Google is more diligent than I absolutely, in terms of robots, actually. Google is checking if every website owner is diligent enough in adding new content to their website, even maybe a log or a diary. However in general, when page ranking is declining, it is not a plunging, unless a website is punished by Google. Original content still matters and Google still gives credit to original websites that bring convenience to thousands of customers by using online service.

During this low season of business, I actually took a job otherwise than the website running and marketing. After two months, I found my ranking on google drops somehow but not dramatically out of page No.1s. Thanks to Google. Robots even understand low season and high seasons.
