This is because the indication given by the tags is captured by bots only at the very moment in which they perform a new analysis of the content. Finally, check whether the pages you have indicated with the noindex tag are not already marked with disallow in the robots.txt file , because this does not prevent the page from ending up in the sweden phone number search results.
Now let's look at the canonical tag. Using the canonical tag on a piece of content tells Google that the content found on the page indicated after the tag is the most important and the one on which attention should be focused. One way to use the canonical tag correctly is for example when you have a mobile version and a desktop version of your same site .
By choosing from time to time which is the canonical version of the URLs you guide the bots better. However, keep in mind that, as often happens and in particular as happens with tags, the indications that are given to the bots, even the canonical, could be ignored. In fact, this is not a rule that the bots are obliged to return to the search engine but rather a suggestion.
The search engine in fact reserves the right to show a user, based on the search that he has performed, a different page than the one you would like. This could again be what happens with the mobile desktop versions.
If you mark the desktop site page as canonicalized but a user searches from mobile, it is clear that this user will be shown the mobile version of the site and page. If you want to know more about this tag we have a specific guide .
As far as best practices are concerned, here we will simply remind you that canonical elements should not be inserted in robots.txt files and that, as also reminded by the specific section of the site dedicated to developers by Google , different URLs should never be specified for the same content using different techniques.
The ranking is the position that in the SERP, therefore in the results of user searches, occupies a content that has been indexed by Google to stand out thanks to the presence of a specific keyword.
