does google spider craw in the website with less traffic? and usually how long would the new site get index?
it is affect by the number of link point to your site. Traffic doesn't have anything to do with the frequency of spider craw
There was time when it took really long to get into the index on major SEs, but nowdays it is a matter of days really. In particular, as my stats tool shows, robots are constantly crawling the site, often revisiting the same page twice a day... Different observations?
