I am interested in using real time analytics and also stuff like heat map software on my site for my small business however, I am worried about the amount of extra calls it will take by adding these new scripts..
I read that its possible to put them onto one and call it once..
How would i do this? Is this also possible for JS plugins as well (wordpress user)
Have a look here:
Regarding JS plugins in wordpress, I suppose you'd have to edit your WP template for this, but perhaps you should check out the wordpress plugins website, they might have a(nother!) plugin for this.
