How do I get Google to index changes made to my website's keywords?

I have made changes to my website's keywords, 开发者_运维技巧description, and title, but Google is not indexing the new keyword. Instead, I have found that Google is indexing the older one.

How can I get Google to index my site using the new keywords that I have added?

Periods between crawling a page vary a lot across pages. A post to SO will be crawled and indexed by Google in seconds. Your personal page that hasn't changed content in 20 years might not even be crawled as much as once a year.

Submitting a sitemap to the webmaster tools will likely re-crawl your website to validate your sitemap. You could use this to speed up the re-crawling.

However, as @Charles noted, the keywords meta-tag is mostly ignored by Google. So it sounds like you're wasting your time.
