When an advertiser and publisher comes
together to work together then they need a code which can help the advertiser
to know how effective the ad campaign has been for him. Using a code or a tag
on the advertisement would help the advertiser to count how many people have come
to his site through the ad. The publisher also uses a tag or code to count the
number of people who may have clicked at the ad and have been directed to the
advertised site. The publisher’s tag count may however vary from the
advertiser’s tag count due to server errors. In order to avoid the confusion
here, the publisher and the advertiser opt for 3rd party tags that
can provide him with a mutual answer. They can both use the 3rd
party tags or scripts that are provided for free or at a very low price. Setting
up the 3rd party tags is quite easy as they are well developed and
come along with installation guideline. The third party tags help the
advertiser to collect the visit statistic and also help him to know from where
the traffic came. Most of the website relies on them to get the accurate visit
statistics.
