Faster server, faster connection, income up about 25%.
How did you come to the conclusion your site was slow? Visitor complaints?
By the way, recently in the AdWords Blog [adwords.blogspot.com], Google said something which indicates it is finally understanding the significance of slow servers to its profits.
Landing page load time will soon be incorporated into Quality Score... As part of our continuing efforts to improve the user experience, we will soon incorporate an additional factor into Quality Score: landing page load time. Load time is the amount of time it takes for a user to see the landing page after clicking an ad. . . . Why are we doing this? Two reasons: first, users have the best experience when they don't have to wait a long time for landing pages to load. Interstitial pages, multiple redirects, excessively slow servers . . . users are more likely to abandon landing pages that load slowly, which can hurt your conversion rate. . . . In the next few weeks, we will add load time evaluations to the Keyword Analysis page (we'll notify you when they are available). . . After the one month review period, this load time factor will be incorporated into your keywords' Quality Scores. Keywords with landing pages that load very slowly may get lower Quality Scores (and thus higher minimum bids). Conversely, keywords with landing pages that load very quickly may get higher Quality Scores and lower minimum bids.
I have never seen anything from Adsense about making sure pages load fast enough. Google says it's going to punish advertisers whose landing pages are too slow. But what about publishers? How much money is Google losing by poor servers? Millions?
How fast is fast? Are shorter pages the equivalent of a faster server? How much faster are your new servers?
I hate to bother with server changes if it's not going to help. But the 25% income boost is intriguing.
How do you know you couldn't make another 25% with even faster servers?
What are the internet industry standard server performance tests?
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.
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.
Be interesting to see how much better it might do if GOOGLE sped up their servers...
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.
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.
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).
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.
Is Google reducing payments / penalising slow loading publisher pages?
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.
Faster server, faster connection, income up about 25%.
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...
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.
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.
If you're comparing Analytics against AwStats, there could very well be an 8% difference in the way a unique user is calculated.
P.S. I have never seen a delay with AWstats.
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.
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..
