What is Canonical issue and how to check the indexed links in google ?

Answer 1

Canonical Issue :

A canonical URL or link is an HTML tag which is incorporated within the html file to avoid the duplicate issue with the two different variations of the domain which is with and without WWW.

For illustration: http://example.com/index.html and http://example.com (or) http://www.example.com might not redirect to the same page, since the two urls are containing the same content which we can consider as a Home page of a website, As google is operated via bot containing the algorithmic rules , considers as a duplicate page or duplicate content.

Answer 2

Canonicalization is nothing but redirecting the multiple urls in to the single URL. Every web page requires a canonical URL reference to the search engine to pick up the best URL among the several urls and it usually refers to the home page.

If the web page is having multiple urls with the same content, all the links are redirected into one URL of all the other duplication pages. To remove the duplication issues we need to use the canonical tag in head section. Adding a 301 redirection to the web page it helps Google to know which URL is preferred for canonical.

In the set of below links, three urls can be redirecting to one standard URL and this can be done once for page.

http://example.com/

http://www.example.com/

http://example.com/index.html

http://www.example.com/index.html

Indexing is the processes of gathering the information by the Google bots from its crawling activities. Once the documents are process, they are added to the Google search results and if the documents are determined by the good quality of content.

When the user enter to Google search in searching with some keyword than the Google bots search the index for matching pages and returns with some most relevant results. Those results are called as indexed links in Google and also help in order to rank the site in search results.
