Ok I had a recent video that literally a week later was on page one for keyword which was competitive and now it’s fallen way off serps. I’ve dug around and heard that GGle/YT in Feb did an algo change. All I know is I was so happy and then depressed as nothing in the video had changed…Any comments.

7) Social Engagment - Likes, Comments, and social shares are the name of the SEO game. If you have a high likes to dislikes ratio then Youtube will favor your video so the goal is to get as many likes as possible and as many comments as possible. I'm not going to go into detail here as I cover this in this "Youtube VIDEO SEO" tutorial so pay close attention to the end of the video.
Ensure that the pictures on your website have file names which include the target keyword. Also, your target keyword should be part of your image’s Alt Text. This will improve optimization for your article and also create a clearer picture for the search engines to the relevancy of your article/page. Images are an important component of any website as they make pages visually attractive as well as informative. Optimizing your images should naturally boost your ranking. Also, your image will get a high rank in Google image search.

One of my favorite ways to give content a boost is to run ads on Facebook targeting people with interests that are relevant to the content. It’s fairly low cost since you are offering a free piece of content. By targeting people with relevant interests to your content, you drive the right people to the content and into the top of your funnel. And if your content resonates with them, they’ll share, link, and engage with the content in ways that will help Google see its value.
