If you list with a quality directory (most are paid) you will ensure that you get strong back links and indexed pages on SE's which will certainly help in your PR rating here is a good choice for consideration http://www.forplex.com/submit.php Thanks
One of my sites has a PR4 only from free article and directory submissions (in fact bought a link first time for it today from Alang)...but it took a few months to get there. Saves a lot of time if you buy links.
In my view good pr back link from directory and article submissions will certainly increase page rank of that site.
links from directories alone are not going to get you ranked for any difficult searched terms.....I'm not doing SEO to increase PR, I'm doing it for traffic
Looks as if there is some need to get a list of directories to submit to. After visiting this thread this morning, I aske some of the my buddys for some information and until now I recieved the following lists that might be helpful. I had no time to sort the list but I know my friends won't try to cheat, they just sent their experience. This is unsorted and contains free and paid submission directories - some URLs might be duplicated. All seem to pass PR. First a selection of the (well) known: DMOZ - http://dmoz.org/ YAHOO - http://dir.yahoo.com/ GoGuides.org - http://www.goguides.org/ JoeAnt – http://www.joeant.com Zeal (non-commercial) - http://www.zeal.com/ Gimpsy – http://www.gimpsy.org HotRate (must be an editor) – http://www.hotrate.com Xoron - http://www.xoron.com/ Lycos Directory - http://www.lycos.co.uk/dir/ business.com - http://www.business.com/ Canada Proudly Canadian - http://www.porthardybc.ca/ LocalSites.ca - http://www.localsites.ca/ CanadaOne.com - http://www.canadaone.com/ StartPage.ca - http://www.startpage.ca/ UK Limey Search - http://www.limeysearch.co.uk/ dotukdirectory.co.uk - http://www.dotukdirectory.co.uk/ Splut.com - http://www.splut.com/ Australia Ausie.com - http://www.aussie.com.au/ AAA Smart Search - http://www.aaa.com.au/ The Australian Internet Directory - http://www.directory.com.au/ Free (some ask for a reciprocal link) http://www.jayde.com/ http://www.pedsters-planet.co.uk/ http://www.url.biz/ http://www.searchsite.com/ http://www.ectrade.com/ http://www.maxpromo.com/ http://www.searchwarp.com/ http://www.subjex.net/ http://www.websearch.com.au/ http://www.asiadragons.com/ http://www.aesop.com http://www.aewi.com/ Australia, Christian and India Australia Possum Pages - http://www.possumpages.com.au ZEAL, Australia - http://au.zeal.com http://www.imarvel.com/best/web-sites.html http://www.webmasteryp.com/ http://phil.mav.net/ http://search.netpei.com/ http://www.asiadragons.com/ http://rex.skyline.net/ http://sbd.bcentral.com/ http://searchuk.com/ http://www.smartlinks.org/ http://laurel.netster.com/ http://www.webdirectory.com/ http://www.worldhot.com/addurl/ http://search.711.net/ http://www.directory.net/ http://www.bbc.co.uk/ http://www.awebhostingprovider.com/ http://www.beebuzz.com/ http://www.spheri.ca/directory/view.php/ http://www.theknowledgenetwork.org http://www.frequentlyasked.info http://www.spheri.com http://directory.edu411.org http://www.action-learning.com/resources/ http://www.illumirate.com http://fitnesspros.net/search/ http://www.search-2-search.com http://www.seekon.com/ http://www.linkopedia.com/ http://www.onemission.com/d.pl http://listingsca.com/ http://sunsteam.com/ http://www.re-quest.net/ http://www.123world.com/ http://dcpages.ari.net/ http://dcregistry.com/ http://www.fly2net.com/ http://www.joeant.com/ http://www.christianwebsitedirectory.com/ http://www.phatoz.com/ http://www.arielis.com/ http://1st-spot.net/ http://www.giftsbyursula.com/links/pages/ http://01webdirectory.com/ http://www.allwebdirectories.com/ http://www.about.com/ http://www.maven.co.il/ http://www.pharos-search.com/ http://www.josh.nu/ http://wwwomen.com/ http://www.myallfish.com/ http://www.goguides.org/ http://www.asmallbusinessdirectory.com/ http://www.invisible-web.net/ http://www.gimpsy.com/ http://www.canadopedia.com/ http://www.achoo.com/main.asp http://search.jayde.com/cgi-bin/submit.cgi http://submitit.bcentral.com/msnsubmit.htm http://www.home-business-search.com/cgi-bin/add.cgi http://www.turnpike.net/directory.phtml?getentry http://www.zeal.com/ http://www.openhere.com/ http://www.scrubtheweb.com/addurl.html http://www.creativethought.com/ http://www.onemission.com/d.pl http://www.ditto.com/addurl.asp http://www.searchking.com/add_url.htm http://www.searchtheweb.com/suggest/ http://www.surfgopher.com/addurl.htm http://www.dxpnet.com/riot/submit.asp http://www.wowdirectory.com/how_add.php http://www.walhello.com/addlinkgl.html http://www.surfsafely.com/urladd.html http://www.internetb2blist.com/house/submition.asp http://www.peekaboo.net/ http://www.townnet.com/ http://www.galaxy.com/ http://www.enterweb.org/ http://www.superpages.ca/ http://www.imarvel.com/best/web-sites.html Hope this helps to get some links from directories.
I believe that links from quality Directory (Good PR of the Directory and Good PR of that incoming link page, with minimum outgoing links from that page) will really hep to increase th PR. Also the article submission help. Because if your article will get listed on around 300 articles site, then 300 incoming links is not bad amount. Article links will directly help your site to boost the back links and the visitor. Thanks w.s
