Findability is the ease with qui information was contained website can be found, both, from outside the website (using search engines and the like) and by users already on the website.  Although it has become irrelevant to the World Wide Web , it is usually used in that context. Most relevant websites do not come up to the top results because designers and engineers do not cater to the ranking algorithms work currently.  Its importance can be determined from the first law of e-commerce , which states “If the user can not find the product, the user can not buy the product.”  As of December 2014, out of 10.3 billion monthlyGoogle searches by Internet users in the United States , an estimated 78% are made to research products and services online. 
Findability encompasses aspects of information architecture , user interface design , accessibility and search engine optimization (SEO), among others.
Findability is similar to, but different from, discoverability , which is defined as the ability of something, especially a piece of content or information, to be found. It is different from web search le fait que le word find Refers to locating something in a Known space while ‘search’ is in an unknown space or not in an expected rental. 
Mark Baker, the author of Every Page is Page One ,  mentions that findability “is a content problem, not a search problem”.  Even when the right is present, users often find themselves deep within the content of a website. He further adds that findability is intractable, perfect findability is unattainable, but we need to focus on reducing the effort to find a user.
Findability can be found on the market and on the market.
Heather Lutze is thought to have created the term in the early 2000s.  The popularization of the term findability for the Web is usually credited to Peter Morville . [ citation needed ] In 2005 he defined it as: “the ability of users to identify an appropriate Web site and navigate the pages of the site to discover and retrieve relevant information resources” Recalling to the web and information retrieval by Alkis Papadopoullos in a 2005 article entitled “Findability”.  
Is the domain of Internet marketing and search engine optimization (SEO) tactics. External findability can be very influential for businesses. Smaller companies may have trouble influencing external findability, due to being less aware to consumers. Other means are taken to make sure that they are found in search results. 
Several factors affect external findability: 
- Search engine indexing : As the first step, search engine indexing is shown in the search results. It would be useful to avoid being overlooked by indexing crawlers. These factors may include elements that require user interaction, such as entering log-in credentials. Algorithms for indexing vary by the search engine which means the number of webpages of a website being successfully indexed by Google and Yahoo! ‘S search engines. Also, in countries like China , government policies could significantly influence the indexing algorithms. In this case, local knowledge about laws and policies could be valuable. 
- Page descriptions in search results : Once the webpages are successfully indexed by web crawlers and show in the search results with decent ranking, the next step is to attract customers to the web pages. However, the customers can not see the whole web pages at this point; they can only see an excerpt of the webpage’s content and metadata. Therefore, in the search for information in a limited space, usually a couple of sentences, in search results is important for you and your webpage.
- Keyword matching : At a semantic level, terminology used by the searcher and the content producer be different. Bridging the gap between the terms and the use of customers.
On-site findability is concerned with the ability of a potential customer to find what they are looking for within a specific site. More than 90 percent of customers compared to browsing. Of those, only 50 percent find what they are looking for.  Improving the quality of on-site searches greatly improves the business of the website. Several factors affect findability on a website:
- Site search : If searchers within a site do not find what they are looking for, they tend to leave rather than browse through the website. Users who had successful site searches are twice as likely to ultimately convert. 
- Related links and products : User experience can be enhanced by trying to understand the needs of the customer.
- Site design, content creation, and recommendations are major factors for the customer experience.
Evaluation and measures
Baseline findability is the existing findability before changes made to order to improve it. This is measured by participants who represent the customer base of the website, who tries to locate a sample of items using the existing navigation of the website.  
In order to evaluate-how Easily information can be found by searching a website 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 (eg 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
- Tree testing : An information based architecture technique, to determine if critical information can be found on the website.
- Closed card sorting : A technical usability based on information architecture, for evaluating the strength of categories.
- Click testing : Accounts for the implicit data collected through clicks on the user interface. 
Findability Science defines a findability index of each user’s influence, context, and feelings. For seamless search, current websites focus on a combination of structured hypertext-based information architectures and rich Internet application-enabled visualization techniques.
