Panda2 Posted September 16, 2022 Share Posted September 16, 2022 Hi all, Curious as to why GPAnalysis and seemingly other sites only use limited data from certain sources to report on current auction values? ComicLink seems conspicuously absent - is this because of lack of data access/privacy? Or some other reason I haven't thought of? It would seem logical to have some sort of aggregator that truly gives a snapshot of where the market is. Many thanks Panda2 Link to comment Share on other sites More sharing options...
KCOComics Posted September 16, 2022 Share Posted September 16, 2022 This has been discussed in other threads and I can't remember the specific reason why, but I believe Clink hasn't given their permission to use / mine their data. Even their fine print on the site prohibits data mining. I also know bigger dealers often don't disclose sales to GPA. So it's an incomplete picture, but still the best resource for pricing data.

Bird Posted September 17, 2022 Share Posted September 17, 2022 I believe (but may be wrong) that gpa COULD scrape the data but respects clink's desire not to do so. Link to comment Share on other sites More sharing options...

My guess given how antiquated clinks site is their back-ends are no different thus no API. 1999 called - it wants its website back Edited September 17, 2022 by MAR1979 Link to comment Share on other sites More sharing options...
namisgr Posted September 17, 2022 Share Posted September 17, 2022 Love ComicLink as a long-time buyer and seller on the website both. For GPA, they are one of several large national dealers who consider their sales data proprietary and more valuable for them to keep private.

Josh would fall over himself making that data public if he was allowed to manipulate it. The truth is that ComicLink has declined to make their sales data available to GPA since the advent of GPA. So, too, have several other national dealers. It's their perogative based on how they perceive it would impact their business. Doesn't change in the least that ComicLink is a great site for selling books and also a great site for buying them.

Possible they just don't want to spend any money modernizing their tech to accommodate API or other reasons but privacy does not seem to have anything to do with it. Comiclink is a decent venue overall but the site being nearly 20 years out of date tech and feature-wise IMHO does them no favors.

Only a very small fraction of their auction results are part of that archive. I have no problems navigating the site. My main complaint is the lack of availability of back cover scans. alexgross.com 1 Link to comment Share on other sites More sharing options...
Dick Pontoon Posted September 17, 2022 Share Posted September 17, 2022 C'mon guys. Clink vs. GPA was played out right here on the Boards. In the following thread, Ghost Town supplies a link to the original, which is now gone. However, pertinent sections from it are quoted: In a nutshell, as was already mentioned, Clink only wanted to report certain sales as opposed to every sale, GPA did not want to only use only the big-ticket, high end sales. I am glad GPA took that position, but if Clink doesn't want to report to GPA that's fine and their prerogative, the same as any other dealer or website. flchris 1 Link to comment Share on other sites More sharing options...

Perhaps it's buried somewhere in that thread? I can tell you that as a charter member of GPA and having bought comics through the Link since 2005, and having been on the Boards since 2004, I don't recall the Link ever providing GPA with their sales data. If they did for a time, it must have been extremely brief. If you're talking about wanting to supply only a fraction of their sales data, that would be consistent with my earlier post that they didn't wish to supply their data to GPA since GPA's inception. I don't doubt the story that ComicLink may have offered to provide selected sales only (a portion of their data, rather than their data). And they're far from the only ones who've decided that the proprietary sales information was more important than having it reported to GPA.

This makes no sense. He didn't want to provide his sales database. Several other national dealers also didn't want to provide their sales databases. So they didn't. You seem hung up on something other than what I've been posting about. Link to comment Share on other sites More sharing options...

You're just twisting words, like data and database, to apparently stick up for your buddy? Never met him. As for 'words', a sales database is a sales database. They are what GPA sought out to create their own database. There's a whole list of national dealers who refused to give GPA access to their sales databases. Several of them are great dealers, great for the hobby, and the polar opposite of your negative take, in my opinion.

Remember when he encouraged people to pay him with PayPal F+F? Real nice. Curious as to how someone with such little history here believes it’s ok to disparage a well known and respected dealer? My advice, take a couple weeks off the boards to consider what I’ve said and then quit the boards altogether. Link to comment Share on other sites More sharing options...

Thanks, Josh Nathanson www.comiclink.com gpanalysis said: Josh, we can continue going over this. You want to report some sales to us, we would rather you reported all sales. Other than the chart busters section on our home page, there is no identifier as to where the sale comes from. I can't force you to report to us, you can't force me to change my policy. Dealers are free to do what they want, buyers are free to do what they want. I stand by my service and don't believe it misleads in any way. If that is your opinion, well, that is your opinion. You ultimately deal directly with your customers and you are best placed to put your argument forward for whatever position you hold for any and all issues. Is that what makes him a “dirtbag” in your words? 20 years why hide behind a shill ? Link to comment Share on other sites More sharing options...
