Crawling and indexing of pages within a website can take some time. While there's no
way to force an update, here are some tips that may help to speed this process up:
Ask Google to recrawl your URLs.
If you are using a Sitemap file, make sure to update the last modification date.
If your site's content is indexed with multiple URLs, resolving the duplicate content issue within your site will generally allow crawlers to find updated content quicker.
