Does 301 redirect of old filenames still work?

[optimind]

I have gone through several revisions of my site. We used to have only static pages in HTML. I had search-engine-optimization.html changed to seo-philippines.html changed to /seo-philippines/

I 301 redirected all of them whenever I change the filenames. This is in the course of 6 years worth of link building and I'm wondering if this has an effect because our rankings go down everytime we do this.

thanks. this is helpful. i did change twice since 2004 because of the redesign and more recently, the change in platform (changed to wordpress from static)

Yes Wendy, the frequent changes in the file names will definitely have an impact in the rankings. Though, you are using a SE friendly redirect, it is STILL a new URL for the SE to index. Everytime it finds a redirect, it takes some time to understand and pass on the value.

When the value is passed, when through a 301 redirect, there is some link juice lost. Also, when you redirect A To B and then B To C, make sure you also redirect A To C. Do not have dual redirection on the old filenames, change everything when there is a change in filename, including the link building also (old links and new acquired).

I would still suggest to refrain from doing frequent changes to file names!
