It is not just a server issue.
Pages with more content take longer to load. They also (potentially) contain more useful information. Is this a hit on quality websites?
MFA sites load very quick due to the lack of content. What is going to happen with that ?
I could do another 25% if Adsense ads, and thus, the whole page, load quicker.
From a publisher's point of view, it is all about the visitor's experience, the question to ask on this side of the fence is:
From your experience, and if you've optimized pages or changed hosting companies.. Did page load time affect your CTR?
My experience is not very much, and I wouldn't expect it to unless we're talking about shaving off 3 seconds of more on page load time which is astronomical.
So yes, it should affect your overall earnings but on the fringes where pages load too slow or lightning fast, everything in the middle is not worth the effort/money, best optimize for user experience and traffic, AdSense will then follow.
I'd be interested in seeing how Google punishes advertisers whose ads redirect users to a site on a "slow" server.
In my opinion, most of your bottleneck issues with page load time have nothing to do with server speed -- but rather bandwidth limitations.
So if Google uses a barometer (not sure what measurement this could be) to test page load speed, are they using a modem, cable, DSL, or T1 connection while clicking on that link?
Using a cable connection, the page will load faster than a modem connection. Using a T1 connection, the page may load faster than when using a DSL connection.
The slowest thing for my primary site is loading the AdSense and the Google Analytics code. I have no graphics except for a 806kb background gif and a small bookmarking button. The site is database driven, but it doesn't query until someone actually does a search. I have my own webservers, and connection, and they are very fast. What slows it up every time is Google.
Be interesting to see how much better it might do if GOOGLE sped up their servers...
I can understand Google's point and I can also understand that a lot of page loading time issues are out of the advertiser's hands.
But if this results in a decline in people loading up pages with lots of decorative bells and whistles, this may not be a bad thing.
"I have no graphics except for a 806kb background gif"
netmeg, I'm not sure if that was a typo? 806kb for a background is HUGE? That's like saying you don't have a pet, apart from that elephant over there.
I've experienced a slight increase in my adsense revenue since upgrading to a faster server. It makes sense that faster load times might inprove revenue, but only because it improves the user experience and means they don't click away before the site loads.
I just got off shared hosting and went with a dedicated server about 3 weeks ago. Lightning fast but I've seen no increase in earnings.
Interesting concept though...

Yep, typo. It's 806 bytes.
I fixed a problem with my server (db query against a large table that wasn't indexed properly) that was causing page load times to be measured in the 1.5 minute range once the visitor count went over a certain threshold..
Since then, we're down to the sub-ten second range, and eCPM has increased along with CPC. I made other changes around that time, so it's hard to know what made the difference, but stats were dropping steadily up till the time I fixed the problem.
Profile your sites, definitely.
I recently designed my own in-house page caching system to help speed things up. Now I serve up cached pages for my most commonly requested scripts to anonymous visitors (80% of my traffic).
It has done wonders for the performance of my site, and lightened the load on my single dedicated server. Gave me more time before I need to go to a dual-server setup... and I have no doubt it has helped me achieve better revenue since users seem to be sticking around more/longer (more pageviews per visit).
netmeg, you said my point exactly!
I'm taking analytics off for that reason and the few pages I got adsense, it is the slowest thing on the page. I wish they would bring their response time back to what it used to be.
I have removed Analytics about six weeks ago and have seen an instant increase of about 8% in visitors in my AwStats statistics since then. There is too much variation in the AdSense revenues to be sure that this also caused higher income, but Analytics caused about 60% of the total page load time.
It is a disappointing task to optimize sites, use underloaded dedicated servers on 100 mbit outlets, compress pages on the fly, put expire headers on almost all static content and then conclude that the page load time is mainly determined by an external third party who used to have the fastest internet services in the world, but can't cope with the load today.
As a side note, I don't look at my weekly/monthly stats of AdSense on a regular base anymore because they take too much time to load. It seems Google has some serious performance problems in the AdSense backoffice.

LOL! I'm not jumping in on this discussion, but that's pretty funny.
I want to know:
Is Google reducing payments / penalising slow loading publisher pages?
What metric is used (time to first content render? time to full render? ...)
|Is Google reducing payments / penalising slow loading publisher pages? |
Good question. Maybe some day a high ranking goog tech will defect and violate his confidentiality agreement and spill the beans about all the neat little secrets they have. He'll get assassinated the next day, of course, shot down on a street corner by goog hitmen.
I think the main penalty in slow pages is that, bluntly stated, it pisses your visitors off and they go elsewhere. Visitors leaving a site means less opportunity to put an ad in front of them that they'll find interesting.
Whether google has this factored into their prices, again it's anyone's guess but I'm guessing they don't.
For me the important metric is time to full render. First bytes in browser was a common measurement in dial-up times when people were used to 15 seconds or longer waiting for full render, but nowadays with broadband connections everyone expects a quick response of the whole site.

Hey, that's my comment! I was planning on compiling the data and starting a thread when I got back from vacation. I get back tonight, so I'll post some statistics tomorrow.
It should be noted that a faster server and a faster connection not only boosts CPM and pageviews, but also rankings. I'll post more tomorrow...

If you're comparing Analytics against AwStats, there could very well be an 8% difference in the way a unique user is calculated.
Since we moved to .NET a few years ago, we've implemented their output caching and page loads went from 2-3 seconds to under 1 second. We also enabled gzip, even on our dynamic content, and that helped page load even more, especially for our really long pages.
However, ad placement changed when we upgraded the site to .NET so it is tough to define exactly what caused the increase in AdSense revenue, but it did increase significantly and I wouldn't say the ad placement changed a ton.
hope you`ve had a splendid vacation. What would you say is a reasonable size in terms of KB to make Lord Google Engeneers happy after their latest algo modification ?

The Google servers cause slow loading far more than anything else on my sites. That is especially true with Google Checkout (not with Adsense, IMO). The Checkout images in particular are slow loading and sometimes load so s-l-o-w-l-y they actually can make my websites hang and even cause a reboot when they hang forever at times!
P.S. I have never seen a delay with AWstats.
I hope it's much much less than 10 seconds.

Site speed is something I believe in. Moved from a rubbish host (the biggest rubbish host in the UK - yeah that one) to a decent one many years ago and did notice the traffic start growing once again. That would easily have given me the 25%.
Though recently I moved to a dedicated server at vast expense. It's probably the most underused dedicated on the planet. No abnormal increase in traffic after 5 weeks.
Still, would have had to do it next year anyway and I'm not moving back - a good site speed is a solid base for furure growth. Nothing more annoying to visitors than a slow site.
Page load times can be affected by the ad itself, as well. Especially now that Google will be serving ads with that set cookies and contain web beacons. Those events are out of the publisher's control, but they're capable of slowing down the display. At least the display of the ad. I'm not sure if it can slow down the whole page.
|Faster server, faster connection, income up about 25% |
Not from where I am standing.
I moved to a dedicated server. The clicks are about 20% more per day, but earnings are down.
FWIW, I spoke to Google today. They claim their Fortune 1000 customers are not affected by any slowness so anything below that traffic level shouldn't be affected...
doesn't it also make sense the other way around?
as publisher, if you have slow loading pages, you increase the chance that someone clicks on an ad, provided that a) he's already on your website and b) the ads are displaying as long as possible while loading the next page. may be the visitor is less interested in your ads than in your content, but why not take advantage of his impatience. it's about programming technique..
