I am working on a simple program to analyze the information from Site Explorer in the form of a TSV. Do you think such a program would be useful? What features would you want it to have? Is there anything like it (I could not find anything digging around, but I was not sure what to search?). Note: If you are interested in continually testing the program before release, PM me.
I'm not completely sure what you're making, but it would be really cool if you could create something that could export the backlink data from Yahoo SiteExplorer and find out what the anchor text of each link is and what the pagerank, cachedate, etc. is. Maybe something like the a mixture of the SEO Link Analysis plugin and the SEO For Firefox plugin, and being able to export that into Excel.
I was going to write it as a stand-alone program which takes the TSV file from Yahoo Site Explorer (and perhaps other ones in the future?) I really like your idea about getting the anchor text, I will try to add that. Right now all I have managed to do was have it parse the file and count the frequency of the top level domains so you can see where most of their links are coming from (since it seems that YSE does not put them in a particular order). I was also going to try to write a "blog detector" which would let you return a list of blogs that they have links from in a hope that you might be able to comment on the blogs too. I was planning on writing my program in Java and try to make sure it works in Windows, MacOS, and Linux. Let me know what you think.
Given that Yahoo! sold its search engine's soul to Microsoft not too long ago, nobody really knows whether YSE will even be around or not.
That is actually really true. But I think it is still worth a try. Plus I should be able to have it use some other file, such as the one from Google Webmaster Tools. The only real problem there is that you could not get the same information for competitors' sites. But some of this kind of information could be useful.
Some other cool features: Number of outbound links on that page Whether the backlink is nofollow or not
