Hey guys - I found this forum a few weeks back and have been reading and digesting the content. It's great ! Apologies for making my first post a question; I have read as much as I can to try and find an answer... I don't have adsense, I haven't signed up - I'm just trying to learn so I can build around what I know. With regards to the topic of the ads, how dynamic is this? I mean if the site is dynamic, and the content of my index.php with a high frequency, would adsense adjust to this? I read you can specify a certain block of words for google to use for ad content - but is this picked up immediately? For instance, if my site used an RSS feed that spewed out a story every few seconds, and index.php only showed the latest story, would the ads be story relevant ? If I haven't explained this very well, please ask me to elaborate !! Thanks, ben
The AdSense crawler revisits your site at irregular intervals, yes, but probably not quickly enough for what you'd like to do. On a truly dynamic page you can expect to see irrelevant ads unless there's a general topic that runs throughout all the content. For example, if you had a news site about cellphones then you'd see relevant ads. If you had truly random news, though, expect truly random ads! For AdSense to work best you need to have well-targeted pages.
I'm surprised how fast the ads become relevent after I post a new page. I posted a blog comment about silk screening and within 3 hours it was offering silk screening equipment. One thing I've noticed is that if your site is topical, the ads it'll throw up on new pages is often very tied in with previous pages -- so it will generally be on topic.
Actually, I should have pointed out that blogs get scanned more often by most crawlers in general, including the AdSense crawler.
I actually have a search engine that can produce millions of different dynamic pages according to what the user enters into the search box. Google seems to do very well "reading the page" instantly and producing "not bad" results. Now here is the wierd part(and only what I theorize)--If the page gets visited only once works great. But if it is a popular search phrase like "paris hilton" then for a day or two, until the crawlers visit, the Relevancy and amount per click seem to drop off.
That's different. An URL with different query parameters is treated as a separate URL by AdSense. And since the keywords are in the query parameters, you'll get well-targeted results right off the bat in most cases.
interesting how changing your ip (country ip) with proxy servers significantly changes relevance of ads displayed, that's mine experience.
That's because the available ad pool to select ads from can vary considerably from country to country. AdSense publishers should always have a firm understanding of AdWords.
