Jeewan Garg: if we change the coding ( intially it has been made in html table ) of any old website. Does it impact my ranking in Google also
Federico Sasso: You would likely notice an overall improvement in page download and rendering time, which might cause a slightly positive impact in ranking as well. Hint: take the chance to use a responsive layout... preferably before April 21.
Jim Munro: googlebot only cares about the bunch of flowers, not the method of delivery, Jeewan. If the page content remains the same, changing the coding should make no difference at all unless the new code loads the page faster in which case the change might be beneficial. :)
