I've had a Wordpress blog at Mydaytradingtutor.com/news/ since Nov 2006. Since that time, I was pretty active posting. When I was actively posting, the posts would get indexed instantly. That went on until April 2007 when I stopped posting. I started posting again on July 2008. Now two people actively post on the blog. For a while, the posts wouldn't get indexed. I then upgraded the Wordpress version this year and they started getting indexed again. It got to the point where the posts were getting indexed instantly on blogsearch.google.com (where I normally search for them after posting). Then, all of the sudden (on about Oct 2008 ), the pattern stopped. Some posts got indexed days later (both on blogsearch.google.com and Google). Some never got indexed, so they still don't even show up on blogsearch.google.com or google when I do a search for the post URL. I'm totally baffled by this. Could it be that I need to change the URL list on Wordpress' "Updated Services;" i.e., the list of URL's that Wordpress is supposed to ping every time you post? This is the list I currently have since 12/6/08: http://rpc.pingomatic.com http://1470.net/api/ping http://www.a2b.cc/setloc/bp.a2b http://api.feedster.com/ping http://api.moreover.com/RPC2 http://api.moreover.com/ping http://api.my.yahoo.com/RPC2 http://api.my.yahoo.com/rss/ping http://www.bitacoles.net/ping.php http://bitacoras.net/ping http://blogbot.dk/io/xml-rpc.php http://blogdb.jp/xmlrpc http://www.blogdigger.com/RPC2 http://blogmatcher.com/u.php http://www.blogoole.com/ping/ http://www.blogoon.net/ping/ http://www.blogpeople.net/servlet/weblogUpdates http://www.blogroots.com/tb_populi.blog?id=1 http://www.blogshares.com/rpc.php http://www.blogsnow.com/ping http://www.blogstreet.com/xrbin/xmlrpc.cgi http://blog.goo.ne.jp/XMLRPC http://bulkfeeds.net/rpc http://www.catapings.com/ping.php http://coreblog.org/ping/ http://www.lasermemory.com/lsrpc/ http://mod-pubsub.org/kn_apps/blogchatt http://www.mod-pubsub.org/kn_apps/blogchatter/ping.php http://www.newsisfree.com/xmlrpctest.php http://ping.amagle.com/ http://ping.bitacoras.com http://ping.blo.gs/ http://ping.bloggers.jp/rpc/ http://ping.blogmura.jp/rpc/ http://ping.cocolog-nifty.com/xmlrpc http://ping.exblog.jp/xmlrpc http://ping.feedburner.com http://ping.myblog.jp http://ping.rootblog.com/rpc.php http://ping.syndic8.com/xmlrpc.php http://ping.weblogalot.com/rpc.php http://ping.weblogs.se/ http://www.popdex.com/addsite.php http://rcs.datashed.net/RPC2/ http://rpc.blogrolling.com/pinger/ http://1470.net/api/ping http://www.a2b.cc/setloc/bp.a2b http://api.feedster.com/ping http://rpc.technorati.com/rpc/ping http://rpc.weblogs.com/RPC2 http://www.snipsnap.org/RPC2 http://trackback.bakeinu.jp/bakeping.php http://topicexchange.com/RPC2 http://www.weblogues.com/RPC/ http://xping.pubsub.com/ping/ http://xmlrpc.blogg.de/ http://rpc.newsgator.com/ http://xping.pubsub.com/ping/ http://www.snipsnap.org/RPC2 http://www.rssfwd.com/xmlrpc/api http://www.newsisfree.com/RPCCloud http://www.imblogs.net/ping/ http://www.holycowdude.com/rpc/ping/ http://signup.alerts.msn.com/alerts-PREP/submitPingExtended.doz http://services.newsgator.com/ngws/xmlrpcping.aspx http://rpc.wpkeys.com/ http://rpc.weblogs.com/RPC2 http://rpc.tailrank.com/feedburner/RPC2 http://rpc.icerocket.com:10080/ http://rpc.britblog.com/ http://rpc.blogbuzzmachine.com/RPC2 http://ping.blogg.de/ http://pingqueue.com/rpc/ http://pinger.blogflux.com/rpc/ https://phobos.apple.com/WebObjects/MZFinance.woa/wa/pingPodcast http://bblog.com/ping.php http://api.feedster.com/ping.php This is the list I had prior to 12/6/08: http://rpc.pingomatic.com http://www.blogpeople.net/servlet/weblogUpdates http://bulkfeeds.net/rpc http://ping.myblog.jp http://ping.bloggers.jp/rpc/ http://bblog.com/ping.php http://www.bloglines.com/ping Totally confused about this.
