help search engines understand the page
content and influence how the page
appears in search results.

summary of the page content.
Robots meta tag – Tells search

25. Keyword density refers to the percentage
of times a target keyword appears in the
content compared to the total word count.
What is keyword density, and what is

content issues by specifying the preferred
version of a webpage.
Use a canonical tag (rel="canonical")
when:
You have duplicate or similar content
on multiple URLs.
Pagination exists (?page=2, ?page=3).
Products have different URLs for
color/size variations.
Example:
If example.com/shoes and
example.com/shoes?color=red are the
same content, add this to <head>:
What is canonicalization, and when
should you use it?
<link rel="canonical" href="https://example.com/shoes">

crawlers on which pages to crawl or
ignore.
