't think it can be done at all.

while you can add a canonical header, to a folder using IIS, you cant add if to a file.

He's on a windows server and there is no .htaccess, you use web.config.

As I said before, if you are changing just the domain, then you can do the whole site in one redirect, but if you have a different page structure and thousands of pages, it would be a waste of time to do any pages that does not have a external link.

In this very rare case, they would get a 404, with a link to the home page.

to 301 every page in case it has a bookmark is a waste of effort
