Okay this soapbox sadly, is going to point fingers so people can learn from this. I don't like having to point fingers but it seems no one gets the message across if it isn't done.
What is bulk posting?
It's when you post multiple things all at the same time. So when you do that the keywords you give are going to be the same for every single thing you post.
Why do people bulk post?
Well the excuse used can be "I want to share great content with others" but really it turns more into a quantity over quality.
Why is this harming keywords?
When people bulk post they only put a general amount of keywords in that can sum up all icons but not put specifics to them.
Now onto showing you an example of how this is. This is only one example, from one spot, from one user. It happens on pretty much ALL spots though and from different users.
This whole spot in general I would say is a breeding ground of misused keywords (or none at all) and bulk posting.
the office, season 4, episode 14, icon
keywords you should use though in an image like this is:
who's in it? Dwight and Mose
additional things in it? Raccoon
episode name? Goodbye, Toby
Saying who is in the icon in your keywords is one of the most important things you could do. People don't just go and look for icons of season 4, they want to find a specific character they like easily.
Please remember this was not to attack anyone, it was to present a clear example of what should be done and the best way I can do that is through something that has happened.
