For quite some time, I've been baffled by the way I can have a test the TRUE value of an in-bound link (Or a content-article) for the specific website's SEO. In that, I want to see how much it effects the position of the website on search results whilst I cancel all other variants. My thought is that the only way would be to stop LE'ing and Article submitting for a set period of time and measure the effect (And assuming that no natural in-bound links have been setup whilst I do that). This is quite practical - Thus I figure there no TRUE way to measure the after effect and we can only relay on the pre-link analysis. Is that true?
