# Changing the primary and alternate site addresses
When you change a site's primary or alternate addresses, it usually takes about a month for the changes to affect the search results. If you followed the instructions for [moving](https://www.yandex.com/support/webmaster/en/yandex-indexing/moving-site.md) or [ungrouping site addresses](https://www.yandex.com/support/webmaster/en/yandex-indexing/address-separation.md) but the search results haven't changed, contact support.

- The primary site address was changed by mistake
The primary site address may change if the old site pages have a redirect or the [rel="canonical" attribute](https://www.yandex.com/support/webmaster/en/robot-workings/canonical.md#set-canonical) referring the site that has become the primary address. To avoid automatic selection of the primary address, make sure that the pages on all alternate addresses redirect users to the corresponding pages on the desired primary address.
- The site is presented in the search results with the wrong URL
This means that the indexing bot has selected the primary site address automatically. Specify the correct site URL for the robot, following the recommendations in the [Moving a site to a new domain name](https://www.yandex.com/support/webmaster/en/yandex-indexing/moving-site.md) section.
- Site domain name changed
- HTTP / HTTPS changed
- The www prefix added or removed
- The moving request isn't accepted
Main reasons why sites are not grouped:
- In the source code of the site that should become the primary site address contains the [attribute rel="canonical"](https://www.yandex.com/support/webmaster/en/robot-workings/canonical.md#set-canonical). Delete it and submit the request for moving again.
- The site is unavailable or responds with a long delay.
- The sites' content doesn't match. Check if the internal page URLs and headers match.
- The site moves to another domain zone without a redirect.
- Site indexing is prohibited in the [robots.txt](https://www.yandex.com/support/webmaster/en/controlling-robot/robots-txt.md) file.
- [Violations of the Search rules](https://www.yandex.com/support/webmaster/en/service/security-threats.md#threats-web.md) are detected on the site. View the details on the [Security and violations](https://webmaster.yandex.com/site/diagnosis/threats/) page in Yandex Webmaster and fix the errors. In two weeks, check that the message about the violation disappears from Yandex Webmaster, and re-send the request.
- The request was sent from the site to move to.
- Internal service error. Try sending the request later.
- Recommendations didn't help
