Every  Website Design company use either the push or the pull method of Digital Media marketing for achieving the best results.  Each of these methods has its own pros and cons.  Advantages of pull system are that the file size is unrestricted and there are not additional requirements.  In addition the technological requirements are on the lower side. On the downside is the requirement of marketing and non-availability of tracking for the visitors.  There is no personalization that will induce the visitors to come back. Sometimes the Website Design Agency also uses push method where the advantages are personalization, high rate of conversion and detailed tracking.  Requirements of opt-ins and ease of blocking combined with requirements of delivery technologies are the downside of the method.
