SEO and Usability

At first glance, search engine optimization (SEO) and usability seem to be quite distinct topics:

  • SEO is about attracting people to your site in the first place by making sure it shows up in search queries.
  • Usability is about people’s behavior after they arrive on your site, with the main goal being to increase the conversion rate.

Basically, SEO happens before the first click, and usability takes over from there. Both need to be good for a website to succeed. Having great SEO but lousy usability means that you’ll get lots of traffic, but the visitors won’t turn into customers. Conversely, a site with great usability but lousy SEO simply won’t get many visitors, so it doesn’t really matter how good it is.

Although they focus on different phases of the lead-generation funnel, there are many ways in which SEO and usability support each other and a few ways in which they conflict .

Dear Tumblr staff

Would you please stop changing the UI and make actual useful changes to the site?

Things that increase my usability and navigation?

  • Sent messages folder
  • Rebloggable responses to asks
  • Ability to block anon abusers via IP address
  • Ability to reveal anon abusers via IP address
  • Return ability to reply to fanmail
  • Reliable messaging system
  • Ability to filter users by groups

The site looks fine as it is, stop messing around with the interface and work on the usability.


A Tumblr user who would like the site to be usable not just have pretty icons.





I’ve finally fell in love with Kindle.

It’s amazing, to buy books in one click and immediately get them with no postal delays. Amazing to read even the thickest and heaviest books with device less than 200 grams weight. Amazing — to touch any unfamiliar word and instantly get a definition, or to highlight sentences without fear to sully paper. And, of course, every book being opened, opens just on page you’ve closed it last time. Oh, thank you, The 21st Century.

1911: Frederick Taylor publishes Principles of Scientific Management which describes time and motion studies and methods for improving industrial efficiency.

1957: The Human Factors Society is formed.

1967: Micheal Scriven writes about formative and summative evaluations in the education literature as applied to student learning and assessment. These terms would later be applied to different types of usability evaluations.

1979: Permanent Labs at companies like IBM perform what we now would call Summative usability testing. The first scientific publication with usability in its title appears, The Commercial Impact of Usability in Interactive Systems by John Bennett.

1980: Ericson and Simon publish “Verbal Reports as Data” which focuses on using the Think Aloud Method that would later come to dominate usability tests.

Alphonse Chapanis’ student, Jeff Kelley, is credited with coining the term “Oz Paradigm” which we now refer to as the “Wizard of Oz” method.

1981: Alphonse Chapanis and colleagues publish Tutorials for the First-Time Computer User which describes usability as more of a formative than summative activity. They suggested that observing about five to six users using the software will reveal most of the problems in a usability test.

1982: Wanting a more precise estimate of a sample size than 5-6, Jim Lewis published the first paper describing how the binomial distribution can be used to model the sample size needed to find usability problems. It is based on the probability of discovering a problem with probability ‘p’ for a given set of tasks and user population given a sample size 'n’.

Clayton Lewis publishes an IBM technical report using Herb Simon’s Thinking Aloud" Method in Cognitive Interface Design.

1983: The Psychology of Human Computer Interaction is published by researchers at Carnegie Mell on and Xerox PARC (Stuart Card, Thomas Moran & Allen Newell). This seminal book explains GOMS and Keystroke Level Modeling based on the earlier work of Taylor, Fitts and Gilbreth.

The first CHI Conference was held in Boston as part of ACM’s SIGCHI subgroup.

1984: Apple introduces the Macintosh during the 1984 Super Bowl, making the case that ease of use sells.

Smith and Moser publish 997 guidelines for Designing User Interface Software.

The Human Factor, by Harry Hersh and Dick Rubinstein, both at Digital Equipment Corporation, is published. It is the first book-length description of human-computer interaction.

1985: J. Gould and Clayton Lewis publish the influential paper, “Designing for Usability: Key Principles and What Designers Think”. They discuss an early and continual focus on users as well as empirical measurement and iterative design.

Computer Usability Testing & Evaluation by Richard Spencer is published.

1986: John Brooke at Digital Equipment Corporation creates a “quick and dirty” questionnaire to assess the usability of software. The System Usability Scale (SUS) has gone on to become the mostly widely used questionnaire for evaluation perceptions of system usability.

The first local chapter of SIGCHI is started in Boston a few months after the annual SIGCHI conference is held there.

1987: Designing the User Interface (1st edition) by Ben Shneiderman is published. It is now in its fifth edition.

The Questionnaire For User Interaction Satisfaction (QUIS) is published based on the work at Ben Shneiderman’s HCI lab at the University of Maryland.

1988: John Whiteside at Digital Equipment Corporation and John Bennett at IBM published a number of chapters and papers on the topic of “usability engineering” (Whiteside, Bennett, & Holtzblatt,1988) which stressed early goal setting, prototyping and iterative evaluation. Joe Dumas, one of the godfathers of usability, attributes these papers and this period as the birth of usability as a profession.

Don Norman publishes the “Psychology of Everyday Things”, which later would be renamed the Design of Everyday Things.

1989: The Technology Acceptance Model (TAM), including a questionnaire to measure perceived usefulness and usability, is published by Fred Davis.

1990: Shackel publishes Human Factors and Usability which defined usability as a function of efficiency, effectiveness & satisfaction (the ISO 9241 pt 11 standard). Despite many proposed extensions, we still think of usability in terms of these three aspects.

Peter Polson & Clayton Lewis publish several papers on the Cognitive Walkthrough.

Jakob Nielsen & Rolf Molich publish the seminal paper “Heuristic Evaluation of User Interfaces,” in which they describe this influential discount usability method.

1992: Robert Virzi’s paper “Refining the test phase of usability evaluation: How Many Subjects is Enough?” is published. This, along with his previous paper found that additional subjects are less and less likely to reveal new information in a usability test. The first 4-5 users find ~80% of problems in a usability test (avg. p of .32). Severe problems are more likely to be detected by the first few users.

Jim Lewis publishes the Post Study System Usability Questionnaire (PSSUQ).

Website usability

If I have to scroll right to see your content, it simply will not be seen.

Mac mouse wheels are faulty. It’s a known problem so I have a pc mouse, allowing me effortless vertical scroll. It’s win.

The vertical scrolling action does not correspond with horizontal layout scrolling. A.

B. Spinning left and right on a screen has a tendency of giving people headaches.

Let’s leave horizontal content to the books, okay?
