While looking at my site's performance, I noticed that some resources from scorecardresearch.com were loading very slowly. When I disabled addthis, the problem went away, so I assume that scorecardresearch is being used by addthis. I checked out scorecardresearch and it appears to be some kind of user behavior tracking software. Is there a way for my site to opt out of using scorecardresearch? I'd prefer not to load up my site with stuff that slows performance, and I don't want my visitors to feel we don't respect their privacy.
Unfortunately there's no way to opt out of tracking when using AddThis, but you're not the first person to complain about Scorecard Research. I'll let our data team know that they're a performance problem and we'll likely remove their assets.
Scorecard Research continues to be a major drag on site performance...
Thanks for keeping us updated. In the future, could you post test results and examples when Scorecard Research is being slow? This will help us work with them to nail down the problem.
Sure thing. As an example, I ran my site through www.webpagetest.org. Two resources showed a very slow "time to first byte": b.scoredresearch.com-b and b.scoredresearch.com-b2. Both had 302 repsonses. The first had 31ms DNS lookup, 31ms initial connection, 3122ms time to first byte, and 2ms content download. The second had 0ms DNS lookup, 0ms initial connection, 3599ms time to first byte, and 0ms content download.
Could you post a link to those test results?
I noticed this today as well.
Document loaded in ~3s, but fully loaded in ~19s.
Scorecard took ~17s and returned a 302.
Not sure how long these links remain live, but here is the current test:
Also, here are a few showing delays by other components of addthis:
Thanks for the update guys. I'll be sure to let the team know. We're going back and forth with them on their performance and aren't too happy.
We currently use several AddThis widgets throughout our University website.
The inclusion of 3rd-party tracking cookies with the AddThis widget is not something we expected to happen, and it causes us an issue with the cookie legislation. Our users are generally okay with us setting cookies when the data being collected is used by us to improve our websites, even if it's from Google. We don't want to have to ask them if they're additionally okay with a 3rd-party tracking the rest of their browsing habits, which is - from my understanding of it - the reason the cookie legislation was created in the first place.
The more specific point here is that we didn't elect to include scorecard research on our pages. If the cookie continues to be bundled with the AddThis widget we'll have no option but to stop using it.
Any updates on scorecardresearch? It seems that scorecardresearch ends up blocking sites on certain corporate servers, as they are identifying it as malware and as a result, treating the site as a malware infected site. Any comments on this? I'm an avid AddThis user, but if my site (which is a part corporate) is treated as malware on corporate sites, it renders the purpose of the business useless and destroys brand image.
In addition, as Akira and Laura have pointed out, it makes the site painfully slow. It pretty much makes any optimization practices useless.

We're still working with ComScore to resolve this issue. Anyone experiencing issues with ComScore please post as many details as you can - page load tests, the software that's flagging them as malware - so we can work more effectively with them to make sure our tools function as well as possible for as many people as possible.
