According to a recent Tweet that was published by Gary Illyes at the end of last week, adding a video to your web page should have no effect whatsoever in terms of improving your search result positions.
The actual Tweet is as follows:
Although Gary himself is the first to admit that he can “get things wrong” from time to time, on this occasion we are inclined to agree with him.
Of course, that’s not to say that videos are a bad thing or that they will hurt your page ranking, it’s just that they won’t help push you up the SERPs on their own.
So, Are there any downsides to video?
There is one negative aspect associated with having on page videos embedded in your content and that is page load speed.
The reason for this is that if the video is set to play automatically, then it will obviously need to stream and buffer, and this can slow the delivery of your content dramatically, particularly on mobile devices or desktops with a connection speed that is not up to scratch.
The solution here is to make sure that the embedded video only starts when the user decides to view it.
With the points above in mind, it is only logical to assume that you would be much better off spending your time optimizing your onsite written content by making sure it is relevant, grammatically correct and genuinely worthy of your readers’ time.
