Example of a meta robots noindex:

<meta name="robots" content="noindex">
Example of x-robots noindex tag in the header response:

HTTP/1.1 200 OK
X-Robots-Tag: noindex


So, the final step is to replace all of the spaces with hyphens. HTTPS encrypts data sent between site Belgium Phone Number List visitors and your web server.

I don’t want users to access these pages. See the restricting access section.
I need to consolidate signals like links. See the canonicalization section.
Removal option 3: Restricting access
If you want the page to be accessible to some users but not search engines, then what you probably want is one of these three options:

some kind of login system;
HTTP Authentication (where a password is required for access);
IP Whitelisting (which only allows specific IP addresses to access the pages)
This type of setup is best for things like internal networks, member only content, or for staging, test, or development sites. It allows for a group of users to access the page, but search engines will not be able to access them and will not index the pages.

When you might need a different option:

I need more immediate removal. See the URL removal tool section. In this particular case, you may want more immediate removal if the content you are trying to hide has been cached, and you need to prevent users from seeing that content.
Removal option 4: URL Removal Tool
The name for this tool from Google is slightly misleading as the way it works is that it will temporarily hide the content. Google will still see and crawl this content, but the pages won’t appear for users. This temporary effect lasts for six months in Google, while Bing has a similar tool that lasts for three months. These tools should be used in the most extreme cases for things like security issues, data leaks, personally identifiable information (PII), etc. For Google, use the Removals Tool and for Bing, see how to block URLs.

You still need to apply another method along with using the removal tool in order to actually have the pages removed for a longer period (noindex or delete) or prevent users from accessing the content if they still have the links (delete or restrict access). This just gives you a faster way of hiding the pages while the removal has time to process. The request can take up to a day to process.

Removal option 5: Canonicalization
When you have multiple versions of a page and want to consolidate signals like links to a single version, what you want to do is some form of canonicalization. This is mostly to prevent duplicate content while consolidating multiple versions of a page to a single indexed URL.

You have several canonicalization options:

Canonical tag. This specifies another URL as the canonical version or the version you want to be shown. If pages are duplicate or very similar, this should be fine. When pages are too different, the canonical may be ignored as it is a hint and not a directive.
Redirects. A redirect takes a user and a search bot from one page to another. 301 is the most commonly used redirect by SEOs, and it tells the search engines that you want the final URL to be the one shown in search results and where signals are consolidated. A 302 or temporary redirect tells search engines you want the original URL to be the one to remain in the index and to consolidate signals there.
URL parameter handling. A parameter is appended to the end of the URL and typically includes a question mark, like ahrefs.com?this=parameter. This tool from Google lets you tell them how to treat URLs with specific parameters. For instance, you can specify if the parameter changes the page content or if it’s just meant to track usage.
