what is equity??

[ProspectedSEO]

I suppose that you meant link equity or link juice. That is a search engine ranking factor revolving around the idea that links can pass value from one page to another. It is not a fixed value because it depends on many factors, linking page authority, relevance, outbound link count and more. So if a high authority website links to a website with smaller DA, that is a vote of confidence in Google’s eyes, and it will rank that website higher.

Link equity, once colloquially referred to as "link juice," is a search engine ranking factor based on the concept that certain links pass value and authority from one page to a different. Links that pass equity are one of many signals that Google and other search engines use to determine a page's rankings in the SERPs.
