How not to develop a Campaign in SiteSpect

The following is an example of a use case and how developers that are new to SiteSpect might be temped to "code it".

You have a requirement for a new Campaign

  • Redirect to a new page
  • Alter the style of some elements on the new page

How you might be tempted to (but please don't)

  • Inject a bit of JavaScript near the top of the page like
  • On the destination page, change the style like
    document.querySelector("#navTrigger").style.display = "none";
    document.querySelector(".m-supernav-logo").style.width = "10.4em";

Since SiteSpect has direct access to traffic, INSTEAD

  • Use a Type: Origin > Type: Redirect Variation

    This is the most performant way to do a Redirect. It will redirect the page on the request before it gets to the Origin.
    Note: if your Triggers need access to page source, you can use a [Response] Redirect, which is still performant.

  • Inject a block of CSS in a <style> block inside the head with a Search and Replace Variation
    #navTrigger { display: none; }
    .m-supernav-logo { width: 10.4em; }
  • Optionally use Search and Replace to remove the HTML that you don't want and/or inject inline CSS into the elements.
  • If you want to make other types of changes to elements that get created by a script in the page (after the page is delivered to the browser), consider using a Client Side Variation. This can work well for elements are are not yet created or otherwise ready when the page loads and it avoids the use of setTimeoout() for example.
