I built a site that I am very proud of. The content is top notch and most sites are charging a monthly fee for what I give away for free.
About 10 months ago I started sending 10 emails a day to webmasters that link to my competitors (pay sites). I see a huge success rate and people love to link to it. I'm running out of sites to contact that are in a similar niche.
As a result of all the solid links my rankings have jumped leaps and bounds.
Is that all going to start to tank, if I don't continue to find new links?
Any input is greatly appreciated.
