The only thing that should interest you is if your site is INDEXED, the cache is good for people who want to see some content or information you had in the past, sometimes you can even be lucky to rank good for some old stuff on your site which as been cached.
Index: Getting indexed is the first step your site experiences when search engines crawl and index/saves your site in their database. Cache: Cache can be defined as, when a Spider/Crawler reads your web pages after they are indexed. (to refresh their database in case you have an updated content). Hope this helps.
there is no so much difference between cache and index. But the term cache may create quite distinction for the users.
From cache data you can know that when google spider came on your webpage last time and visit your site. Google's cache is helpful because from that you should know that how often visit your site by spider. You can see the Google cache of your website/web pages like In the Google search result showing the URL that you need to view, click the "Cache" link. Indexing means whatever you can see in search result. If you search web design keyword related to your website and search engine show that particular page related to that keyword in search engine then you can say that google has been index your web page in it.
Indexing : At the first time you site has indexed in Search engines by spider Cache" : After indexing your site the spider crawled for updates of your site. Note: Without indexing cant cache your site for updates...
In a simple term, when search engine bot or crawler come to your page or found any update on site, this process is "Cache". After reading the updated element it stores those new elements in Search Engine's database. This restoration process is "Indexing".
Indexing is a process to make a webpage searchable on search engine whereas the process of caching refers to providing a reprinting content snapshot. For example, if we uploaded a new website, then first of all search engine crawler will read the site and after that, it will store all its contents in its Index Data Base in a different format (by giving priority to the h1, h2, or bold, title, meta tags etc.), it will not place content as it was published. As a result, the site will appear in search results for optimized keywords. Google also takes a snapshot of each page on a website and stores it in a different data base which is known as cache data base. If you click on the “Cached†link, you will see the web page as it looked when we indexed it. while, Google creates the index and the database of documents that it accesses when processing a query.
