How quickly Google finds keyword from Wordpress blog ?
Answer: until web crowler detects the site and the keyword and dedicates the place for Your site among the keyword competitors. In my experiment: about 6h in local web market – google.lt .
Keyword: is arti (which means title of famous lithuanian modern music festival)
Search result: http://www.google.lt/search?hl=lt&q=is+arti&meta=
This search finishes in one of my projects – jazz radio Gaudeamus – www.gaudeamus.ktu.lt .
