Google Indexing In Near-Realtime 79

krou writes "ReadWriteWeb is covering Google's embrace of a system that would enable any Web publisher to 'automatically submit new content to Google for indexing within seconds of that content being published.' Google's Brett Slatkin is lead developer of PuSH, or PubSubHubbub, a real-time syndication protocol based on ATOM, where 'a publisher tells the world about a Hub that it will notify every time new content is published.' Subscribers then wait for the hub to notify them of the new content. Says RWW: 'If Google can implement an Indexing by PuSH program, it would ask every website to implement the technology and declare which Hub they push to at the top of each document, just like they declare where the RSS feeds they publish can be found. Then Google would subscribe to those PuSH feeds to discover new content when it's published. PuSH wouldn't likely replace crawling, in fact a crawl would be needed to discover PuSH feeds to subscribe to, but the real-time format would be used to augment Google's existing index.' PuSH is an open protocol, and Slatkin says that 'I am being told by my engineering bosses to openly promote this open approach even to our competitors.'"

    ...someone help me out here. People can still find my articles through google before I see the googlebot hit any new articles I post...how is that possible? How would my pages show up on google before the bot actually crawls them?

      My site is by no means something high traffic but Googlebot indexes my pages (and shows them in search results) within three minutes:

        Absolutely. With this breakthrough technology, a cutting-edge new media purveyor can ensure that their reportage, opinions and commentary are easily accessible to the general public with a minimal delay. In today's fast-paced Internet, a few minutes' delay can make the difference between being on the breaking edge of news and being an Johnny-come-lately.

          As you write more often (say on a specific time schedule and daily) the people who don't read via RSS (which in my case is the majority of my readers) will learn to make going to your site a part of their daily routine and thus your visits on new material will go up.

            I watched visiting trends, by hour, over the last two years in Google Analytics and picked 7:30 AM and 10:30 AM as the times to post material. It seemed as if most people were checking once in the morning when they got to the office and once at breaktime/lunchtime around 11 AM. To account for some of the time variance seen across those two years I went with 15 minutes earlier than the stats showed. Seems to work for me.

      • I've noticed that when I post a new blog entry on Livejournal, it appears in Google's results within 2-3 minutes. I know that Livejournal has a public feed for all new blog entries across the site, so I assume Google must be indexing this (and presumably others).

    If google notices your site/blog updates frequently the bot will come around more often and especially if its a high page rank site.

        1. Go to 4chan/b and post a unique sentence.

        RSS is a pull technology. I update my blog, which updates my RSS feed and the googlebot goes out and pulls my sitemap (which is my RSS feed on Blogger) and indexes any new pages. This technology sounds like I can ping Google when my site is updated and they can know there is new data for them to pull.

        • No, this is not a ping technology. The hub actually sends the new data to the recipient. So basically you publish a feed. The hub subscribes to that feed. When you post new content, you ping the hub. The hub then fetches the new data. It then turns around and sends the new data to anyone who's subscribed to the hub. So it saves on two fronts. First, there's no polling of anything anymore (since you tell the hub when it's updated, and the hub sends out the new data when it has it). Second, the load
      • RSS is pull technology, so the interested server (ie Google) needs to keep polling you asking if you have new content.

        PubSubHubbub is push technology. So when you make a change, you submit it to a hub which in turn knows the interested parties that have asked to know about your site and then distributes it to them.

        So it is more efficient since there isn't a constant polling and it is faster since there isn't a poll lag.
    • Yes, a good site map, lists the last changed date for each page. Google reads the site map for each site first. So the above Author is right the PUSH system is already integrated into sitemaps in the last Modified and changed attributes, and no new protocols or hubs systems are needed.

It was in the index by March 3, 2010 5:08 PM. And it was not even from news.google.com, it is the general web search.

Simply having a battery operated bar code scanner next to the garbage can, so that we can scan what we toss, (things that we want to restock) is enough.

That is basically the important functionality. You can jazzit up by making the scanner really small and portable and you can carry it to the stor

        This is a very fantastic idea. I would love to have something like this as, when I typically go to the grocery store, I find myself buying the same stinking food again and again (it's tough to have a good imagination when you're in a rush).

  • Amusingly, since this is based on Atom, the client still has to poll. It just has to poll fewer sources. The connection between the original source and the "pushsubhub" server really is a "push" connection, but the hub to client connection is not.

    Also, the "pushsubhub" caches and redistributes the feeds, which means the feed operator no longer sees their own clients.

    They don't seem to have addressed the general RSS problem of "server timestamp/ID changed, but content did not". Some RSS feeds get this

        You're right. Which implies that the subscriber has to have a web server. Somebody will probably try a "web server in the browser" thing for browser-type subscribers.

  • Seems to me that push-publishing already is implemented on the web via services like Ping-o-Matic [pingomatic.com] and such. I can't see why a new push-publishing method would be needed since the blog ping works elegantly. Obviously, the system is abused by spammers, but Google's solution would suffer from the same problem too.

Technology is dominated by those who manage what they do not understand.
