Hello Friends , Bigapplecard.com is going to cahce daily but this pr is only 3 and visits are also very low. ..........? Thanks
This is because you might be updating your site on daily basis. It does not affect your PR or google traffic. Google is just visiting you daily to find fresh content added to your site. that's it.
Google does not have indexed all your pages, it is visiting daily to index remaining page> try searching with site:yourdomain.com in google.
There is not much relation between how frequently Google caches your site and how good it ranks for keywords. Keyword ranking is gained by good backlinks, if Google caches your site frequently it does not mean your site will start to rank in top position for good keywords, for that you will have to work hard and develop good quality backlinks.
In my mind i think you are updating daily in your website so that your website is caching daily.Google like the changes so that our website caches daily.
