    Very nice to read!

    Is the algorithm still being tweaked and improved? There are lately, last weeks, noticable differences in the flow metrics. The citation and trust-flow keep improving altough the (amount of) links is not changing according to Majestic SEO.

      We have not changed algorithms but we’ve increased fresh index size considerably. Since the flows also use internal links which we do not report on it’s possible in some cases for flow values to change without number of external links changing. Also bear in mind that external links themselves can get MORE flow and thus pass more to your site.
