Best SEO tools - Post yours
 

Let's keep this an ongoing thread with good SEO tools to help the budding and advanced SEOer.

Show Pagerank - Shows pagerank over different Google datacenters.

Unique backlink checker - Displays domain backlinks. I find it very useful as it doesn't show all the (unnecessary) individual pages that are indexed as a backlink.

Google/Yahoo Rank Checker - Sometimes is off by 1 or 2 positions, but is fairly accurate.

Broken Link Checker - Search engines like it if your site isn't filled with broken links.

McDar's Keyword Analysis - Displays the PR/backlinks/pages of the top 10 SERP listings.

PRSearch.net - Great site with tools for checking rankings, and link pop (without img verification).

Nice Links Joe! |thumb

Here is one I like just to get an idea of keywords and frequency.

The Keyword selector tool.

checking rankings on Google

I got this one from DD several months ago, and I still use it regularly:

tools to check link pop, page saturation and keyword placement (first three SERPS only) across several major engines. I love it. :)

Sandbox Detection Tool - Good tool to check if your site is currently in the Google sandbox.

Hey Joe, link's not working...can you check the URL? I'd love to have that tool in my toolbox :)

The sandbox detection tool one?

It works for me. |huh

woops! wrong thread

Hmmm...must've been something on my end. I tried several times yesterday but now it works. Ahhh, the many wonders of technology :D

http://www.webconfs.com/similar-page-checker.php - Duplicate content tool.

Useful to see if your site may be falling victim to the Google duplicate content filter which totally blew many sites outta the water during Feb update. Apparently a duplicate rating of 75 - 80% is pretty bad news for your SEP's.

In addition, here's a tool I find helpful that does something similar to the tool above, but searches Google for duplicates:

damn this thread is nice... thanks for the tools guys |thumb and keep 'em coming :D I don't have any great tools to contribute, but some newbies might like overtures keyword suggestion tool

Here are a few more tools:

http://web-sniffer.net/ - Best search engine simulator tool I've seen (useful for peeking at cloaked pages ;))

http://www.webhosting.info/ - Not only a domain WHOIS, but also a reverse IP tool (looks for websites hosted on the same IP).

Although the Overture tool is good, here's a better one: http://www.123promotion.co.uk/ppc/index.php

Yahoo Tracker - Makes use of the new Yahoo API that tracks your search engine keyword rankings for various keywords and URLs over time.

NICE!!!! thanks Joe |thumb

Auto Submit - Free auto submit to about 30 SEs

A couple more golden SEO tools I found recently:

Google Link Popularity Analysis Tool - Very-detailed link popularity tool that analyzes your backlinks (including their IP, pagerank, and number of incoming links), as well as a nifty backlink analysis tool.

Google PR Lookup - Bulk PR lookup tool which features a "real" pagerank tool (supposedly uses Google XML to retrieve the "real" pagerank, and not the visual toolbar PR bar).

MSN & Yahoo Keyword Tracker - I've seen a couple Yahoo trackers, but the MSN tracker is a new one.

Thanks Joe! Some good tools. Nice to finnally see some tracking for yahoo.

The PR tool would be nice to double check PR's before trading, catch cheaters.
