To tell Google and the other search engines that your site has been updated, you can use XML Sitemaps. Our WordPress SEO plugin contains an XML Sitemap module by default that you just have to enable. Go to Settings → XML Sitemaps and click the checkbox (if it isn’t already on):
As soon as you’ve checked the checkbox and hit Save, it’ll give you some options but in most cases you won’t need those. It generates an XML sitemap for all your posts, pages, custom post types and all your taxonomies like categories and tags and (if applicable) other custom taxonomies.
When you publish a new post or page, the XML sitemap is automatically submitted to Google & Bing allowing them to easily (and quickly) find your new content.
Other than most other XML sitemap plugins, this plugin doesn’t generate a static file, which is a very intensive process, especially for large sites. This means there is no “action” on publish, which slows down the publishing of the post. Instead it generates XML sitemaps as a sort of template using WordPress rewrites, which is much faster while also allowing caching plugins to cache the output.
It’s also being smart about splitting those sitemaps up into smaller bits, so Google only has to fetch one new XML “sub”-sitemap when a post is published, because the other sitemaps haven’t been changed, using the date modified options.
From an SEO perspective, it’s better than most others because it also includes the images in each post, which makes your images rank (better) in Google Image Search. It also integrates tightly with the rest of our SEO plugin, meaning that a no indexed post automatically is left out of the XML sitemap, with the option to “force” it in.
Lastly, it has a pretty complete API, allowing us and other developers to plugin extra sitemaps, which means we can do things like create our Local SEO, News SEO andVideo SEO extension. These extensions respectively generate a news xml sitemap and video xml sitemap.

We use XML sitemaps from SEO plugin by Yoast. We also have rss feed, which is enough for fast indexing of the pages. We don’t have problems here.
