Lately, I've been seeing 4 sites in and out, almost a monthly cycle for last 2-3 months, submit, 2-3 weeks later, site is prominent. Ranking declines over next 3-4 weeks until it drops of the radar... resubmit...
Anyone else? Any rumors about Direct Hit or click pop newly into the algo?
And Ted, that is why I have some hope that NL will not go ppc and will be around for the long term. They are the only SE to make a go of it in the selling of pure information. However, I think when they lost the US Gov search engine endorsement, they felt they lost a huge investment of resources with zero return.
I look at NL as a sort of poor mans Ne x u s Le x u s (obfuscation intentional).
