SEO Link Analysis Firefox Extension

Remember that Greasemonkey script that I recently updated? Well, maybe you should just forget about that… I’d been working on a version of that script which works on Yahoo Site Explorer and MS Webmaster portal too, and now I’ve gone even one step further: I’ve bundled the three of them, and turned them into a Firefox extension!

If you’re not convinced yet you should go get it now, here are some screenshots:

So here is the SEO Link Analysis extension!

Update: just updated the script to 1.0.1 to fix a change in Yahoo!’s interface.
Another update:
1.0.2 is now available for download.

    Wow, this plug-in is amazing. Great job.

  2. daveBy dave on 12 December, 2007

    Hey Joost,

    I installed the plugin but does it work automatically or is there a place where you can switch it on/off ? It’s activated in the add-ons but I can’t figure out how to get this very nice plugin to show me what I like to know :D

    dave

  3. Joost de ValkBy Joost de Valk on 12 December, 2007

    it works automatically, although you have to restart firefox, just as with every other plugin, and then just do a link check for a domain on Yahoo Site Explorer for instance…

  4. Micah Fisher-KirshnerBy Micah Fisher-Kirshner on 12 December, 2007

    Very nice, although would be nice to be able to download into Excel as well.

  5. Dennis GBy Dennis G on 12 December, 2007

    Joost,
    This ROCKS!

    Or as we say in Dutch, Reetecool… :)

  6. NathanBy Nathan on 12 December, 2007

    awesome – the other day when I read that your greasemonkey script was updated – I thought it would be awesome if it was a firefox extension – and now it is.

  7. hcabbosBy hcabbos on 12 December, 2007

    Still confused. Where do you go in Firefox to use this extension?

  8. TjeerdBy Tjeerd on 12 December, 2007

    Joost,

    The plugin is installed, Firefox has been restarted, but once I logon to Google Webmaster Tools and check the “Pages with external links” section, nothing can be seen (at least, nothing extra).

    Mozilla/5.0 (Windows; U; Windows NT 6.0; nl; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11

  9. Joost de ValkBy Joost de Valk on 12 December, 2007

    remember to click on to a page… nothing will happen in the overview area of the links section.

  10. daveBy dave on 12 December, 2007

    Did that but without positive result..I do some other plugins running maybe that’s the problem ?

    dave

  11. Joost de ValkBy Joost de Valk on 12 December, 2007

    hmm which version of ffox do you run?

  12. TjeerdBy Tjeerd on 12 December, 2007

    Same here… “Pages with external links” is not the overview area.

  13. TjeerdBy Tjeerd on 12 December, 2007

    Ah… My bad – It’s:

    Login -> Links -> Pages with External Links -> click on any number behind any of the links in that overview.

    Sorry Joost – works here :-)

  14. Joost de ValkBy Joost de Valk on 12 December, 2007

    could both of you send me a screenshot? joost at this domain

  15. Joost de ValkBy Joost de Valk on 12 December, 2007

    hehehehe ok tjeerd, glad to hear.

  16. TjeerdBy Tjeerd on 12 December, 2007

    It’s not flawless though – many links are displayed as “link not found”, but a quick check learns the links are there…

  17. Joost de ValkBy Joost de Valk on 12 December, 2007

    Ok now I really need a screenshot, and the URL’s :) all the issues I have encountered in which that occurred, I’d fixed :)

  18. TjeerdBy Tjeerd on 12 December, 2007

    Email with screenshots sent.

  19. Henri van den HoofBy Henri van den Hoof on 12 December, 2007

    Works super for me in Google and Yahoo. Thanks again Joost for your continued efforts on these handy tools :-)

  20. Joost de ValkBy Joost de Valk on 12 December, 2007

    Ok Tjeerd, the problem is that on most of those sites where you do have links, they either use:
    - redirect scripts
    - links with an affiliate code in it, instead of the exact URL

    The script is set pretty “tight”, I’ll try and find a way to make sure that it matches those affiliate URL’s when it can’t find anything else. There’s a few URL’s which I don’t understand, I’ll mail you about those.

  21. PatrickBy Patrick on 12 December, 2007

    Thank you Joost. Great stuff. Works fine in german webmaster tools. Thank you very much ;-)

  22. TjeerdBy Tjeerd on 12 December, 2007

    Joost,

    I haven’t personally checked each and every single one, but I’ll await your email and see what the outcome of that will be. Thanks for the support so far :-)

  23. daveBy dave on 12 December, 2007

    Email send :)

    Works fine in webmaster tools, can’t figure out how to run in Yahoo..

  24. Joost de ValkBy Joost de Valk on 12 December, 2007

    @Dave: you’re using normal Yahoo search, and not the Yahoo SiteExplorer, big difference there ;)

  25. daveBy dave on 12 December, 2007

    I knew I was doing something wrong :d

  26. tingeltangeltillBy tingeltangeltill on 12 December, 2007

    thanks for that genius plugin!

  27. martijn anschutzBy martijn anschutz on 12 December, 2007

    Awesome extension Joost!
    thnx for sharing

  28. TripleOxBy TripleOx on 12 December, 2007

    Very cool! Can you explain what the different colours and strike-throughs mean?

  29. Joost de ValkBy Joost de Valk on 12 December, 2007

    Yes, I should copy over that info from the original greasemonkey page I guess :P

    orange strike through is a nofollow link, black is normal, red is not found.

  30. hcabbosBy hcabbos on 12 December, 2007

    Alright. Now I understand this tool. This is sweet but I too am finding “Link not found” on pages that are operational and have no redirect scripts and/or affiliate code.

  31. RobbertBy Robbert on 12 December, 2007

    Very nice extension, but I would like to see an option to sort by PR and website :-)

    Hope you can implement this in a later version!

  32. LonghandBy Longhand on 12 December, 2007

    Congratulations for the extension, nice work!

    Are You planning to update it later to make compatible with Site Explorer too? (ho have the ability using operators like site when checking backlinks.

  33. Eric BlackwellBy Eric Blackwell on 12 December, 2007

    Great tool Joost! Still giving it a thorough test, but I like it!

    Eric

  34. JabBy Jab on 12 December, 2007

    Hi Joost,

    first of all, thanks for sharing the extension. Nice job. Hopefully you do not stop developing it. From the questions in this thread, you can see where work should be done. Mostly usability things.

    Regards, Jab

  35. Hobo SEOBy Hobo SEO on 12 December, 2007

    Boo Hoo! I’m getting a download error on my Mac. :(

  36. Joost de ValkBy Joost de Valk on 12 December, 2007

    @Robbert: that’s harder then you think :)

    @Longhand: it does work with site explorer, just not with normal Yahoo Search, before I do that, I have to find a way to disbale it.

    @Hobo SEO: I’m a Mac user, so I feel the pain… What’s going wrong? Which version of ffox?

  37. PromoMastersBy PromoMasters on 12 December, 2007

    Wow – great tool. Seems you are going to get the new Matt Cutts – live hacking Google Webmaster Tools. Congratulations and thanks for giving this tool to us. I would need (buy) another tool. Maybe contact me? But I’m no millionaire :-)

  38. Joost de ValkBy Joost de Valk on 12 December, 2007

    Hehe PromoMasters you can always try, at least you can pay in something else than dollars :P

  39. Hobo SEOBy Hobo SEO on 12 December, 2007

    Hi Joost – I was getting an error (a “download error”) a couple of times but just tried it again and hey presto….. now giving it a try…. :)

    I’ll sphinn of course – kudos for the free tools!

  40. SEO Company CanadaBy SEO Company Canada on 13 December, 2007

    Hey Joost, I’ve already found a couple bugs. The first thing is if the site exists on a page that has multiple links it picks up the first one which can be deceiving. Some directories have both an image of the site, and the URL. So it picks up the image instead of the link with anchor text.

    The second is it is reporting a lot of sites saying Link not found, when they are there (good examples of this are on MyBlogLog and LinkedIn links are visible when I view page, but not according to the FF plugin). Cheers, and good work!!

  41. deInternetMarketeerBy deInternetMarketeer on 13 December, 2007

    This is the great tool i was looking for!

    Nice job!

  42. SEO ScotlandBy SEO Scotland on 13 December, 2007

    Well, I was convinced with just the google webmasters tools script, and you’ve taken it a step further! Great work.

  43. StephenBy Stephen on 13 December, 2007

    Joost – Looks good but getting an alert ‘Error: matches has no properties’ in YSE..?

  44. TomBy Tom on 13 December, 2007

    wow great work. best regards tom

  45. Joost de ValkBy Joost de Valk on 13 December, 2007

    @Stephen: hmm, any chance of emailing me the URL for that one?

  46. Joost de ValkBy Joost de Valk on 13 December, 2007

    For those of you who got the “matches” error on Yahoo: install the newest version, 1.0.1 that should fix it!

  47. SebastianBy Sebastian on 13 December, 2007

    Thanks, this tool works great, even with my ancient FF version. I’m just curious why it spams the referrer stats with “https://www.google.com/webmasters/tools/externallinks” hits that actually are requests which would work without an HTTP_REFERER too.

  48. Joost de ValkBy Joost de Valk on 13 December, 2007

    hmm Sebastian, good point, i’ll check it out for a later version.

  49. deInternetMarketeerBy deInternetMarketeer on 13 December, 2007

    Worked fine in the beginning, then matches errors.
    Installed new version and with link: it works fine but with linkdomain: the matches error shows up again.

  50. seo bristolBy seo bristol on 13 December, 2007

    Hi Joost
    It’s looking like it’s going to be a fantastic tool but I’m using 1.0.1 and I’m still getting the matches error…

  51. Joost de ValkBy Joost de Valk on 13 December, 2007

    SEO Bristol: can you send me a screenshot + the url? And can you verify that you’re indeed running 1.0.1 by looking at your add-ons menu? Firefox has the nasty habit of caching stuff :P

  52. Joost de ValkBy Joost de Valk on 13 December, 2007

    And another update to fix issues with Yahoo! SiteExplorer, the link now points to version 1.0.2 :)

  53. Joost de ValkBy Joost de Valk on 13 December, 2007

    @Sebastian: latest version removes that referer spam as well.

  54. SebastianBy Sebastian on 13 December, 2007

    Thanks Joost – you’re fast :)

    1.0.2 works beautifully – that’s so impressive to get it sorted so quickly.
    Many thanks

  57. ArnieBy Arnie on 13 December, 2007

    Awesome! Installed and looking at great data in less than 2 minutes. Great tool.

  58. SEO Company CanadaBy SEO Company Canada on 13 December, 2007

    When you install a new version make sure to remove any old ones or you will have multiple showing up in your Addon screen.

  59. Joost de ValkBy Joost de Valk on 13 December, 2007

    @SEO Company Canada: yes indeed, thx for mentioning that, that’s because I still make the extension the lame ass way, I’ll fix that soon.

  60. nv1962By nv1962 on 13 December, 2007

    Awesome Firefox extension, Joost. Don’t want to clutter up with comments elsewhere, but I have two of your WP plugins in use on my little blog, and mentioned / linked back on the “about” page. The contact form thingie is great! Back on topic: now that I’ve figured out that it drills down on external links to individual pages, I appreciate it even more. Really handy tool, even though in my case it’s more about satisfying my curiosity than justification (it’s a low-traffic personal blog after all – which is fine with me!).

    Hele fijne feestdagen gewenst!

  61. Joost de ValkBy Joost de Valk on 13 December, 2007

  63. Financial BlogBy Financial Blog on 14 December, 2007

    Hey Joost,

    Great script – it was working superbly for me the first day but now I get an error in siteexplorer – “Error: matches has no content”. I tried installing the 1.0.2 bugfix but it hasn’t helped.

    Any ideas?

    Thanks

  64. Joost de ValkBy Joost de Valk on 14 December, 2007

    Hi, Could you: A check if you’ve installed the new script correctly and removed the old script? Just look in your add-ons and check whether you have just the 1.0.2 release installed. B if that’s the case, sent me an email with the URL and a screenshot :)

  65. Financial BlogBy Financial Blog on 14 December, 2007

    Hi Joost,

    That did the trick – thanks! I didn’t realise that it wouldn’t overwrite the previous addon.

    It now works like a charm again – you’re a genius!

  66. WEBOSISBy WEBOSIS on 14 December, 2007

    Hey Joost, would you recommend using this one over the Greasemonkey script?

    I see that it also supports Yahoo and Live, but does it do anything different inside GWT?

  67. Joost de ValkBy Joost de Valk on 14 December, 2007

    @WEBOSIS: yes. It’s much improved since.

  71. seccusBy seccus on 17 December, 2007

    Hi!

    I did what it should be done to install the plug-in. It says to restart Firefox. I did. But where is SEO??? Nothing. Not in the toolbar section. I reinstalled many times and nothing happened again. My computer work with Vista.

    Thank.

  72. Joost de ValkBy Joost de Valk on 17 December, 2007

    @seccus: go to a links page in Google webmaster tools, or do a linkdomain: query in yahoo site explorer, and see what happens. (and read a bit more next time :P )

  73. seccusBy seccus on 17 December, 2007

    Sorry. I did what asked. I do not see what supposed to happen. All these links where there or were like it when I made a linkdomain request on Yahoo last time before the SEO installation. You ask for screenshot to understand a problem, don’t you think it may help rookie like me to show what we suppose to get?

  74. seccusBy seccus on 17 December, 2007

    Hey Joost -

    Killer plug-in. Blackwell from ericonsearch sent it to me, and I think it’s one of the strongest SEO tools I’ve used in a long time.

    Quick question for you – it’s working great w/ the yahoo site explorer & webmaster tools, but when I run a search on yahoo like this:
    “linkdomain:competitorsite.com -linkdomain:mysite.com” it’s not working. Is there any way to make it work on this type of search?

    Thanks!

    Eric

    I was doing a lot of yahoo site explorer searches with the seo-link-analysis add-on installed, and suddenly stopped getting any page rank results returned in google toolbar. I had to reset my i.p. address to get it back. I am pretty sure that Google cut me off due to multiple calls for page rank from site explorer
