有很多令人鼓舞的询问new sponsorship/advertising initiative, but everyone wants to know about readership numbers and traffic — which of course is perfectly reasonable.
So, here’s the gist of the traffic this site generates, and how many impressions a sponsor can reasonably expect in a month.
According to my stats from Google AdSense, I averaged a little over 6,000 impressions per day for the last two monthsThis number has been slowly inching higher over the course of the last yearTraffic is generally lower on weekends (especially Sundays) and higher on weekdays.
I think Google’s estimate here is very accurate, and comes very close to the number I come up with analyzing my server logs(No less than Tim Bray agrees regarding谷歌“印象”数量的准确性.) However, this only takes into account my home page and my individual article archives — which were the only pages where I displayed Google’s ads.
我的项目部分- 对于Markdown，SmartyPants等— averaged between 700 to 800 page views per day for the months of August and September to-dateUnlike the Google ads, my sponsorship ads are running on these pages too(They’re running on almost every page of the site in fact.)
So my honest estimate is that my sponsorship ads will average around 7,000 total impressions per dayAssuming I sell out all five slots, each 4-week sponsor should receive about 39,000 impressions:
（（7000页/天）*（28天））/ 5个广告位= 39,200总展示次数
In terms of CPM, that works out to $500/39K, which is roughly $12.75 CPMFor a weekly $200 sponsorship, it’s roughly a nice even $20 CPM. When there are fewer than five active sponsors, those CPM rates come down.
To be clear, the appeal of 万博manbetx贴吧 as an advertising forum is not the raw page view counts — there are scads of sites, including many weblogs, with significantly more traffic万博manbetx贴吧’s format — longer articles posted around twice a week — generates many fewer page views than a weblog consisting of multiple blurbs posted several times per dayThere are other factors to consider as well, such as the fact that I don’t offer comments — a feature that encourages regular readers to reload pages several times per day.
我可以合理估计我服务的页数多少读者that translates into — well, that involves some guesswork. Extrapolating web server logs into readership numbers is right up there with政治选举投票in terms of exemplifying the old “lies, damned lies, and statistics” aphorism[更新：I had originally attributed this quote to Mark Twain, but in factit’s from Benjamin Disraeli, whom Twain in turn quoted in his own autobiography谢谢保罗比尔德为了纠正。]
In a typical 48-hour period after I publish a new article, I serve pages to around 10,000 unique IP addresses: roughly 6,000 for my home page, and 4,000 for individual articles in my archiveThis is far from an exact count of unique读者Some readers access the site from multiple locations (work and home, for example); in other cases, multiple readers are hidden behind a single IP addressBut I think it’s a fair, conservative estimate of 万博manbetx贴吧’s regular, loyal readershipIf anything, I honestly suspect the true number is higher than 10,000 — if for no reason other than that many readers might only check the site once a week or so.
Another way to look at it is to count unique IP addresses accessing my public RSS feedIn the same 48-hour period after I publish a new article, I average a hair over 10,000 unique IP addresses accessing my
/index.xml资源That doesn’t count the 1,272 subscribers reading my feed viaBloglines— a deservedly popular web-based aggregator that only accesses my feed once and shares the data with every Bloglines user who is subscribed to my feed.
Unique IP addresses are easy to count, but again, there are all sorts of reasons I can’t state with certainty how many人are subscribed to my feedSome people might subscribe both from multiple locations (e.g. Bloglines at work, NetNewsWire at home)And because 万博manbetx贴吧 is in the default subscription list for popular Mac aggregators such as NetNewsWire and PulpFiction, there are surely一些subscribers to my feed who aren’t actually regular readers of the site — they simply never bothered to unsubscribe.
The most interesting metric would be how popular 万博manbetx贴吧 is relative to other web sitesBut if estimating readership is guesswork, estimating relative popularity compared to other sites — without access to verifiably-accurate copies of other sites’ server logs — is well-nigh impossible.
Bloglines维护着一个“最受欢迎的博客”列表, ranked in order of how many Bloglines users are subscribed to each feedBecause Bloglines is web-based and thus cross-platform, I suspect their rankings are pretty accurateAt this writing, 万博manbetx贴吧 is ranked 99th. That’s based solely on Bloglines users subscribed to my main
/index.xmlRSS订阅If you added the 140+ Bloglines users who are subscribed to my仅限会员的Feed, the ranking would jump another 10 spots or so.
Now that’s certainly not to claim that 万博manbetx贴吧 is one of the 100 most popular web sites in the world我的意思是，来吧But it strikes me as a fairly accurate gist of where 万博manbetx贴吧 stands in relation to other weblogs — and perhaps more importantly, how popular Daring Fireball is amongst the sort of people who know what a “syndicated XML feed” is.
If humility didn’t stand in the way, I might point out that very few of the sites in Bloglines’ rankings listed ahead of 万博manbetx贴吧 would be appropriate venues for advertisers targeting 万博manbetx贴吧’s savvy Mac-enthusiast audience.
