No one can know that but you can be pretty sure it is in the thousands or tens of thousands. Why would you want to know?
Just curios, somebody told me that there are about 75000 English directories are in the internet, and I just wondering if this is the right figure.
Almost certainly not. But it all depends on what do you consider to be a directory. There are plenty of categorised links pages that could be considered directories, and that kind of blurs the distinction a bit. There are also some that might be called directories, but are actually closer to free-for-all link farms. No matter how many are out there, there are probably only a few hundred (a different set of directories for each niche, of course) that will make a worthwhile difference to your traffic. The trick is in finding which ones.
I am sure there are close to 50,000 'english' directories on the internet. I have seen lists of 10000/20000 directories before but there must be many that are still not documented by directory lists.
From my experience, I would say that there are no where near 75,000 English language directories. I would estimate that there are less than 15,000 directories.
75'000 Can't be that good then. There was a well respected list once, but the guy who ran it took it down, but it named what was believed to be the main 260 UK search engines and directories on the web. Was a well respected list of established sites too. Ahhhh them days are gone now..... Try this - best I could find: All Search Engines UK - All Search Engines Super Search Lists search engines and web directories. www.allsearchengines.co.uk Listing of dynamic searchable databases with documents that cannot be crawled or indexed by surface web search engines. www.completeplanet.com Search Engine Guide Guide to search engines, portals, and directories. www.searchengineguide.com There are internet guides that can be obtained from Amazon, WHSmiths etc, that will save a ton of search work, and they retail at just £3.99 etc. They list the best, well known databases, directories, engines and guides the web has to offer. I have 2 myself and trust me, they are time savers!
I would estimate that there are less than 15,000 directories. around 10,000 directories dont have page rank.
