Do having social sharing icons such as Twitter and Pinterest slow down site speed?

[Pday]

We are debating a redesign of a travel site and wondering whether having social sharing buttons including Pinterest and Facebook above each image would slow down site speed and therefore have a negative impact on our rankings.  We are deciding between having the icons above each image or just in the side bar of all pages.  Many thanks, Penny

I did not test all combinations, but I did determine that it's faster to select the subset that your visitors will use and not to load the myriad of fluff icons.

Christopher, did you test add this against using say Facebook, Twitter and Pinterest tools all separately?  Many need to include 4 to 5 different social media tools, and loading each one of them separately in my experience has typically always been more of a burden on the cover than using even add this.

I think I myself actually moved into primarily using ShareThis, but that only had to do with liking their look and feel better for various projects.

Yes, the vendor you use (e.g. AddThis), the features you use (e.g. number of likes), and number of icons you use (e.g. FB, Twitter, G+) can affect the performance of your page.  FWIW, I dropped AddThis because it was much too slow.  YMMV.  I recommend testing several vendors and feature settings.  Also, you should retest the page performance periodically.

Best,

I have in fact seen a slow down in performance but it depends on how and where you're placing them. I don't think the slow down has ever been enough to have an impact on your rankings, but I've seen situations where it would annoy a visitor.

I've had better luck using the 3rd party services like AddThis or ShareThis.  Sure they have limitations, but for me at least they seem to perform a bit better in terms of speed than if you're using Facebook or Twitter's tools directly (and separately).
