I have a bunch of redirects to sites like sharethis, media6, and some random character urls. Most of these are leading to a blank pixel or each other. I know a lot has to do with facebook and needed resources but how would I find out where these are being loaded from? So I can figure out what plugin is causing them and remove it if its not necessary.The last three are the main problem. But when I search the source I can not find them so it has to be some JS thats loading them. Also is there an easy way maybe at the server level (nginx) to access all these resources from my server through a cache or something? Short of changing the code to load them locally.

While in the process of implementing a CSP and defining the allowed sources, I was shocked to find the total number of resources ShareThis calls. At the time of writing this, I counted a total of 39 domains and subdomains it uses.

Not a big surprise anymore why ShareThis was causing my slow page load times. From what I found, the majority of the calls are for ad and user habit tracking pixels. No wonder they're a free service, they're probably getting paid big bucks from companies to track what you’re doing. Though, I understand they need to connect to the various social network APIs to grab numbers, I don’t think they need to add tracking pixels for advertisements and user habits.

An example is adadvisor dot net and crwdcntrl dot net. Their domains used by Targus Info and Lotame which is an advertising company that is part of a network of sites, cookies, and other technologies used to track you, what you do and what you click on, as you go from site to site, surfing the Web. Over time, sites like adadvisor.net and crwdcntrl.net can help make an online profile of you usually including the sites you visit, your searches, purchases, and other behavior. Your profile can then be exchanged and sold between various companies as well as being sold to other advertisers and marketers.

Alternatives to ShareThis

After finding out everything ShareThis is doing, it was time to find some alternatives. Here’s some I’ve found that seem to be less resource intensive—though may still load ad and user habit tracking pixels, not nearly as many as ShareThis:

AddThis dot com AddToAny dot com Shareaholic dot com Share42 dot com (very basic, no third-party scripts)

  • I use addtoany now. But I was getting these before I added it. I was hoping to have a way for the server to tell the browser to ignore those links or proxy all the connections through my server so I can maintain a cache.

I ended up solving this using the WP-Do-Not-Track plugin. I was able to black list all the addresses I did not want loaded. it works great and does not seem to change my page load speed.

A lot more than add to any was causing these.

  • This is the answer to my problem. Everything that had to be loaded was locally cached. All this stuff in my list was extra tracking code and it was all blocked by wp-do-not-track. Problem solved.
