Pligg evolved from code from the site mename. It allows you to make a site similar to Digg where users can rate web pages. However, Pligg can be used for almost any type of article web site. Customizing the templates and getting your site customized has proven to be a chore for many of its users though.

Pros: Very flexible. Simple to edit and learn.
Cons: Low on features. Hard to find templates or modules.

My pligg site: Slovenian digg

Update to 9.9.5. Its first SEO friendly version of pligg cms system.

Keywords
Put your top keywords into tags & categories!

Participate! Don't just submit your own links and then disappear. I know I'm guilty of this myself at a few places, but it really is in your best interest to get involved with these bookmarking communities that have relevant themes and niches. Popular members can get high PR profiles, and people are more likely to check out your articles and links. Of course, the key to any successful submission is that the content fits the need of the group. It is a democracy after all, and any good SEO needs to keep that in mind when working with web 2.0.

Download & install: http://patchlog.com/wp-content/uploads/2008/04/xml_sitemaps-0.9.zip

After installation you should be able to access the sitemap index like this : http://yourdomain.com/module.php?module=xml_sitemaps_show_sitemap or if you want the sitemap to look friendly ( btw ask.com will only accept a friendly sitemap ending in .xml ) , you just have to go into Admin->Configuration->XmlSitemaps and enable "Sitemap Friendly URL", and if you do that then you have to put the following lines in your .htaccess somewhere before the line "##### URL Method 2 ("Clean" URLs) Begin #####" :

RewriteRule ^sitemapindex.xml module.php?module=xml_sitemaps_show_sitemap [L]
RewriteRule ^sitemap-([a-zA-Z0-9]+).xml module.php?module=xml_sitemaps_show_sitemap&i=$1 [L]

After that put the following line into robots.txt:
Sitemap: http://www.yourdomain.com/sitemapindex.xml

Submit your sitemap to:
Google: http://www.google.com/webmasters/
Yahoo: http://siteexplorer.search.yahoo.com/
MSN: http://webmaster.live.com/

This release addresses a security issue discovered by Secunia Research. We thank Secunia for alerting us of the problem. At the same time we apologize to Pligg users who might have to make a second upgrade after the recent 1.1.0 release. The good news is that the upgrade process from 1.1.0 to 1.1.1 is very simple.

The 1.1.1 version fixes a couple issues that were discovered in the previous 1.1.0 release, in particular a fix for RSS feeds, and a bug that caused sites to show blank pages after a successful installation.

One modification recently made is that the "Top Users" page will now sort users by karma score in descending order. Previously this page displayed all users and sorted them by username in ascending order. The page will now hide any users with a karma score of 0 or below (negative karma), punishing inactive users. In order for your site to benefit from this change you must run the /libs/karma.php file using a cron job, or your web browser, regularly.
