Bidbots are used for post promotion activities. Use of bidbots can increase your reputation score as well as your chances of earnings.
Only bidbots cannot make your post profitable. In fact, investments in bidbots can be result in a loss if no generic votes are received on your posts. I observed following things while using bidbots:
If after using bidbots, the price of steem goes down, then the use of bidbots will result in a loss.
If after using bidbots, price of steem rises, then the use of bidbots can be profitable.
If no generic votes are received on a post, then the use of bidbots will bring a loss for you.
Bids should not be send at the last moment because many users can send bids in the same way. It dilutes the voting value of the bot. Also, bid should not be sent if the bot has received 90% of the maximum profitable bid.
It all depends on the "quality of the post being upvoted" and the "amount" you have sent to the bidbot.
The "main" purpose of bidbots is to increase visibility of a post. If you are only sending 1SBD then for sure it will not even reach the "hot" section and no one will be able to see the post let alone have a chance of being upvoted by others. Most likely it will be drowned along with other posts after 5mins of being upvoted by the bot.
The next thing is "quality of the post", if your post is good enough then the moment it reaches the "Trending" or "Hot" section , chances are more people will see your post and will likely upvote it. The downside of course is if your post is of low-quality then instead of being upvoted, you'll be downvoted.
More visiblity = More chances of being upvoted = More profitable
