The links between accessibility and search marketing are frequently explored: creating a universally accessible website has a number of significant benefits for search marketing. After all, many of the features which make a website accessible (using text instead of images, ensuring the ability of non-visual tools to fully access content, etc.) are also characteristics of a website which has been optimized for search.
However, there’s a huge difference between search engine optimization and search engine friendly. What most accessible developers create are search engine friendly sites, not optimized sites.
Stoney de Geyter wrote on this issue from a search marketing perspective at Search Engine Guide today, commenting that:
A good developer can do that job well, but mostly they do it to function for the user, not perform for the search engines.
This is very true, and it absolutely describes the kind of development I focus on. I do have a pretty extensive knowledge of search engine optimization, and absolutely incorporate aspects of optimization when I develop a website. However, what I’m actually creating is a search friendly document.
5 Differences between Optimized and Friendly
1. An Optimized page has carefully researched and tested page titles and descriptions which perform well in search engines. A Friendly page has well-written unique page titles and descriptions which explain the page simply and accurately.
2. An Optimized page has content carefully written to incorporate key phrases which, on the basis of research, will help the site convert search visitors better. A Friendly page has content which has been carefully written to be clear and understandable to the widest possible range of people.
3. An Optimized page is designed to influence visitors to follow navigation paths which drive them to accomplish conversion tasks: sales, registrations, or sales queries. A Friendly page has made certain that all navigation paths are followable by a search engine to make certain that all important pages can be indexed.
4. An Optimized site is the product of months or years of research into what provides the best results for search visits and conversions combined. A Friendly site is the product of a development process which has taken all the technological issues which could reduce search relevance into consideration: robots.txt, correctly formatted redirects, etc.
5. An Optimized site is the result of extensive research. It requires a statistical basis which keeps track of user behavior. A Friendly site is the result of technical expertise which takes into careful consideration the many issues which can get in the way of optimization.
These are crucial distinguishing points. As an accessible web designer, I make a point to prepare a website which is search engine friendly. It is not part of the process to optimize the site, however. That is a separate, long-term task which, although it depends on “friendly” web construction, is ultimately based on statistics. Accessible or search-friendly design, while influenced by existing knowledge of what helps optimize a website, is based on criteria concerning the ability of users (or devices) to access the site.

Excellent article Joe. I’ve blurred the terms many times myself, but I guess after reading this, I don’t really “optimize” my sites, but rather just enhance or optimize that “friendliness” so as to get the biggest SEO bang from the buck from my standard production and use of accessible sites. I try to make my sites user-friendly and accessible — which is my first priority — and knowing certain things such as using good titles and headings, I guess I felt I was providing optimization as a result. In a way I have been of course, but not “optimizing” to the level you’re describing. Of course most of my knowledge in this realm is the result of happy accidents. In other words I did something for accessibility and/or usability, then later realized a nice side benefit.

Thanks, Mike. In some ways, it’s quibbling over terminology. But on the other hand, the word “optimize” is pretty strong language. It’s not really fair to call something “optimized” when you haven’t really done the work to make sure it’s really the case.
I thought it was an interesting point.

Yes very good article indeed.
It is very interesting and en lighting to read what you wrote and explained as I am sure most of us did not fully know the difference before, I know I did not.
I also agree that you should FIRST get the website friendly and then optimised.
Thanks again

I found this article very informative Joe. I was aware of the difference, but this clarified some points which I may have merged together. Top job!

Thanks, Armen! It makes sense to separate the two ideas — but figuring out exactly where to draw the line can be rather tricky…
Comment by Joe Dolson — May 17, 2007 @ 10:49 am
Whoops - and thanks, Jermayn, also!
Comment by Joe Dolson — May 17, 2007 @ 10:50 am
I just wanted to say thanks for this. I’m in the middle of a series of blog posts that offer a basic introduction to organic SEO, and the latest one is about the importance of clean code.
I wanted readers to understand that lean and semantic code is just part of the equation, but I didn’t want to bog down in details that I already planned to get to later. A link to this post did the trick nicely, and you’ve probably explained it better than I could.
Personally, I think of search engine friendliness as part of an overall optimization strategy. You can’t have one without the other, so pitting them “vs.” each other seems kind of odd. Aside from that minor quibble, this is a great piece of educational blogging!
Comment by Adam Messinger — May 18, 2007 @ 4:01 am
Thanks, Adam! I guess my thinking on the “vs.” question was about pitting the definitions against each other: taking apart the two terms and demonstrating where they differ.
Definitely do agree that putting the two activities against each other would be rather strange. I’ll try and avoid giving that impression again!

Excellent stuff Joe, and as an SEO, I’m glad to see an accessible web designer grasping the difference
Comment by Joost de Valk — June 9, 2007 @ 11:07 am
Thanks, Joost! I’ve done a fair amount of work in the search realm, as well - so it’s important for me to make the distinction.

Hehe cool, I’m the other way around

Do you think that it’s impossible to combine an optimised site and a friendly site in one?

Of course not — “friendly” is just the first step. They aren’t mutually exclusive; they just shouldn’t be conflated.
Comment by Joe Dolson — September 20, 2007 @ 10:03 am
So, as I understood from your post, my site is friendly, not optimized. But can we combine features of optimed and friendly website in one project?
