Any and all help would be much appreciated -- this is a BIG next step for
me, TWO years after my initial launch, and is finally going to mean my
shifting from a heavily-hacked 1.0a codebase to a (hopefully) mostly
plugin-driven 1.5.x site.  And I can 'reclaim' chait.net for my
coding/consulting work!  Yay! ;)

Thanks all!

Hi David,

This was probably intended to be a parent node (post) rather than a
reply to
Amit, but regardless:

Use 301 re-directs as described below:


You can make all posts/items in your old site send the appropriate HTTP
and 'throw' their PageRank at the new site. Use Apache's mod_rewrite if you
want to re-direct users to corresponding pages in the new Web site.

Reply to list if you prefer, but I /suspect/ it might be frowned upon by

People on the list frowning on postings? Never! ;)

Okay, let's try...

Actually, I'd think this a good topic given the growing number of 'inadequate hosts', and that many folks start with free accounts then want to migrate elsewhere. But I'll just cobble it all together and make a posting myself, so people can find it. :)

People ask these sorts of questions all the time (especially in the SEO
newsgroups) and the answer is almost the same:

-Use redirects if permitted

-If not, learn the lesson and never start a site on somebody else's turf.

You can never predict future growth. Even proper redirects typically incur the
loss of deep inbound links. On top of that, put broken bookmark links, not to
mention the loss of identity, the endless work on migration (think of sites
with >100,000 pages) and PageRank that is often leaked in the process.

Yeah, I understand the (rudimentary) 301 stuff -- as that's what I send back to referrer spammers in CG-Referrer, hoping that I'll catch a few of them in their own trap. In PHP there's certainly pretty much an open book as to what I can do, but I 'suck' at htaccess/mod_rewrite rules (admittedly!) and I think that is the 'faster' redirect option for the most part. I mean, I've got less than a dozen articles I will likely keep on chait.net, so that's probably one rule with a regex that hard-matches <12 "?p=ZZZ" post IDs.

It's more fundamental than Web developer will have you believe. To
~/public_html/.htaccess, add the following:

RedirectMatch permanent ^/articles/page1 http://chaitgear.com/articles/page1


RedirectMatch permanent ^/index.php?p=11 http://chaitgear.com/index.php?p=11

If your site is sufficiently small, there is no need for anything too

But the trickiness of the mod_rewrites (and where I go bonkers) is the complexity of the regex and the inclusion of not just a 301 redirect, but a 301 redirect to the NEW nice-URI format. Now that I think about it.. hmmm.

I notice that Dougal has just informed you of similar migration, from which you
can happily re-use.

Will Google, et.al., follow TWO 301 redirects safely? i.e., I do a master htaccess redirect on chait.net to either chait.net/wp/?p= or chaitgear.com/?p= (or whatever), BUT then on both I install one of the "single URL only" plugins, which will do ANOTHER redirect, from the p= format to the /archive/some-post-name format (which needs to be php, as it has to look in the DB, or at the least in a local text file -- a good optimization! -- for the proper post slug...).

I can vaguely recall something about Google disliking being bounced from place
to place. I think too many re-directions could get you penalised or simply
'nofollowed'. Dodgy sites tend(ed) to re-direct excessively.

Did that make sense? You know any good resources to 'dummies guide to mod_rewrite'? (All the master docs I've found got too complex too quickly, and I need a really simple case or two here, it seems...)

Or, maybe I just do it ALL in php, one shot, and be done with it... :) :)

Google has 871 pages of your site in cache. I think it's somewhat manageable for
per-item redirection. Parsing the .htaccess file would not be terrible either...
about 20KB? Temporarily at least.
