Installing and configuring a tag for AJAX and Flash sites

Tip. Working with the JavaScript API requires knowledge of HTML and JavaScript. If you don't have these skills, contact your website developer or webmaster.

Read these instructions if you have an AJAX or Flash site and wish to use Yandex.Metrica:

  1. In order for Yandex.Metrica to register important changes to a page, analyze the logic of your site and insert a hit function in the appropriate parts of AJAX and Flash code so it’s triggered each time you believe the page has changed.
ym(XXXXXX, 'hit', url[, options])


Default value



url *


Current page URL.



Field for the options object


The callback function to call after sending pageview data



The context accessed by the this keyword in the callback function



Session parameters



The URL that the user loaded the current page contents from

options.title document.title


Title of the current page

ym(XXXXXX, 'hit', '', {title: 'Contacts', referer: ''});

If you want to register a goal completion for a specific action on the page, use the reachGoal function.

If you were unable to independently check the tag, follow the recommendations below.

This might happen for the following reasons:

  • The tag is installed incorrectly. For example, the CMS modified the code snippet. Reinstall the tag or contact the support service for your CMS.
  • Broken scripts are preventing the Yandex.Metrica tag from working on the site. You can check this in the browser console.

This means that information is being transmitted to Yandex.Metrica. However, the data might not be shown in reports for any of the following reasons:
  • Data is sent to a tag with a different number.
  • The Filters tab in the tag settings has overly strict filters defined. Remove unneeded filters.
  • The Filters tab in the tag settings has the Don't count my sessions filter enabled. This means that the tag doesn't register your own sessions. Try accessing the site with your browser in “incognito” mode.
