Synchronous Versus Asynchronous Tags
Content-swapping tags, the type used by many optimization vendors, come in two common variations: synchronous and asynchronous tags.
- Effectively block all content below them from loading until the tag returns content.
- Load slower while retrieving content.
- Continue to load the remainder of the webpage while the browser retrieves content.
- Produce flicker while retrieving and loading the new A/B test version.
How To Improve Site Speed
SiteSpect uses a non-intrusive, tagless architecture that is entirely different from any other solution in the testing and targeting space. SiteSpect’s Find and Replace technology makes content changes on request, rather than at rendering. This method allows more power and flexibility, does not require any page tagging, and thus sidesteps an array of performance issues.
