Over the past few days I have been testing a bunch of indexing services. Unlike most people I have direct access to my nginx server/google-spider logs and the pages I want to index are all hosted by me. So I can see exactly when a google-spider visits my site. I've just tried 6 services.... NOT ONE HAS SENT A SINGLE GOOGLE SPIDER TO MY SITES No clue what these services are supposed to be doing, but if google-spider doesn't visit your link... guess what... it won't get indexed. P.S Yes I replicated test with working methods/services and spiders arrived just fine.
