As an answerer has correctly pointed out - readers have low attention spans, especially when they r using the internet. You can follow the guidelines given below.
Write articles with word limits stetching frm 500-700words. This is supposed 2 be the ideal length of a readable article.
Don't beat around the bush, make your point quickly and explain your point.
Use compelling interesting eye catching titles that contain the keyword/keywords at the beginning.
Use primary keyword/s and secondary keywords.
Research, research and research even more and fill yr article with sunstantial and solid info, so that it is unputdownable.
At tymes, too many pictures n videos kill a hub's appeal. Reserve your pictures n videos for manuals and travelogues.
Write and arrange your points or info in such a manner that readers don't hav 2 search 4 them. That is why bullet points r so helpful.
Paragraph length should vary between 4 and 6 lines, if writing in ARIAL 12. Paragraphs shud be of equal length 2 create a visual appeal.
Finally stop worrying about hubscore n concentrate on improving yr article quality. Hubscores always fluctuate.
I've only been here for a week or two so there might be more to it than I know of, but it helps to read and comment on other people's hubs and to link other hubs within your hubs. They'll return the favor mostly by reading and commenting too.
After reading your hub,that has a lot of information on it. I can only recommend another title.
I've glanced through your hub and while it does present good information, you do need to condense it and reduce the amount of words. Speaking as a freelance editor, people have low attention spans and want to get to the main points quickly. Also consider redoing the title to something like: "I've made lots of money online - here's how I did it".
Read that section, and I'm sure you will find out what is hurting your Hub.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
