Link Analysis Tool : The ultimate open source SEO tool

Backlink analysis is a trick business and can be quite resource hungry. That’s why I’ve started developing an open source Link Analysis Tool.

The tool is currently in Beta and you can download it here. My idea is that by releasing this as an open source project other programmers and skilled people can help me improve the tool based on feature requests and bug reports from the community.

The script has an auto installer to set up the Mysql databases, you will need a Yahoo API – details are in the readme. Please leave feedback and feature requests in the comments below, if any PHP programmers want to contribute then drop me an email.

What it does

  • Uses Yahoo Site Explorer to find all pages on a site
  • Pulls in link data for every page on the site & orders results by pages with the most links
  • Allows you to drill down 2 levels deep into the link data for pages linking to the target site
  • Accepts Google sitemaps imports
  • Accepts single URL imports
  • Lets you check the rankings for any page on any search engine

Example: I enter my competitors url and the tool brings up a list of all their pages with the most linked pages at the top of the list. I can then drill down to find not only the exact sites linking to these pages but the sites that link to the linking pages as well. This allows me to very quickly evaluate the most valuable links to target for myself.

Licensing

You can distribute the script as you wish in any form (for example with your own branding), all I ask is that you leave the “About this tool” link on the right hand side of each page and the designers link at the bottom. Selling the script is not permitted.

    Sweet! I can really use that. Not much more I can say.

    • http://www.yargon.nl/ Karel Geenen

      Does this one still works? I can’t seem to install it anymore…

  • http://www.xuru.com Jeremy Luebke

    The only thing it is missing in a log analyzer so it can daily parse the logs for all referring URLs and then check those pages for links back to the page showing the entry.

    In this way it starts to auto discover the links since Yahoo only shows a small subset of links once you get to a certain number.

  • http://www.pchangout.com PC Forums

    Now that’s hot! I’m gonna download this and give it a whirl.

    The feature I’m excited about is google sitemaps import. Daddy like!

  • http://www.wowjoomla.com azzam

    Why thats mighty noble of you patrick.
    Will take a spin and see if any coding can be applied to improve.

    Patrick – this is a seriously useful tool! Thanks for sharing.

    I really appreciate the great tool, I’ll try to contribute to it as much as possible.

    Hi,

    Thanks for this.
    But I’m getting this error message.

    Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /linkanalysis/index.php on line 45

    What could I have done wrong?

    Thanks for your help.

    • http://www.blogstorm.co.uk Patrick Altoft

      Not sure, have you looked in phpmyadmin to see if the databases are set up?

  • http://carl-johan.hunefalk.com/ Carl-Johan Hunefalk

    Hi,

    Seems like a really useful tool, but I get zero (0) links for any url on any website I test with. Even though there are some results when I try Yahoo’s site. (?)

    Thanks for your help.

    • http://www.blogstorm.co.uk Patrick Altoft

      Maybe your host isn’t allowing the connection to Yahoo?

  • http://www.love-astrology.com Rebecca

    Thanks for the great tool Patrick. Can’t wait to get it installed and analysing!

  • Gemme

    Seems like a great tool, thanks a lot. Am playing with it now.

    I don’t see yet the PR in my overview, am I missing something?

    • http://www.blogstorm.co.uk Patrick Altoft

      Are you seeing PR0 or what? Can you post a screenshot?

  • martaay

    I also get this error message appearing in the error log after trying to add a site through addsite.php

  • http://www.randomkitty.net G

    You can’t downplay the completely invaluable nature of this tool for evaluating your OWN website, to figure out how relevant your linking neighborhood is, etc.

    I’m pretty stoked to get a real clear picture of where my site is at. (And maybe then I can get some insight on the kind of Twitter followers I’ve been attracting, too!)

  • http://www.corysessions.com/ Cory Sessions

    It’s up and running great. I have been looking for a way to see which pages of my sites are getting links. This really helps a lot.

    Thanks for sharing this. Excellent link analysis tool!

  • http://www.marketappeal.co.uk/ SEO-Alchemist

    How will your software compare to SEO SpyGlass?

    • http://www.blogstorm.co.uk Patrick Altoft

      I’m not sure, never used SpyGlass.

  • Del

    Looking good so far. I to am unable to see the PR column. It’s missing from the list of domains on the home page and also the link analysis of the website.

    FYI On the first pass it didn’t capture the number of links correctly – in fact it returned everything as 0 – the same as Carl-Johan above. I refreshed one entry manually and it then displayed link numbers so I refreshed the entire domain and the correct link numbers were displayed. :)

    • http://www.blogstorm.co.uk Patrick Altoft

      Maybe the path to your PageRank images is broken? Can you see in the source code of the page where they are loading from?

  • http://www.seopractices.com SEO Blog

    Hi Patrick, thanks for this great tool. I came to your site from the SEO Book forums, great information there.

  • http://www.seoguru.nl AlainS

    Thanks very much for the tool! But the same information is already given in Google Webmaster Central or am I missing something?

    What I would love to find is a tool that also shows the anchortexts of the inbounds. Not a simple list of all anchortexts, but a statistical overview of all anchors:
    70% anchortext1
    8% anchortext2
    etc.

    Is there something like that out there?

    Thanks again,
    Alain

    • http://www.blogstorm.co.uk Patrick Altoft

      Google doesn’t let you see your competitors backlink information.

  • http://www.ppclab.com PPClab

    I’m getting this message
    Spider results
    http://www.mydomain.com being spidered………
    Cannot connect to Yahoo, you might have used more than 5000 queries today?

    anything i should check…its a new api key

    • http://www.blogstorm.co.uk Patrick Altoft

      Yahoo is quite unreliable, try again later. If that fails then send me an email and I will take a look.

  • http://www.love-astrology.com Rebecca

    I’m having problems too. It says 0 links for all the sites I’ve added and also the PR column is missing. When I click the refresh link on the individual links within a site I get the following error:

    Fatal error: Call to undefined function: file_get_contents() in /home/virtual/site25/fst/var/www/html/linkanalysis/update.php on line 21

    Any clues??

  • Del

    I’ve checked the code and the PR column is not included in the table so it’s not even trying to pull the image. It’s on a shared host running a version of PHP just prior to 5 if that helps.

    • http://www.blogstorm.co.uk Patrick Altoft

      I will try release a better version next week.

  • http://www.seopractices.com SEO Blog

    Patrick, sorry. I have a problem with the tool. I must be doing something wrong. When I go to: http://www.mysite.com/linkanalysis/
    I get an error message:
    Warning: mysql_connect() [function.mysql-connect]: Access denied for user ‘mydatabasename’@’localhost’ (using password: YES) in /home/user/public_html/linkanalysis/config.inc.php on line 5
    Unable to connect to database

    Can you please give me any lights on this, I will appreciate it.

    • http://www.blogstorm.co.uk Patrick Altoft

      Sounds like you haven’t entered your username and password correctly in the config.inc.php file?

      • http://www.seopractices.com SEO Blog

        Thanks Patrick, I will check on that, keep up the good work!

    Thanks, Patrick, for the head’s up. This will be a useful addition to the ‘bat belt’ of tools we use.

    Hi Patrick,

    It really is a valuable tool, and I look forward to updates to it.

    My domains loaded after I got a new API key from Yahoo – don’t know what was wrong the the first one I got. When I reloaded my domains I got the link count from Yahoo.

    However, the PageRank is missing from my version as well, same as other people have mentioned above.

    I look forward to any upgrades to your tool.

  • http://www.mountainbikesapart.com Colin Gray

    Yep, really good tool, I’m gonna install and will head back with comments after a decent trial.

    Hi Patrick I have not been able to make it work. I have replaced username, password and database-name in the config.php file as you mentioned, but is not working still. Can you show me a sample of how it has to be done properly? Thanks in advance.

    This is whow I replaced it on the file:

    $mainconnection =MYSQL_CONNECT(“localhost”,”myuser”,”my password”) OR DIE(“Unable to connect to database”);

    @mysql_select_db(“mydatabasename”) or die(“Unable to select the database”);

    “and also:”

    $yahoo_api_key=”myyahooapikey”;

    I don’t know what’s wrong? I keep getting the same error:

    Warning: mysql_connect() [function.mysql-connect]: Access denied for user ‘mydatabasename’@’localhost’ (using password: YES) in /home/user/public_html/linkanalysis/config.inc.php on line 5

    Any help would be greatly appreciated.

  • Goran

    I am downloading the software now, will let you know what I think.

    I am hoping you could help me. I have spent the last few months looking for a really simple tool. I was hoping you would know of one that could help me.

    I have a list of urls that we have added a link to, we have the anchor text, and we have the links that the anchor text is pointing to.

    Every program that I have tried requires that we add a SINGLE DOMAIN and then it verifies that the link is pointing back.

    I would like to upload a list of different domains that different links are pointing to.

    Thus, I would add a csv containing the link where the url is, the anchor text and the url the link is pointing to and the software would verify that this is correct.

    Thanks.
