Must have seo plugins for wordpress??

Below are the Plugins that I use for all my Wordpress sites, can't live without them. You just need to go to the plugins section and search for them. You'll find most of these in the 'popular' tab.

- All in One SEO
- Google Analyticator
- Easy AdSense
- XML Sitemaps
- Sociable
- WP Cache

You also need to ensure that you change your permlinks so that your URLs look static and not dynamic;

Under Setting > Permlinks type in %postname%.html. You don't really need anything else other than good content.

Hope that helps

I understand the point of your question, but I would be cautious about loading up your sites with plugins without a specific purpose.

Personally, I only use two plugins for every niche adsense site I create, Google XML Sitemaps and my own ClickBump JumpStart.

Google XML Sitemaps allows me to easily create and publish my sitemap.xml file for Google's webmaster tools.

JumpStart allows me to instantly create my default pages (about, contact, privacy and main post page) as well as setting up all my theme options so that I don't have to manually enter them.

Database backup, captcha and All in One SEO are my absolute critical plugins. I use wordpress almost exclusively and these are installed on all 50+ WP sites I have. Please don't forget to backup, I've lost a couple sites before I started backing up due to hacks and its a horrible feeling, and one of those things you always "mean to do" but never get around to until its possibly too late!

All in One Seo
WP-Backup
Google XML Sitemap generator - activate this after you are done posting your first article, you dont want the googlebot on your empty site(it just prolongs the indexing time-as per my personal experience)
Easy-Install (For webmasters)
Easy-Analytics (For Google Analytics)
GoCodes (To cloak affiliate links) Although I am looking for a better plugin to track the outgoing links
WP-Crumbs (To get the crumbs linking structure as mentioned by google in their seo doc)
Yet another related posts plugin - really helps your internal linking - once you get many posts going
Easy-Contact --> Set up your Contact page in an instant(Contact pages are appreciated by google)
Privacy-Policy Plugin --> You can modify the source code if you want to make any changes ,if you are planning on setting up mass sites. Privacy Policy is something that google appreciates.
