The first thing I've noticed is that you need to proofread. As mentioned above, capitalize the letters. You already noted that your proofreading has improved, so I won't bother to preach. Just know that grammar, syntax, capitalization, etc. are all what is first noticed (or at least from what I've seen), and so it's like a "first impression" of your article.
Which is the same with the opening paragraph. Keep it interesting. Even if the topic is dumb as all hell and you couldn't care less about it, pretend you do. Act while you write. I've written SEO articles about hair loss and I'm an eighteen year old girl.. clearly no interest, but you have to make it engaging to read. Remember that these articles may be for niche audiences, but those audiences are very interested in what they're researching. Give them what they're looking for.
You have the framework all here, but it just seems forced, like you added on extra sentences in order to meet a word limit. "many bloggers went to their local Starbucks to write a blog post while sipping on their coffee." That wasn't pleasant to read. Maybe something like, "With the popularization of the internet, coffee shops like Starbucks became a hit for writers looking to relax and sip on coffee while they worked." Not exactly like that, obviously, but try to make it engaging. Also, try to use words that make people want to use something. i.e. in my revised statement, there are words like "hit," "relax," etc. Words like that make people say, "Oh! Hm, that sounds cool." Think psychologically. It's helped me out a lot.
And do not do not DO NOT use "I." NO first person. None. Nada. I don't know if anyone mentioned it, but I'm just going to stress it anyway. No first person. Ever. You can come up with another way to word it. Third or second person, depending on what is preferred. "How Can I Stop This?" No. Even in this context, no "I." Try: "How Can This Be Stopped?"
Coffee can act as a diuretic. I thought.. diuretics were meant to make you go to the bathroom more, in which case your fluids are increased because you have to go all the time? I may be wrong here, though, so you can disregard this.
Also, "making you fatter!" No. Do not insult your reader. Find a nice way to say it. "making you susceptible to more calories than your body is in need of" is a much more pleasant way of saying that.
I don't mean any offense in anything I've said. I sincerely wish you the best of luck and may your writing skills prosper.
