Welcome to the Q&A Forum

what type relationship do you see with domain authority and moz difficulty scores? i'm finding a rule of "tens' usually applies.... meaning if da = 45, then difficulty scores of 40-50 are generally within short term reach (3-6 months of simple onpage optimization and an appropriate # ofinbound links to the page). your thoughts/data? just trying to get a feel for a consensus 🙂

I believe, sometimes you may 'deserve' the first position, but get #3. And of course, sometimes you may deserve #3 and instead be #1. All due to a 'randomness factor' in search engine algorithms. I've been holding this hypothesis for quite sometime. Really, it started when I learned about SEOmoz using machine learning to better investigate SEO best practices. I suddenly found myself wanting to learn more about machine learning, and the implications of using it for SEO. I'm by no means able to utilize machine learning myself, but I it appears unsupervised learning would have a real chance of cracking search engine algorithms. Hey, even Stuxnet was cracked! Surely Google/ Bing would know (and account for) this, right?  We can agree they'd obviously prefer a highly skilled mathematician not be able to crack the code. Therefore, I'm led to believe that search engines use some sort of randomness in their rankings. Maybe not much. Perhaps not all the time. But if a random percentage of search results, had a random variable of sorts included in their calculations... wouldn't that be enough to prevent the vast majority of cracking attempts? Thoughts, opinions, criticism? Thanks.

I'm curious to know what other mozzers think about silo's... Can we first all agree that a flat site architecture is the best practice? Relevant pages should be grouped together. Shorter, broader and (usually) therefore higher volume keywords should be towards the top of each category. Navigation should flow from general to specific. Agreed? As Google say's on page 10 of their SEO Starter Guide, "you should think about how visitors will go from a general page (your root page) to a page containing more specific content ." OK, we all agree so far, right? Great! Enter my question: Bruce Clay (among others) seem to recommend siloing as a best practice. While Richard Baxter (and many others @ SEOmoz), seem to view silos as a problem. Me? I've practiced (relevant) internal cross linking, and have intentionally avoided siloing in almost all cases. What about you? Is there a time and place to use silos? If so, when and where? If not, how do we rectify the seemingly huge differences of opinions between expert folks such as Baxter and Clay?

What's the benefits of choosing an mvc framework such as codeigniter or cakephp over wordpress? Wordpress has so many plugins, and a universally known UI for customers, it just saves a ton of time. However, a lot of the 'big guys' like SEOmoz and Distilled(?) use Cakephp and other mvc frameworks so it has me wondering what the benefits are...... anyone?
