Welcome to the Q&A Forum

Thanks so much for listening my tweet and coming in here to drop a few lines Marie I think i'll do a mix of both techniques. First, an extensive link cleanup. Then follow my first post's steps (adding the noindex meta tags in all pages as you suggested below) and then do the 301 redirect. Will also add to the mix a redesign, just so the site looks renewed for both users and SE. Will share insights once we complete the migration. Thanks again! PS: will keep an eye for the article on SEW

I have mentioned this a number of times but will rgab the opportunity and say it again.Nobody can fix google's algorith, not even Google itself. It's out of their hands, always was, always will be. The past already shows, that their algorithm gets a lot of things wrong and penalized small biz and ranks spam high, you all got examples of that. They are already bad at identifying machines or humans. Assuming they will go for keyprhases such as Marie Haynes is a writer for example.com...", or "Visit my website at example.com" is simply impossible, for thishappen 99.9% of the guest post authorship tag must include the same keyphrase which i doubt. I find more likely to devalue for example ALL authorship links or even anything with /blog/ in its url, but for that to happen it would mean that 99% of the blogs have the same phrasing which I doubt. If you are wondering how they will try to minimise that, my pov is that they will take into account a couple things such as 1)frequency of posts, 2) how many of these posts are original content and 3)OBL which to my surprise noone mentions here. Matt refers to spam sites that are there for link selling purposes. If you follow his tweets and his latest activities you would know he is after the private blog networks advertised on the most popular black hat forum on the internet. What does that mean? that the algorithm cant track them thus he is trying to figure it out manually. Black Hat SEO is the art of making a machines work to look like it has been done by a lot of humans. Google's job on the other site is to find out who's the human and who's the machine. Google gets better at identifying machines, so the SEO industry gets better at mimicking human behaviour. Guest Blog is an area that got abused but trust me there is a difference having a guest blog on a PR5 site, with unique content and 1-2 links and a total OBL of less than 30 than a guest blog of 500 words with 3 EM ancor links on high competitive keyprhases and roughly 20 comments with link in them. Then again in this case OBL would explode so why would you want a link like that anyway? You lose the value thus wasting money, time and resources.

Thank you Federico! Always happy to see positive feedback with our surprise changes. Cheers!

What I can tell your from the point of a big webshop is that we had to remove all our watermarks (it was just our logo for protection against copyright infringements through our competititors) within 3 business days to avoid to be banned from Google Shopping. So this issue shows the direction Google moves on regarding the image search... If, what you describe, is just the first step, then this will or even is the next one. I would avoid this kind of watermarks as well...

Keri, I am still having the same issues in the weirdest ways. IE: I go to Q&A (logged in), click on a question to post an answer, BAM, logged out. IE2: Logged in in Moz, go to OSE, BAM, logged out, return to moz, logged out too. I already signed off and back on, still no luck. Thanks for the help!

So you basically have 2 different arguments here, both of which are probably true. 1. Raw +1s don't directly effect search rankings  (What Matt Cutts said) 2. Sharing on Google+ likely has secondary benefits that help search engine visibility. (What I said in my Moz article, although not as clearly as I would have liked) Matt Cutts wasn't refuting the article directly (as far as I could tell) but debunking the conclusion that many people were drawing from it. Regardless, we know links are important, and good content is important, and the type of content that earns good links is also often the type of content that earns +1s. Hopefully, you can find a way to pursue it all at once.

Hello Federico, There are enough tag pages still indexed that I'd go ahead and remove that entire directory in Google Webmaster Tools. You may consider a noindex tag on archive pages as well. In regard to your original question, I don't think it would necessarily remove an algorithmic penalty, but it would be good for your brand in the long run. If you're going to do a change like that you might as well do it while traffic is low anyway. Yes, 301 redirect the .net site to the .com site on a page-by-page basis. I would also look into creating a few more useful non-blog pages on the site. Some type of innovative resource that advertisers and/or publishers would find super useful would help you build up the authority of the main site, which would be important considering how relatively few pages and links you have there compared to the blog. An inforgraphic wouldn't cut the mustard, but I'm sure you can come up with something since it is a very well-done site visually.

Hi Federico, I wanted to follow up and let you know that our engineers have released a fix that should stop our emails from crashing Outlook. If you are still running into any trouble with our emails, please let us know. Thanks, Chiaryn

I found the problem myself. My site is under cloudflare, and apparently they were blocking the IP requesting the favicon file. As a fix, I added the favicon to the CDN (which does not go through cloudflare) and the issue is now fixed.
