Welcome to the Q&A Forum

Hi Vinny, In general LinkScape updates every 30 or so days. So if you gain a new link or 3 part way through LinkScape's cycle it's very possible that it will not be included in the most recent update. Also, as awesome as it would be if LinkScape's directory were as large as Google's, it isn't. This is mostly just due to technology constraints I'd guess, and not having dozens of ENORMOUS data centers like Google. Because of this there is a chance that some links will not be picked up (especially if the links might be on really new sites, or maybe rather spammy ones). So it really turns into a waiting game to see if those links you know exist are picked up on the next LinkScape cycle or not. Finally, unless I've managed to totally avoid it this whole time, the index doesn't have any sort of history. The amount of data storage required to maintain such a history would be crazy in conjunction with how often they currently update their index. To name drop one of SEOMoz's competitors (sorry guys XD ) majesticseo.com does actually offer historic indexing services. I don't know how in-depth they are when you're fully subscribed, as I've never been a paying member of their services. It may be something worth checking out. And if someone comes into this question and corrects me about SEOMoz having historic index access, definitely do that instead! I know I will =P.

Finally, it seems to be every 1 month and half, two month. Look on the page's tool : http://www.opensiteexplorer.org/ Last Index Update: Feb 21th, 2011 Next Index Update: April 2011

Danny Dover's book looks like a text book but reads more like a blog and focuses more on how to be an SEO practioner and what you need to do and know whereas the Art of SEO is more about the SEO knowledge. I'd definitely recommend reading both.

Hey Paul- If you are already receiving an A grade for the page, I don't see why you would need to drop those 13 characters before it. Remember that those words can entice users to click on your site in the SERPs if it looks more attractive than your competitors. For example, look at the SEOmoz Title: "SEO Software. Simplified." Im sure simplified is not one of their major target keywords, but helps both users and search engines.

Thanks David, I thought that if my competitors' links were more authoritative it would have also shown in Domain MozRank, Domain MozTrust, but perhaps not. Will have a closer look. Tom

Hi Tim, There is a new version of OSE in the works currently, though I'm not sure if that feature will be in there.  I know that the web app is set to have some for of historial tracking so stay tuned.  You can also submit feature requests here: http://www.seomoz.org/dp/change-log

I think what I've done wrong in the past is to go to sites in my field and get links from them. I should go to sites outside my field that relates to my specific page or blog, this way it's relevant, not trying to steal their traffic...

Thanks to both Craig & Rune! I will definitely be utilizing your comments!

There are two great posts in SEOmoz itself that I found very useful; Competitive backlink analysis and Using Google CSE Both use the tools within SEOmoz itself and will help you mine for link candidates more widely, and then analyse and target the links you want to gain in depth. With respect to which pages to link to, using the above tools will enable you to link with a wider variety of anchor text to specific pages - keeping the relevance as high as possible. Personally I would be inclined to balance between category and product - if you can get a targeted link for a niche phrase to a specific product page - do it, if the domain you are gaining the link from is in your field, but not product specific, go for the category link.

I have to admit that's exactly what I would do so I can't really suggest anything more exciting. Maybe someone needs to make an app that uses the SEOmoz api for intranet pages? No problem about the answer, very happy to chip in. Hopefully someone else with a better idea will drop by shortly.

It all depends on what do you mean for "most important". What I suggest you is to not limit the examination of the backlinks into OSE (I imagine you are using it for competitive analysis), but to export the raw datas in .csv format and then start using some Excel magic, in order to analyse the backlinks the way you consider the most suitable to your needs.

Thanks for the info Baptiste. I'll add the RSS feed and subscriptions to new questions in certain categories to our queue. Please let me know if you have more feedback or ideas for improving the system!

Hi, I confirm this problem is not new, it already existed 5 years ago when I started doing SEO. At that time, I ask about this and I've been told that is might be because the 10 results and 100 results queries were not returned by the same servers that might have not use the same algorithm. I also noticed a strange behavior from Google two weeks ago that navigating from pages 10 to page 1 wouldn't display the results in the same order than navigating from page 1 to page 10. Like if once you reached the 10th page, I would be then using a different server using a different algorithm. Best regards, Guillaume Voyer.

I agree that you should be able to upload a big image, but unfortunately most of the libraries I've seen for doing backend image manipulation don't do a great job scaling down large images. They often end up blurry. Whereas a good graphics program will sharpen properly and you'll end up with a much better looking image. Would be interesting to see if yours looks better if you upload a pre-scaled one.
