I think “casino bonus(es)” is not that bad. People searching for that may be looking for casinos with good bonuses, not only no deposit but also match bonuses. They may be willing to play. They may be looking to extend, leverage their deposit. That’s fine.
The problem is when people search for “no deposit xxx”. That people are not looking to play in general. They are determined. They are determined to not risking any money.
Worse than that are keywords like “new no deposit casinos…”. People looking for that have played in almost all no deposit casinos without making any deposit at all. They’re adding to their search the word “new” because they know they tried almost all no deposit casinos and want to find any new opportunity.
Other bad words are “instant no deposit….”. People searching for that are desperate not only to not risking any money but also to play right now.
I’m not willing to add new no deposit casinos, unless the casino has something more to catch the player attention and to make him deposit.
About other keywords, it seems to me that casino reviews does not attract any reasonable traffic from msn. Don’t know how this keyword is doing on google/yahoo.
One interesting thing is, almost all casinos I have at my websites have bonuses of at least 100% and I also have some with no deposit bonuses. My first real depositing player, played at Cherry Casino, and this casino only offers 30% match. That’s one of the worst bonus offers I have at my sites. Anyway the player choose that casino to make the deposit. Not all people are looking for bigggggg bonuses. That’s good.
