Passive Voice Is Redeemed For Web Headings

When passive voice is best ...

Active voice is best for most Web content, but using passive voice can let you front-load important keywords in headings, blurbs, and lead sentences. This enhances scannability and thus SEO effectiveness.

Traditional writing guidelines are clear on the use of passive voice:

* Worst: The passive voice should be avoided.
* Bad: The passive voice should be avoided by writers.
* Better: Writers should avoid using passive voice.
* Best: Writers should use active voice.

When structuring a sentence, active voice ("Actor does X to Object") is usually better than passive voice ("Object has X done to it by Actor") because it more directly represents the action. As a result, readers don't have to jump through as many cognitive hoops when trying to understand what's going on.

For the same reason, it's usually better to write a positive statement ("do X") than a negative statement ("avoid Y"), and it's almost always horrible to use double negatives ("avoid not doing X"). Again, the simpler the translation between the text and the user's mental model, the easier the writing is to understand.

Typically, it's even harder for readers to understand passive sentences that don't explicitly state the actor. This style can also lead to additional usability problems if users misinterpret who's doing the action. For example, if you write "Social security taxes must be paid monthly" readers might think that employees have to pay the tax. In contrast, "Employers must pay social security taxes monthly" is clear and easy to read.

* Usability increases when users need fewer mental transformations to convert a sentence into actionable understanding.

Writing style impacts website profitability: the easier the writing is to understand, the more likely customers are to plow through your words. Users don't like doing hard work. That is, users prefer effortless reading (to state it positively, and thus improve readability).
When Passive Voice = $$$
Here's the first draft of my summary for a recent Alertbox column, entitled "Tabs, Used Right":

Yahoo Finance follows all 13 design guidelines for tab controls, but usability suffers due to AJAX overkill and difficult customization.

Active voice, yes sir.

Fairly well written, check.

Complete sentence, not a fragment; no disapproving squiggles in Word.

All systems go, except for one nagging question: Does this blurb perform its main job — to attract users who scan SERP listings (search engine results pages) or other lists of possible destinations? No. It fails this mission horribly.

Don't pass Go, don't collect $200.

Users scan Web content in an F-pattern, and often read only the first 2 words of a paragraph. What are the first two words of my draft deck? "Yahoo Finance" — which has zero information scent for article's target audience.

The column in question is about application design, so it needs to attract readers who care about GUI widgets. People who are interested in Yahoo or investments are not the targets.

(I used Yahoo Finance purely as an example in the column; I don't actually discuss the site. I have written about Yahoo as a portal and about investor relations. However, those articles are at other URLs; users attracted by the misleading information scent created by leading with "Yahoo Finance" wouldn't find them.)

Here's the rewritten summary, using passive voice to pull the payoff keywords to the front:

13 design guidelines for tab controls are all followed by Yahoo Finance, but usability suffers due to AJAX overkill and difficult customization.

Because "13" is sufficiently short, users will likely fixate on the first 3 words, not just the first 2, when they initially scan the blurb. Also, numerals beat words when referring to specifics, so starting with "13" is even better at attracting the scanning eye."    (Continued via
