Steve: Excellent comment, and I loved this line - "...whether they should be outsourcing it or not, they have too much geek in them to do otherwise."
I'm familiar with this issue because I'm a geek and I think you know that I'm totally comfortable with geeks doing geeky things because they're not in our taget audience. But on to your more serious comments... "As you can see from the comments at the Lab, I'm not the only one."
Yes, and it is the widespread interest in doing it themselves that was what I found so unexpected. I can totally relate to someone of your background doing this. "Is/was your company aware that the Wordpress admin function doesn't rewrite old URLs within the blog?"
Yes. "Hopefully you do now, and adding that to your scripts and making sure that gets done would definitely be value-added."
Yes, we do, and we go even further. When a company converts from say a Wordpress blog to Blogsite we also transform all historical content to the new domain (if indeed that's the case), and/or to the new URI's. Most blog tools (as you know) do not truly embrace the idea of unique URI's; MyST Blogsite does, and in the process of integrating legacy posts, we provide each with a bona-fide GUID and corresponding URI that becomes the authoritative home for the object. We also handle the creation of permanent redirects from the legacy URL's for all posts to the new home for each object. "I don't see your company doing, is going to all of the various social networking sites (and quite probably google & yahoo) to re-register the blog."
Correct, we don't manage all the social site changes because it's generally impractical to do so (security and credentials being the biggest show stopper). However, some business people do want this task outsourced. With regard to search engines - yes, we manage all of that for new and existing clients that are changing domains, brands, names, etc. We even re-register all feeds across 80 RSS search engines, and of course, the new feeds contain all the new URL's. |
