Why this matters
Unstable URLs with session identifiers or excessive parameters cause indexing problems and dilute SEO signals.
Hypothetical standard operating procedure
Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.
- Review URL patterns sitewide to detect session IDs or unnecessary parameters.
- Configure the web server or CMS to generate clean URLs without session data.
- Set canonical URLs correctly to point to preferred versions.
- Use robots.txt or parameter handling tools to block crawl of parameterized duplicates.
Watch for
Multiple URL versions of a page confuse Yandex and fragment link equity.
