How Users Read On The Web


In research on how people read websites we found that 79 percent of our test users always scanned any new page they came across; only 16 percent read word-by-word. We found that credibility is important for Web users, since it is unclear who is behind information on the Web and whether a page can be trusted. Credibility can be increased by high-quality graphics, good writing, and use of outbound hypertext links. Links to other sites show that the authors have done their homework and are not afraid to let readers visit other sites. Users detested "marketese"; the promotional writing style with boastful subjective claims ("hottest ever") that currently is prevalent on the Web. Web users are busy: they want to get the straight facts. Also, credibility suffers when users clearly see that the site exaggerates. To measure the effect of some of the content guidelines we had identified, we developed five different versions of the same website (same basic information; different wording; same site navigation).


We then had users perform the same tasks with the different sites. As shown in the table, measured usability was dramatically higher for the concise version (58% better) and for the scannable version (47% better). And when we combined three ideas for improved writing style into a single site, the result was truly stellar: 124% better usability. It was somewhat surprising to us that usability was improved by a good deal in the objective language version (27% better). We had expected that users would like this version better than the promotional site (as indeed they did), but we thought that the performance metrics would have been the same for both kinds of language. As it turned out, our four performance measures (time, errors, memory, and site structure) were also better for the objective version than for the promotional version. Our conjecture to explain this finding is that promotional language imposes a cognitive burden on users who have to spend resources on filtering out the hyperbole to get at the facts. When people read a paragraph that starts "Nebraska is filled with internationally recognized attractions," their first reaction is no, it's not, and this thought slows them down and distracts them from using the site.

This specification defines an API for storing data in databases that can be queried using a variant of SQL. Beware. This specification is no longer in active maintenance and the Web Applications Working Group does not intend to maintain it further. This section describes the status of this document at the time of its publication. Other documents may supersede this document. This document is the 18 November 2010 Working Group Note of Web SQL Database. Publication as a Working Group Note does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress. The W3C Web Applications Working Group is the W3C working group responsible for this document.


This document was on the W3C Recommendation track but specification work has stopped. The specification reached an impasse: all interested implementors have used the same SQL backend (Sqlite), but we need multiple independent implementations to proceed along a standardisation path. The Web Applications Working Group continues work on two other storage-related specifications: Web Storage and Indexed Database API. Implementors should be aware that this specification is not stable. Implementors who are not taking part in the discussions are likely to find the specification changing out from under them in incompatible ways. Vendors interested in implementing this specification should join the aforementioned mailing lists and take part in the discussions. All feedback is welcome. The latest stable version of the editor's draft of this specification is always available on the W3C CVS server. This specification is automatically generated from the corresponding section in the HTML5 specification's source document, as hosted in the WHATWG Subversion repository.


This document was produced by a group operating under the 5 February 2004 W3C Patent Policy. W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. First, a function prepareDatabase() is defined. This function returns a handle to the database, first creating the database if necessary. Sometimes, there might be an arbitrary number of variables to substitute in. All diagrams, examples, and notes in this specification are non-normative, as are all sections explicitly marked non-normative. Everything else in this specification is normative.The key words "MUST", "MUST NOT", "REQUIRED", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in the normative parts of this document are to be interpreted as described in RFC2119. For readability, these words do not appear in all uppercase letters in this specification. Requirements phrased in the imperative as part of algorithms (such as "strip any leading space characters" or "return false and abort these steps") are to be interpreted with the meaning of the key word ("must", "should", "may", etc) used in introducing the algorithm.Some conformance requirements are phrased as requirements on attributes, methods or objects.
