Blocking advertisers versus not blocking advertisers is not a simple answer - really depends on your site. I manage 2 sites, and for 1 it doesn't seem to make a difference because it's super high volume and low CTR. But my other site is very content specific and I know that ads unrelated to the content will NOT receive clicks - so I block a TON of advertisers and it definitely helps with earnings. Sure the more advertisers in theory raises the CPC prices, but you don't need every Adwords advertisers to reach the max CPC. If you went overboard with blocking it probably would hurt your site earnings, but personally I know that blocking advertisers that have no relevance to my content is best for me. Assuming Google's systems are working - which is in question currently.
blocking ads works well for a market with low competition among the advertisers, because the low competition lets the "creepy ads" in ...this is my case I am constantly doing this, but unfortunately I have reached the limit of 500 blocked advertisers... some of them were included a long time ago and maybe they are not live anymore... but I am still too scared to reset the list and start from scratch ...
netmeg, this is exactly what I am planning to do ... maybe it will worth to try build the ignore list again, because some of the sites that I currently block probably are not active anymore... so I have to clean the list somehow...
The only advertisers I block are the ads that are simply garbage ads, regardless of who is seeing them. Some ads, although not many, simply have no value.
Aside from this, I once again contacted Google directly (second time in 3 months) about my poor earnings with steady to increased traffic (three sites). I'm hoping for more than the last response, then reply. They consisted of the canned optimization response, then the "try asynchronous due to increased mobile views" which is less than 10% for my sites. Then she basically ended with "...otherwise, I can't see a reason".
My worst day ever, earnings have completely stopped and after 12 hours I have still yet to get one click from the USA, the UK's thrashing the US by 2-0 !.!.!
My EPC today is 10% of average, pathetic does not begin to describe my feelings at the moment, if things have not picked up within 24 hours AdSense will be disappearing, it's like being on a sinking ship.
And I do not want the excuse of a US holiday on Monday as a reason, previous years have never, ever had this effect, for me AdSense has been banjaxed since the start of this year and simply been getting worse every day.
Same thing happened to me today. First time ever that USA was not the top country. USA clicks pitifully low today. I don't understand why my Adsense pageviews are down considerably when Analytics shows my traffic has not changed.
A few days ago I also released the 100+ advertiser urls I had blocked. Now down to about 15. So far no change, but I'll give it a couple weeks, probably needed to be cleaned out anyway.
CTR has improved to the normal average the last 2 days, but the CPC and RPM is still quite low compared to most months. Also still seeing garbage advertisers that I've never seen before the last 3-4 days.
The working day's stats haven't made sense since Xmas, nothing seems to be correct until the day is completed now. Whereas the last few days I've been seeing no clicks from the USA until overnight, I've already got a couple of US clicks for $3.00+ yet, supposedly, I have hardly had any visitors from the UK nor any clicks.
Well G, I can see more genuine UK visitors on my sites at this very moment than you're reporting Page Views so far today...and that would be 22 pages! Yeah, right . . .
I found my CTR returned to normal monday. Very odd how all of a sudden it rebounds. Wonder if google changed their filtering algorithm...I should really start tracking actual clicks on the ads to see if google is filtering clicks.
Monday nearly returned to pre-Xmas daily clicks average but with an EPC at 87%.
Overall a very significant, further and extremely disappointing reduction in earnings at 47.4% compared to January 2013.
The damage caused by Google's image grab of 28th January 2013 can now easily be seen with Page Views at 42.3%. With the daily deterioration of the SERPs and Image Results, I feel it is only a matter of when, not if, we remove AdSense altogether from most of the smaller sites.
All new sites and those being updated to html5 are being launched without any form of advertising however the decision of what to do with our five largest properties has yet to be taken.
Our main site (to date this year) has currently produced 8.5 times the Adsense revenue it did all of last January. We're on pace for it to be between 10 and 12 times last January's revenue by the end of the month. Today is slow but yesterday was killer. We'll see how it goes but Adsense is working for us at the moment.
On a side note, we've seen a nice boost in organic traffic from G over the last couple of days as well. Sometimes just leaving things alone for awhile is the best policy.
CPC prices still very low. That said, I have seen an increase in clicks from outside the U.S. which is lowering my average CPC and RPM. I'm also concerned about these outside the U.S. clicks and what I can/should do.
wow this is really weird! :) yesterday I have blocked an advertiser URL, because the ads were irrelevant and miracle ... today in "Ads (Ad review center)" I can see all their ads ... to me this is clear indicator, that G do not know what they do! Another thing that I observe since the beginning of this week. My timezone setting is GMT+1 and a have decent traffic (mostly US). Analytics show stable traffic all day long and I have no clicks at all, but ... some time after 24:00, obviously they recalculate something and then the clicks appear ... well this is also weird, because there is normally to be a lag in the "real time" monitoring, but I think that there is something more... anyone have the same or similar observations?
