To get a rush on a hub or blog is easy. One has to attract attention by one's topic, and by appealing to the kind of people that one is targeting with honesty in one's approach.
Many of us write to influence others, forgetting that most people are experts in their own right, and the more they are made to believe that they have any weaknesses in life, the more they resist a writer's opinions and find a way to debunk them.
A writer must be specific about his or her targeted audience; it (audience) should not be spoon fed with white washed ideas or suggestions, It must be allowed to have room to think freely for itself, and others will be happy to part of that audience.
That is the only way a targeted audience grows; and that equates heavy traffic to a blog or a hub.
For example, millions of Americans love the sport of football, and if one was writing only about the best teams and telling how they have come to acquire that level of accomplishment, which obviously through hard work, the writer is focusing on just half of his or her audience.
However, if weak teams are also mentioned, and refreshing their memory that they have done well during some seasons, and also drawing their attention to the fact that it is not a good manager that makes a team; but the players themselves, they are bound to be inspired.
The writer has covered all his bases; and especially as weak teams have fans too the writer has expanded his target audience threefold; the teams, their followers and the general public.
A writer must put himself or herself in the niche of a painter, and always attempt to view his or her topic through the eyes of his or her audience as well; for painters are never narrow minded.
They paint, using several viewpoints, good or bad, to include almost all that will see their work.
"How did my friend get so much traffic to her blog?" must have been that she has not been selfish in expressing her views, but has attributed some of her salient points to people outside the realm of her expectation; meaning she did not concentrate on those in the ring fighting, but also the crowd watching and how their reactions were
That way, she would have any number of people reading her blog or hub, for having a wider view than someone, who wanted to be just intuitive, and without having any consideration for her readers or anyone, who would come across the blog or hub, ramble on and on from start to finish.
There's nothing more satisfying than getting the traffic she wants.
