Ah - Contest . . .
As one of the many Contest "JUNKIES" of ECF, I can tell "You" that there are many different types of contest that many people enjoy and those that stand out a little more then others are ones that (in general) . . .
1)
Have Very Clear and Defind 
, especially when the Contest Starts & Ends
(There are "Contest Police" out there

- Just Sayin' . . .

)
2) The
"Winner" is picked at "RANDOM" (use the Random.org & Video is posted in Contest
Thread)
3) Are Not To Long or To Fast (especially Do Not take months, unless it involves a series of Prizes)
4) Are
Limited to the Number of Entries a person is allowed - especially per day (You will get hit hard by just a few people)
5) Are
Themed Based (especially during Holidays), or
Takes Some Initiative and/or
Have "Substance" to the entries (Those "I'm in entries" Contest are nice, but boring, also - IMO - any contest where a predetermined post number DO Not Really give people a fair or equal chance to Win - are a NO NO . . . Just sayin' . . .

) .
6)
DO NOT Take People to Social Media Sites (There are many people who vehemently detest Facebook/Tweeter/etc.)
I hope this information is somewhat helpful and that
"You" have just as much FUN running the contest as those that enter them . . .
Oh - BTW: Really like the title of this Contest
"ITS ALL ABOUT ME" . . .
