Build generic anchor text like watch this video with low pr backlinks and use the high pr backlinks for your main keywords and lsi keywords. Related keywords does wonders for videos. Keep your anchor text ratio at 10 main keywords, 50% url and 20-30 generic, click here, watch this video and so on. Build backlinks with Generic and url first everyday for 2 weeks and keep it consistent, then once you can find your video with serpfox.com then you start with your exact anchor matches and you continue to do generic and url backlinking. Don’t buy views unless you know your video won’t get deleted. I never buy views. Just vseo. Hope this helps.
Longer content not only helps in adding more keywords to it, but there is also a natural emphasis on information. The authenticity of a post increases with longer text, which means that Google would recognize it as something more relevant than a shorter and concise text. As search patterns are synonymous with long tail keywords nowadays, a longer text also improves the chances of your article/website to be on a higher ranking than others.
I have 1 little problem with your claim about longer videos being better. Personally when I’m looking for a how to solution to a problem I prefer shorter videos because then I won’t have to click through the video to get to my answer. I think eventually it will be about offering the best information in the shortest span of time. I think ultimately that the retention rate of a shorter video with the same quality will beat a longer video just because it has less retention.. because people prefer easy and fast solutions. What do you think?
What about subtitles & closed captions? I see in one of your comment replies that you’ve uploaded transcripts of your videos but looks like Youtube has 1 spot for transcripts and another for subtitles/CC. Have you tested both transcripts and subtitles/CC? Also, I know the difference between subtitles and CC but there doesn’t appear to be anyone that’s tested once vs the other. Might be something to test.
It appears that the reason this page from a little-known website is able to rank amongst the bigger players is that the content itself is more focussed. It talks about how to name images for SEO, whereas most of the other pages are more general guides to image SEO—which all presumably mention the importance of naming images correctly, amongst other things.
