Protocol: This specifies the method of accessing the resource (e.g., HTTP, HTTPS).
Domain Name: This is the name of the website (e.g., example.com).
Path: This specifies the exact location of the resource within the website (e.g., /about-us).
Query Parameters: These are optional and can pass additional data to the resource (e.g., ?id=123).
For example, in the URL https://www.example.com/about-us?id=123:
https is the protocol.
www.example.com is the domain name.
/about-us is the path.
?id=123 is the query parameter.
What is canonicalization?
Canonicalization is the process of converting data that has more than one possible representation into a standard, normal, or canonical form. This is done to ensure consistency and avoid confusion when comparing different representations of the same data.
In the context of web development and SEO, canonicalization often refers to the use of a canonical tag (rel="canonical"). This tag is used to tell search engines which version of a URL is the main or preferred one when multiple versions exist. This helps prevent issues with duplicate content and ensures that search engines index the correct version of the page.
A canonical tag (rel="canonical") is an HTML element that helps webmasters prevent duplicate content issues by specifying the "preferred" or "canonical" version of a web page. When search engines encounter multiple pages with similar or identical content, they can use the canonical tag to identify which version should be indexed and considered the authoritative source.

When search engines encounter multiple pages with similar or identical content, they can use the canonical tag to identify which version should be indexed and considered the authoritative source.
For example, if you have the same content available at both http://example.com/page and http://example.com/page?ref=xyz, you can add a canonical tag to the latter to tell search engines that the main version is http://example.com/page.
This helps improve SEO by consolidating link equity and avoiding potential penalties for duplicate content.
How can I know if a page has a canonical url?
Using the Browser
Open the webpage you want to check in your browser.
Right-click on the page and select "View Page Source" (or use the shortcut Ctrl+U on most browsers).
Search for "canonical" in the source code (Ctrl+F and type "canonical").
Look for a tag like this: <link rel="canonical" href="http://example.com/canonical-url" />.
Using SEO Tools
SEO Extensions: Use browser extensions like SEOquake or MozBar to easily check for canonical tags.
SEO Analysis Tools: Tools like Ahrefs, SEMrush, and Screaming Frog can crawl your site and report on canonical tags.
Using Developer Tools
Open the webpage in your browser.
Right-click on the page and select "Inspect" (or use Ctrl+Shift+I).
Go to the "Elements" tab and search for the canonical tag.
By using these methods, you can easily determine if a page has a canonical URL set.
What is the relation between canonical tag and internal linking?
Canonical Tag:
Helps prevent duplicate content issues by specifying the preferred version of a webpage.
When multiple URLs have similar or identical content, a canonical tag points search engines to the main version.
Example: <link rel="canonical" href="http://example.com/main-page"/>.
Internal Linking:
Connects different pages within the same website, helping users and search engines navigate and understand the site's structure.
Internal links distribute page authority and guide users to related content.
Example: <a href="http://example.com/related-page">Related Page</a>.
Both work together to improve site navigation and SEO.
Canonical tags prevent duplicate content issues, ensuring the right page gets credit.
Internal links boost page authority and help search engines understand content relationships.
Used together, they enhance user experience and search engine understanding, leading to better ranking and discoverability.

Can I delete automatically duplicated contents?
Yes, you can automatically delete duplicate content using various tools and methods. Here are a few approaches:
Content Management Systems (CMS): Most CMS platforms like WordPress offer plugins and extensions that can identify and manage duplicate content.
SEO Tools: Tools like Yoast SEO, SEMrush, and Ahrefs can help detect duplicate content and suggest improvements.
Custom Scripts: If you're comfortable with coding, you can write scripts in languages like Python or PHP to scan your website for duplicate content and remove it automatically.
Each method has its pros and cons, so it depends on your specific needs and technical comfort level.
How google considers canonical urls
Preferred URL: Google looks for signals indicating which URL the site owner prefers as the main version. This can be specified using a canonical tag (rel="canonical"), redirects, or sitemap entries.
Content Quality: Google evaluates the quality and completeness of the content on each page to decide which one is most useful for searchers.
Consolidation of Signals: Canonical tags help consolidate signals (like backlinks) to the preferred URL, improving its ranking potential.
Crawling Efficiency: Google crawls the canonical URL more frequently, reducing the crawl load on duplicate pages.
By using canonical tags, you can guide Google to the correct version of your content, improving SEO and user experience.
