Search engines with out effective pinging will catalog your site once and at the bottom of the heap
adding tags and pinging every post will make you more and more money visitors and links
Not pinging will stagnate your site and if there is a glytch or an analygorythem change you may find your site invisable
Search index rank and page rank will ultimately bring ad hits conversions and money in the bank
Mane Shute your site is search optomize a clear title and description are a must
a contact me page is a must
labels are a must
links or a linklist are a must
a list of your most popular posts are a must
categories of your content are a must
non confusing ad placement are a must
when in doubt mimic sites with higher page rank than your site
stay current with a ping : don't just ping once ping every time you post
