301 redirects are the redirects you want to be doing to keep the search engines happy. Understanding 301 redirects is an important part of preventing duplicate content and good SEO.
Alternative domains not in Google
A customer has just brought to my attention a problem that hadn't
occured to me. It's to do with all those other domain names you own
and are 301ing to the main site.
PROBLEM:
You have www.domainname.com and it's appearing in Google searches for
"www.domainname.com" like it should.
You have www.domain-name.com 301ing to www.domainname.com and it's
NOT showing in Google searches for...

PHP redirect function (301 / 302)
I'm often asked how to do 301 redirects in PHP. It's not hard, but
it's a pain having to remember the exact syntax every time. Here's a
little function I wrote for Jojo CMS for making redirects easy.
USAGE
Add one line of code whenever you need to do a redirect.
301 REDIRECTS...
redirect('http://www.domain.com'); or
redirect('http://www.domain.com', 301);
302 REDIRECTS...

That trailing slash DOES matter
I have been all bitter and twisted the past few weeks about Google
putting some of my pages into the supplemental index.
And not just my rubbish pages, some of my best content has gone
supplemental. After chewing on the problem for a couple of weeks, I
have it figured out.
It's the TRAILING...

Why don't people use 301 redirects?
I have just completely revamped the NZ Coastguard boating education
website tonight.
When I say "revamped", I mean make substantial changes to the backend
with virtually no changes to how it looks - if anyone notices anything
new, I'll be surprised. Clients aren't going to notice the new nice...

Ferrit SEO their site properly - sort of?
I have been in the process of writing a SEO article all about
www.ferrit.co.nz[1] - a multi million dollar website with more SEO and
web development mistakes than a drunk illiterate kid with Microsoft
Frontpage could make.
My article covered what you don't want your website to look like
after...

Duplicate Content
Duplicate content occurs when blocks of text are published on
different websites. An awareness of how duplicate content works in
Google should be an important part of your SEO strategy. This morning
I ran into a very interesting case of duplicate content on a site,
where SEO efforts were actually...

PHP 301 Redirects
The preferred way of redirecting a page that has moved is by a 301
redirect. In PHP, 301 redirects are not the default (a 302 redirect is
the default). Whenever you move a visitor to a new location, you
should use the PHP 301 redirect, which involves one extra line of
code.
In PHP, a 302...

Redirects - the good, the bad and the ugly
Redirects are an important part of a well maintained site. As pages
are deleted or moved, it's common courtesy to sent the visitor to the
new page, or at least apologise for the inconvenience.
TYPES OF REDIRECT
Redirects come in several flavours. Redirects can be done by the
server, or by the...

Preventing Duplicate Content
Duplicate content is a problem with many websites, and most webmasters
don't realise they are doing anything wrong.
Most search engines want to provide relevant results for their users,
it's how Google got successful. If the search engine was to return 5
identical pages on the same page of the...
