Bid Reducing % / Frequency

Just wanted feedback from others on how frequent your reducing bids and at what % of low end suggestive?

At the mo my strat is = Wait for 100 clicks, then drop 10% below the low end suggestion every hour..

Look forward to your responses

I do about the same thing, i would say closer to 20% lower than the suggested bid, and i drop between 7-10 cents depending on the niche, and how competitive it is.
More competitive = closer to 6-7 cents drops
Less competitive = closer to 10 cent drops

Stack just an example say I'm bidding $1 and after 100 clicks it's suggested is 0.30-0.40 and my avg cpc for that ad is 0.30, would it be best dropping the bid to say .24 straight away or are you saying drop it gradually from the $1 bid between 7-10cents an hour?

I was curious to when you stop the reducing because as ctr drops sometimes when you go into your ad, say your bidding 0.10 the suggested stays above your bid, call it 0.20-0.30 or whatever. Do you just keep track of volume and keep lowering until you see a reduction then up it again to the previous bid to try and keep it steady?

I would be interested in the answer as well. Sometimes I get a lot of traffic but once I lower my bids a little bid so I can have better profitability my traffic decreases.

Also one thing I was curious about is when you have a set of ads going well and your bidding under the suggested, what do you do when your traffic begins to dry up because of your ctr is constantly dropping. Like today I had an ad start with 0.30% ctr and I've been reducing the bids and the ctr is now 0.16% - is it time to rotate more ads into the process? I am taking the time of day into account and will be pausing it shortly to turn back on tomorrow at the peak time.

@Rich how big is the target cap? The reason your ctr dropped is because you've lowered your bid so much that fb decided to show the impressions to the same group over and over, so then the same people see the ad multiple times. The frequency is higher therefore smaller ctr.

The reach is around 450,000. I did follow what most people do and wait for 100 clicks minimum before touching the bid then reducing it 10-20% below the minimum suggested and lowered it every hour or so.

@rich

For the example you mentioned, i'd drop the bids by 20 cents every 30 min in that case. You don't have to do it this way, it's just i've noticed i've dropped bids by too large a gap before and the ad just stopped reciving traffic, had this happen a couple times actually. So i'd drop gradually still, but if the difference between you current bid and suggested bid is 70cent and you have a high CTR you can drop much faster and by larger numbers, so to play it safe don't drop the whole 70 cents with 1 bid adjustment, in my eyes it's a bit risky.

Do you just keep track of volume and keep lowering until you see a reduction then up it again to the previous bid to try and keep it steady?
Yep. Pretty much lets say i have a demo of 100,000 and a CTR of 0.04. I'd say after 5000 clicks at the lowest bid possible the traffic might slow down a bit because CTR is dying down, so i'll up my bid by 1 cent to combat this, and continue as long as the ads profitable. ..but this is also when it's time to get in some more testing and find the new ad/angle that can keep it going at a much higher ROI.

How sure are you about this, you think facebook purposely shows your ad to the same people when you lower your bids past what they feel is a fair bid.. doesn't make sense. Facebook may give priority spots on pages to top bidders, but they won't completely hide your ad from new eyes.

@stackman It's just a thought. With the new interference, I had a few ads with high similar ctr, and so I started dropping the bids. The frequency was at around 1.5, but when it settled down, I dropped my bid lower, and the frequency shot up to 3-4.5 which indicates that facebook wants me to bid much more just to decrease the frequency. I'll have to test this out again, and I'll see what happens.

@ stack - when you up your bid 1cent do you tend to see the ctr rise again?

Has anyone tested not lowering bids? Reason I ask is I had a camp that lasted 5 weeks and I never touched the bid.....I bid 5 cents over the max suggested when the camp started and I never changed it......bids held steady at around 10- 16 cents for about 5 weeks.....

was a large demo 6mil or so.....but I also did this with other camps with a smaller demo....and still had the same results the ads just didn't last as long......2-3 weeks

Was US traffic
