Technical SEO

Traditionally, the phrase Technical SEO refers to optimizing your site for crawling and indexing, but can also include any technical process meant to improve search visibility.

Technical SEO is a broad and exciting field, covering everything from sitemaps, meta tags, JavaScript indexing, linking, keyword research, and more.

Are There Any Good Solutions for Caching Redirects?

Technical SEO

A couple of large client projects we are working on at the moment have had me thinking about a tricky issue that rears its head in enterprise SEO projects especially. When large clients are making extensive website changes, our experience is that the section entitled '301 redirects' is inevitably the section that gets read quickly and then quietly shuffled out of scope. We have found we have to push hard to get large businesses to see the importance of permanent redirects.

How Do You Register for Google Local with Multiple Languages?

Technical SEO

There are some difficulties at the moment with how to manage large numbers of local listings. As the tools for managing local listings improve, this will all get easier, but there is a fundamental problem with the setup if you operate in multiple languages. The guidelines currently say that you cannot create multiple listings for an individual entity (business location in a city) - but each listing is just associated with a single URL which doesn't work well when you operate in multiple languages.

Canonical URL Tag - The Most Important Advancement in SEO Practices Since Sitemaps

Technical SEO

The announcement from Yahoo!, Live & Google that they will be supporting a new "canonical url tag" to help webmasters and site owners eliminate self-created duplicate content in the index is, in my opinion, the biggest change to SEO best practices since the emergence of Sitemaps. It's rare that we cover search engine announcements or "news items" here on SEOmoz, as this blog is devoted more towards tactics than breaking headlines, but this certainly demands attention and requires quick education.

Do Sitemaps Affect Crawlers?

Technical SEO

Like any other person out there, I fall into habits, good and bad. Recently while working on a client’s website, I created a Sitemap and submitted it to the search engines, like I always do. I started to think if this really helps the site out and what’s the effect when I submit a Sitemap on the site.

What Quantum of Solace Can Tell Us About Information Architecture

Technical SEO

I've said it before, and no doubt I'll say it again: in my opinion, the number one reason for websites failing online is because they have a poor information architecture. Don't worry, I'm not going to compare myself to Bond. Instead, I'm going to use Quantum of Solace to demonstrate how something as simple as categorizing a new action movie can lead to some serious problems in your site architecture. (Just for the record, I tend to use the phrases 'site' or 'information architecture' interchangeably to cover a multitude of sins.)

Why New Content Briefly Flickers Out Of Google

Technical SEO

A few days after new content shows up in Google, it will sometimes flicker out of the SERPS for a few hours. Apparently, this is common knowledge to some SEOs. This is not common knowledge to programmers like me, and I nearly made a tin foil hat in preparation for the googlicopters when I learned the project (Linkscape) that I'd worked on for months had disappeared from all SERPs on th...

XML Sitemaps: Guidelines on Their Use

Over the past couple of days I have been putting together some internal guidelines on various aspects of our jobs. This should ensure that we are giving consistent information to our various clients. Most of these guidelines have been fairly straightforward with nothing in them to write home about. However, one of the hardest guidelines to write has been the one talking about xml sitemaps. ...

An SEOmoz PRO Tip (For Everyone) & Feedback About the PRO UI

Technical SEO

Lots and lots of people sign up for SEOmoz's PRO membership, and I have to tell you that on a personal level, every single one makes me feel honored, humble and yes, even a bit guilty about reading comic books last night instead of working on new tools/q+a/tips/etc. One of the big frustrations PRO members have, though, is that they can't find (or don't even know about) a lot of the cool st...
