Editing Findability (section)

==Evaluation and measures==
'''Baseline findability''' is the existing findability before changes are made in order to improve it. This is measured by participants who represent the customer base of the website, who try to locate a sample set of items using the existing navigation of the website.<ref>{{Cite book|title = Customer Analytics For Dummies|last = Sauro|first = Jeff|date = 2 February 2015|publisher = John Wiley & Sons|isbn = 978-1-118-93759-4|url = http://www.wiley.com/WileyCDA/WileyTitle/productCd-1118937597.html}}</ref><ref>{{Cite web|url = http://www.measuringu.com/blog/measure-findability.php|title = How to Measure Findability}}</ref>

In order to evaluate how easily information can be found by searching a site using a search engine or information retrieval system, [[retrievability]] measures were developed, and similarly, navigability measures now measure ease of information access through browsing a site (e.g. [[PageRank]], MNav, InfoScent (see [[Information foraging]]), etc.).

Findability also can be evaluated via the following techniques:
* [[Usability testing]]: Conducted to find out how and why users navigate through a website to accomplish tasks.
* [[Tree testing]]: An [[information architecture]] based technique, to determine if critical information can be found on the website.
* [[Card sorting|Closed card sorting]]: A usability technique based on information architecture, for evaluating the strength of categories.
* [[Click testing]]: Accounts for the implicit data collected through clicks on the user interface.<ref>{{Cite web|url = http://www.nngroup.com/articles/navigation-ia-tests/|title = Low Findability and Discoverability: Four Testing Methods to Identify the Causes|date = July 6, 2014}}</ref>
