Our company is an eCommerce site for aftermarket automotive accessories, we have been posting videos on our site. On some pages we have videos embedded from Youtube and on other pages the videos are embedded but in a Popup Image Class. Below I'll provide an example of one way we put the popup image class on our site <iframe id="vidf" style="display:none;" width="460" height="320" src="//www.youtube.com/embed/MattCutts?rel=0" frameborder="0" allowfullscreen=""></iframe> Now concerning SEO would it be better just to embed a video the traditional way or use the popup image class? The reason I ask is because the popup image class hides the video on the page with an image on top then once you click that image the video pops up. Can Google still crawl/see the video? What would be best practice for SEO?

Our company recently started making videos and posting them on our YouTube channel. Should we include the YouTube videos to our sitemap for our main domain? Thanks,

We are in the process of correcting our site in hopes that Google will rank us higher in the SERP. We have many pages that have multiple H1 tags or no H1 tag at all. How important is the H1 tag? Will it help us increase our ranking on Google? Thanks

What is the best way to handle special characters? We have some URL's that use special characters and when a sitemap is generate using Xenu it changes the characters to something different. Do we need to have physically change the URL back to display the correct character? Example: URL:  http://petstreetmall.com/Feeding-&-Watering/361.html Sitmap Link:  http://www.petstreetmall.com/Feeding-%26-Watering/361.html

Our company is in the process of updating our sitemap. Should we include or exclude canonical links.
