Does google know every time you change content on your page

What i mean by the question is, so on our home page www.in2town.co.uk we change the article under lifestyle story of the day, if this changes every hour, will this encourage google to visit that page more often or will then just ignore that and just visit each day

would love to hear your thoughts on this

Yeah, it seems you may be a bit more focused on a symptom, rather than on a cause.  Authority is a function of your link profile and is Moz's interpretation of PageRank.  The greater your authority, the more often you get crawled, and the greater your opportunity to rank higher for more search queries.

since the update of my site, things have been a bit funny. i was seeing my site get crawled every four days and now sometimes it is daily or every two days. is there anything i should do to get it crawled more often.

You say about the authority, is there anything i should be doing to improve this.

The frequency Google crawls your site/pages tends to be based on authority, rather than on how often it is updated.  So if your authority dictates that your page gets crawled on a weekly basis and you change the content on a daily basis, not all of that content will get indexed.

You can see when the last time a page was crawled by using this search  cache:example.com/page and you'll get the last crawl date at the top of the page.  You can also look through your server log files to see crawler activty.

You mean to say that the article on home page is updated with new article every hour

Yes, as long as the content and snippet get changes and backed with Authority links - it will enable search engine to crawl website more often in lookout of fresh content. **Note - **Search Engines crawl site basis the source code, so as long as the content is changing frequently - so will the crawl too
