Caching Crawl Score will report on the caching methods being used on your website so you can be sure your content is being delivered in a timely fashion to users and search engines. Proper use of caching can have a massive effect on both the user experience and the way the search engines crawl your site. The “Last Modified” date is generally hidden from the user when using a web browser but most browsers will check the local cache to see if a page exists and the Last Modified date has not changed – if not, the web page will not be downloaded thus increasing performance. A search engine crawler will do exactly the same thing and will therefore use its resources to crawl new content rather than re-download unchanged content. “Expires” and “eTags” are used in the same way although “eTags” are used less widely by search engine crawlers.
