Do You want to know how to find exact date of web page published on internet -

Getting a website in your research paper or essay can be tricky and frustrating, but there are a few techniques you can use to find the publication date.

Keep scrolling to see if the date is listed below the secondary headline or image.
Some articles may have been updated after their publication date. When this is the case, you should see a disclaimer at the beginning or the end of the article that says when it was edited and why.

How old is a web page

Because Google can crawl any page the moment it is published on the Internet, the indexed date appearing in search results is often accurate.
