As of the moment, one of the latest and therefore hottest Search Engine Optimization trick added to the book is called re-targeting. This technique is similar to the previous services of a regular SEO company for displaying purchase ads with a few tweaks and twists of its own as an improvement.
People already are well aware of ad displays as an effective means of targeting specific traffic online. However, specific is still broad on that part of the equation. Whereas in re-targeting, there are certain measures to ensure that only visitors who have already had a history of buying products similar to the one you are marketing.
The way that this happens is by positioning a re-targeting pixel on a specific or scattered manner. When they view that page, they will be added to the list of “audiences”. Once the tracker is in place, you will be able to follow them as the campaigns are showed on the other sites they visit thereby increasing your popularity. If however, that will be too much for your “audience”, they will have the option to “burn pixel” which has an obvious purpose and needs no further explanation.
In order for this to be a true, cocked and ready to fire SEO weapon, you must first build up some audience. This will work more effectively your way. In addition to that, try to research what techniques by an SEO company are more influential such as the option of the same or different pixels meaning various ads being shown to your audience on each site.
