The Canonical URL is an HTML link element, with the attribute of rel=”canonical”, located between the <head> tag of the web page.
You may find these URLs as the same URLs but technically all of these URLs are different. Google considers them as a different domain. Thus, to overcome the confusion of selecting the real or main URL, we must have Canonical Tag. Canonical Tag is also used to resolve the issues related to duplication.

Robots.txt file must be placed in a websites’ top-level directory. It is case sensitive. It must be named robots.txt, not Robots.txt. Each root & sub-domain uses separate robots files.

It helps users to connect to diverse data that are relevant to the source page or content. It can be of different types such as keyword-rich anchor, Generic Anchors, Branded Anchors, Image Anchors, and Naked URLs, etc.
SEO best practices dictate that anchor text should be relevant to the page you’re linking to, rather than generic text.
What is Image Alt Tag?
Ans. As we know Google Bots cannot read the images on the web. Therefore, we use the Alt tag with the images so that Google could understand what an image is all about.
The Image Alt text is generally considered as an alternate text for an image, which provides a textual alternative to the web crawlers to index the web page bearing the image.
It is best practice to put your important keyword as an image alt tag. It makes the image more relevant to your targeting keyword or topic.

Also, it is always considered good to get backlinks from the high visiting website. It helps to increase the referral traffic too on the website. The higher the link juice or link points are, the greater would be the search ranking of that web page, as these links make the web page appear very relevant and popular to the Google search engines.
No-Follow Links are those links which tell the Search Engine crawler to ignore the links. It is just the opposite of a Do-Follow link. These links cannot be followed by bots but users can visit the links.
There should be a No-Follow link too on the website but not more than Do-Follow links. If you are getting even No-Follow links from high ranking or visiting websites, you should have links from them. Now Google considers the No-Follow link too. See here what they have said about it.
No-follow link attributes are structured in the following manner:
<a href=”http://www.example.com/”rel=”nofollow”>Link text</a>
