Welcome to the Q&A Forum

Trying to be a good, clean SEO, I have been spending the last two and a half years focusing a lot on building up solid social communities on Twitter, Facebook, Google Plus, Pinterest and YouTube. Back when I began doing this, I believed that old school link-building was on its way out, and that, to stay on the 'clean', White Hat side of Google, social was the way to go for future success in organic search. But my main competitor is STILL buying links left and right, and has absolutely no social media following...and he's kicking my butt more and more in the rankings. And I seem to be losing out with my strategy. So I would really like to know: have any of you experienced proof, first hand, that you can win with SEO by focusing on social signals, and by letting NATURAL, earned links pretty much take care of themselves, by trying to create good content? Because I am FRUSTRATED. I thought I was being one of the good guys. I thought I was going the safer, risk-free way to success. And I knew it would take me longer to become successful this way...but it's been YEARS now, and I still don't see any signs of it happening any time soon !

I have been hit by DDoS attacks lately...not on a huge scale, but probably done by some "script kiddies" or competitors of mine. Still, I need to take some action in order to protect my server and my site against all of this spam traffic that is being sent to it. In the process of researching the tools available for defending a website from a DDoS attack, I came across the service offered by CloudFlare.com. According to the CloudFlare website, they protect your site against a DDoS attack by showing users/visitors they find suspicious an interstitial that asks them if they are a real user or a bot...this interstitial contains a Captcha that suspicious users are asked to enter in order to visit the site. I'm just wondering what kind of an effect such an interstitial could have on my Google rankings...I can imagine that such a thing could add to increased click-backs to the SERPs and, if Google detects this, to lower rankings. Has anyone had experience with the DDoS protection services offered by CloudFlare, who can say a word or two regarding any effects this may have on SEO? Thanks

This question has to do with using Google's Disavow Links Tool. For sites having quite a few subdomains, where those subdomains are listed separately in Google's Webmaster Tools, do I have to upload a separate disavow file for each subdomain? Or, will the file that I upload for the main domain (root domain), also be evaluated by Google for all of the subdomains on that site? I've searched all over the Internet for an answer to this question, but can't find anything.
