Holy crap?! A blog with 50,000 unique pages?... And they're not indexed... Hard for me to believe.

Well, here's what I would be doing. I'd be submitting to Auto Backlink Generator, and Auto Backlink Feed Generator (thank you Karrax), submit to Pingler.com, write 3x300 SEO'd articles on 3stepads.com, writers-block-unblocked.com, and unique-article-database.com, submit my RSS feed to Feedage.com, and Feedest.com, and I've even made YouTube videos.

I don't like articles as they often need to get approved, so they aren't instant and they annoy me... However you could use GoArticles.com and ArticleAlley.com.

Other ways are social bookmarking and stuff, but that's lost its flair for me - Digg used to get me indexed in minutes, but now that's not the case. I recommend SocialMarker.com, or Socialmatic.com. But I highly recommend getting this outsourced unless you have a developed account. And I especially recommend checking out Bookmarking Demon.

I also love to use Twitter - gets spiders on it all the time. I just say something like, "Kris Roxas http://krisroxas.com awesome blog, love it - check it out!"

Blog commenting - leave a link in your name, but really... Do NOT place it in the body of your comment unless it's highly relevant. You'll look like a spammer, and your comment will mean nothing anymore.

Forum posting - this can be a great way to get traffic, and a link. However, having tons of forum posts won't mean you have tons of links. It just means you have lots of links from a particular site, if that makes sense. I'm pretty sure that forums won't have so much power when it comes to linking...

Internal Linking - since you have so many pages it's possible to do mass internal linking. If you use Wordpress then get the Popularity Contest plugin, and have at it. Also try finding a good Related Posts plugin - I can't find one... Keep it less than 100 links per page!

This would be like a whole day of SEO - except maybe that last part. That could take forever O.o

Tell me how it works out!

Nice post Kris!
Easy add here,
Don't forget to submit the pictures in your blog into search engine.
You have to install the SEO plugin and selecting the right keywords. place your keywords as many as possible in the pages of your blog.

I think something is wrong if you have that many pages aren't being indexed.

More backlinks = deeper Google bot and other SE's go. Are you the whole Google Webmaster toolkit and also do you have a on site sitemap?

Is you blog built with wordpress?

If yes, look for this plugin from the WSO - WP Unique
After that, go to Grow links to your WordPress blog automatically! and sign up for a free beta account. Add in your site within the network.

After that, create your RSS feeds and submit it to the RSS directories. A good tool is to use RSS bot to automated that.

Hope this helps.

thats incredibly suprising because i have an autoblog which has its pages indexed within 24 hours each. i've got 1,000+ backlinks to the page which probably has something to do with it

Get your site installed with Google Analytics, verify it with Google Webmaster Tools, Yahoo, BING as well. XML sitemap is a very good way though, it helps Bots/Spiders to crawl it.

Make sure you have proper links to each page so Bots/Spiders can crawl it.


50K unique pages on what kind of contents? Video? Article? Images?
How many days you worked for that?
