Adsense Earnings Pattern. Anybody seeing this?

starts out good, gets worse during day

[fearlessrick]

OK, I confess. I check my stats about 12-15 times a day.

One thing I have noticed is that lately, the morning (I am in the Eastern US time zone) is very good. CTR and eCPM usually at the highest levels of the day. By 2-3 pm, however, things really begin to slow down and continue to do so until late at night.

This is somewhat of an annoyance because I always have high hopes in the morning, only to see them dashed by day's end.

What really astounds me is how my CTR can be 4-5% with eCPM at $6-10 at 9:00 am, but by 10 pm CTR is 2.5% and eCPM is $2-3.

Are people more inclined to click on ads in the morning? Are the stats delayed, so I am getting a click dump in the AM? Are daily ad budgets depleted by 6-8 pm and this causes the .03 to .05 clicks?

Anybody noticing this pattern or am I just one of the lucky ones? ;-)

On a somewhat related note, I urge everyone to read this thread in the AdWords section:
[webmasterworld.com...]

In it, you'll discover that - according to AWA (on page 3, I believe) - Google employees are actually encouraged to have their own AdWords accounts, in direct competition with AdWords customers.

Some people on the thread are incredulous and find it a huge conflict of interest. My question - still unanswered - is whether Google employees are encouraged to have AdSense accounts. My thinking is that they are, based on the AdWords revelations.

ASA, care to respond?

I've noticed this trend for a long time as well.

I just attribute it to the highest paying advertisers' daily budget being reached, leaving lower paying ads to display.

I've been experiencing the same thing for at least the last two weeks. Often I get 1/2 of my total earnings in the first 6-8 hours of Googles day. I keep thinking that ahhhh things are turning around again but then disappointment at midnight.

I also notice I'll get a few high CPC clicks on some channels within the first 3-4 hours of the day and then essentially nothing for the rest of the day. The problem with that is I increase my advertising on those channels quickly to capitalize on the increased CPC - then get killed by the end of the day, often giving away money.

Even after increasing my pages/topics by 25% over the last 8 weeks I'm continuing to struggle to make 1/2 of the income I made in may/june.

BTW, has anyone noticed that the higher your daily earnings get the wider the swings between your best and worst days of the week/month?

My earnings were a little more stable with roughly $35 swings from high to low until I made my last site improvement and now my average is way up and earnings are great but the swings from high to low now seem to have $100 in drift which is somewhat distressing.

Do this get worse the higher you go?

I'm not in your league, incrediBill, but I've noticed the opposite. The daily figures are more stable, though there are still some ups and downs. You might want to recalculate this by percentage or ratios, not actual $s, by the way. A swing of $100 when your daily average is a large number might be a smaller swing, in percentage terms, than a swing of $25 when your daily average is a small number.

Percentage wise it appears the gap widened high to low days in the month from 25% to 35% as my earnings increased.
