As a new user on steemit.com you Start with 3 STEEM POWER and that means that your vote is worth just about $0.000157 Steem Dollars and that is only when you are at 100% voting power, so don't go all out voting for hundreds of articles on the first day
No need to give all your votes for articles published by whales that will surely generate a lot of rewards, because with your small initial Voting Power you are still not very likely to get any curation rewards
Try to vote for less posts per day, but for better articles (10-20 per day) and go for articles that you like even if they end up with less votes and reward you can still manage to earn more curation rewards from them
Try to vote after the 30th minute after a publication of an article to maximize the reward for your vote and avoid any early voting penalties
Posting Tips
Do note publish more than 4 articles per day, otherwise you get smaller rewards for the additional posts you make as a kind of penalty - the idea is to stimulate the writing of fewer, but higher quality posts
Use tags that are related to the content you publish, don't go for tags that are popular at the moment just because you think this will generate more exposure for your content
Try to include an image and not just write text, the right image can help you catch user's attention better than just when writing a good article that is text only
Proofreading your article before posting it can be helpful, especially if you are writing in English and that is not your native language
Formatting the text using simple things like headings, bold and italic text, quotes, using the right size of images etc. can make your publication look more professional
Other Useful Tips
There are a lot of helpful websites that offer tools for making your steemit experience better such as the Steemd Block Explorer, the Steem Stats or the Steem Dollar and many others, so you might want to give them a try and see what extra information they will provide you
Read more about the interest rate for the Steem Power you are have and the Steem Dollars that you earn by posting as it helps further grow your voting power and earnings just by holding it
You might want to read more about Mining Steem as this is also a way to help you increase your Steem Power over time if you have some spare CPU power to dedicate to that
Don't think only about money, the rewards you can get should be just an extra thing stimulating you to contribute to the community and not your main goal
Don't give up, not after a day or two or after posting a few articles that you spent time and effort and they do not end up very successful, keep trying and learning as you go
