Hi Briona,
I have used a couple of different ones from time to time, the easiest one I have come across is Floating Social Media Links, it comes with 4 standard being Facebook, YouTube, Twitter & Blogger, but it has the ability to create your own as well and add your own social media images.
Hope this helps.
Paul

I wouldn't have any doubt that they would Briona. Like having relevant images, search engines would probably recognize it as valuable and diverse content. As far as traffic, people always enjoy watching videos which help explain/highlight your content. Only my opinion though and Im not sure of specifics. All the best. Jamie

Good question,good comments,Thanks everyone!)

Thanks you guys! I am going to check out the training.

Yes they can, I just wrote a blog for that Boost your website with Youtube

Added to what fvolken said, here is an excellent training video that will help. :) Generating Traffic with YouTube

Yes of course! You should do it. You'll get a lot more of attention if you have your own youtube videos on your website. But very important is to have an own YouTube channel with a good description and the right keywords. the video should also be clickable... in one of the WA trainingsvideo from the last week it's a very good explanation of add links on the youtube Video. So you'll generate backlinks and google likes backlinks... I hope you can understand me...
