The rate at which search engines recognize and index website changes varies depending on what
actions you take.
If you were to publish a new landing page or blog article today, and take no other action, search
engines would probably take about three days to a week to find and index your content.
Now, that doesn’t mean that search engines will necessarily know how this content connects to other
areas of your website or how important it is compared to other categories of content. Even internal
links don’t necessarily inform the crawlers how this page integrates with the rest of your site.
If you want search engines to recognize new content and understand how it relates to your overall
website, as well as how it supports your overall SEO efforts, you should create and implement a new
XML Sitemap and submit it to your Webmaster Tools profiles.
If you publish new content constantly (such as a daily blog post) and you want search engines to index
every unique article without having to constantly create new XML Sitemaps, you can use a particular
type of code called, “Pubsubhubbub.”
This form of code, when implemented on the back end of your website, sends an immediate signal to search engines that alerts them to each individual form of content that’s published, as it’s published.
