In commercial ranking, factors that evaluate user activity on the site play a large role. These are mouse movements, screen scrolling, clicks on buttons, links, filling out forms, etc. The more active these actions are, the better the usability, i.e. the convenience of using the site. If the site is inconvenient, then the visitor's activity is low.
Therefore, a commercial site needs to have convenient tools for interacting with the visitor. An online store needs a shopping cart, an order form with logical fields, prompts that can be easily and quickly filled in, and an online payment system.

If the price of a product or service is not fixed, but depends on various factors (weight, material, etc.), then you will need to place a pricing calculator, with the help of which the user can independently calculate the price and select the desired option.
The wider the range, the more difficult it is to find the desired product in the catalog. Moreover, many products can be classified as peripheral. For example, a person can search for a smartphone case in the "Accessories" section, but it is in the "Phones" category. In this case, searching for products on the site itself will make the task easier, as well as the option to compare products by key parameters. All this helps to keep a potential buyer on your site and improves ranking.

User support
To ensure high-level service, you can organize support in the form of online consultations using special services or Internet messengers (ICQ, Skype). Another convenient way is the "Callback" service. The user leaves his number, which the operator calls him back at a convenient time. At the same time, support should not be annoyingly intrusive. Windows should not pop up in the middle of the monitor, otherwise they will resemble advertising. If it is not possible to organize online support, then you need to provide a feedback form. The main thing is to respond to incoming letters as quickly as possible.
Groups in social networks
For search engines, a company's activity in popular social networks is a plus. To demonstrate it, you can place widgets of groups and communities on the site, which are led by company representatives.
Absence of advertising
The presence of third-party advertising on the site can negatively affect the ranking, especially if aggressive formats such as pop-under or click-under are used.
Design quality
The design shouldn't be too simple. The worst solution is a standard free template that is used for sites created for monetization by displaying contextual advertising (Made For Adsense) or selling links (Made For Sape).
Technical parameters
Yandex employees give examples of some commercial factors that relate to technical parameters:
- domain name readability,
- average page title length,
- page title correspondence to its content,
- average URL length,
- average URL nesting depth. The average URL length, title tag, and page nesting should be minimal in length.
