If you are worried about the few words in a news feed or in photo capsules, then your Hubs must be too short!
No one really knows how many words Google wants. Nelle Hoxie, who earns over $2,000 a month with her Hubs, has done some experiments and she has found that Hubs over 800 words do much better than shorter Hubs. In fact, she is now writing Hubs of 1,000 to 1,500 words.
Other successful Hubbers believe that two Hubs of about 400 words each, linked to each other, can be just as successful as one single 800 word Hub.
