Will Google penalize for redirects related to a company merger?
-
Company A is set to acquire Company B. As part of the merger agreement, Company A will be redirecting the linking domains of Company B's website (over 1,000 links) to company A's website.
Will Google penalize Company A for redirecting Company B's 1,000 linking domains to Company A's website at one time? If so, would it be better for Company A to redirect Company B's 1,000 linking domains in waves?

Thanks for your help on this question Ryan, irvingw and Gianluca.
Being that I am still an SEO newbie, looking back at my original question, redirect probably wasn't the correct word to use and my example could have been clearer and more concise, my apologies (still learning).
There's nothing black hat going on here, so no worries; but thanks for the words of warning. The links being discussed are from sites like Wikipedia, and other public profile pages. We're making sure that those public pages point to the correct URL. And since Company B was acquired by Company A, those public profile URL's should no longer point to www.CompanyB.com. They should all be pointing to www.CompanyA.com, instead.

No one knows what Google's algorithm metrics are, and even if they did the algorithms receive 500 changes per year.
As I shared, it depends on how many links the site already has established. If your site has a million linking domains then 1000 more is not even a thought. If your site has only 1000 linking domains then doubling the links overnight will surely set off algorithmic alarms.
It is my best guess Google would look at patterns. If a site has existed for 2 years and has 1000 linking domains, that averages to 42 new linking domains per month. I would feel comfortable doubling or tripling that number in a given month, but not going to much past that point.
I would also caution if you truly have control to 1000 unique linking domains, you need to have an extremely sophisticated black hat operation established. That would require 1000 unique domain registrations, 1000 unique c-block IPs, 1000 unique web designs, each site would have to earn unique back links, etc. The overwhelming majority of people who attempt to set anything like this up are caught and the entire network is categorized as an attempt to manipulate search engine rankings, and all links from all sites would be devalued.

"If you are talking about generating 1000 unique links to Company A's site from 1000 linking domains, there is a concern about having such an unnatural growth in links. It is dependent on the Company A site. If the site has a million links, then no problem. If the site has only 1000 links and you double overnight, that can possibly trigger an algorithmic penalty."
Actually, this is exactly what I'm talking about. What then would be the ideal number of links to redirect so as not to be penalized?
-
Well... yes, they are quite a lot.
But that agreement means also the disappearance of the site B? Or the merge of site B in site A.
Because if it is the second option, you could redirect all the site B (better if you take care of page similarity and not just 301 to the site A home page).
Then in GWT of site B you can advice Google that Site B is moved to site A. That way you are officially saying to Google: "Hey Matt, I'm moving and also my links are moving with me; therefore don't take wrong decision, because nothing black is happening :)".

If I am understanding you correctly, you would be redirecting Company B's website to Company A, correct? If so, you are welcome to redirect the entire site whether it is 10 pages or a million pages. It is a normal part of the internet and there is no penalty involved.
When you refer to 1000 linking domains it sounds like you are not referring to Company B's website, but the many domains which link to Company B. Normally a company does not have direct control over the sites which link to it. For example, it is possible for 1000 people, companies or SEO websites to link to this Q&A thread. SEOmoz has no control over who links to the thread. If SEOmoz wished to move the thread, they could do so and 301 redirect the thread, but they cannot go to the 1000 linking domains and force them to change the URL.
I believe you are simply referring to redirecting Company B's website in which case there are no concerns. If you are talking about generating 1000 unique links to Company A's site from 1000 linking domains, there is a concern about having such an unnatural growth in links. It is dependent on the Company A site. If the site has a million links, then no problem. If the site has only 1000 links and you double overnight, that can possibly trigger an algorithmic penalty.

You can redirect them all with no issues if the companies websites are compliant. That is they are not penalized domains, and also not overly interlinked to each other.Too many websites for one company is against Googles rules, you're only supposed to have one horse in the race.
My suggestion would be to look at each site one at a time and vet it for compliance, once you have determined that it's a healthy site with no bad link building done on it, it would be safe to 301 redirect it to your new site.
This is just being super cautious though, because theoretically you have no control over who 301's a site to your domain. If Google penalized a site based on that then competition would take penalized spam domains and 301 them to the competitions sites in an effort to get them penalized. That being said, I wouldn't want any penalized sites to be 301ing to my site just to be on the safe side.

Google Reconsideration Response Time
Hi all, 3 of my websites have received a massive hit from Penguin/Panda due to exact phrase links. I have had all the links changed so that they are completely different, and submitted a reconsideration request to Google. Would anyone be able to tell me roughly how long it takes to get a response from a Google reconsideration request? Thanks, Anthony

Will Ecademy closure affect websites google ranking
Hi, i think i must be the only one that did not know about Ecademy sale, well almost. In the past week I have had a number of people contact me who are angry that they did not receive an email about ecademy business network being sold off. These people are more than angry about their monthly payments leaving their bank acounts and not having access to the new site which is here www.sunzu.com/ Although a lot of people are angry of the handling of this, an important question i would like to ask is, with ecademy no longer being around, does this mean that all the hard work of people writing articles on ecademy and gaining link juice, will all this link juice vanish look forward to hearing your thoughts

Google is no longer ranking home page but sub page lower, why?
We were ranking on page 2 and number 4 for the key word motorcycle tires. Google was ranking our home page jakewilson.com; however, we have been adding new content to our site and doing some internal linking. We pointed some links about motorcycle tires to http://www.jakewilson.com/cl/52/Motorcycle-Tires and now that page ranks but on page 3 not 2. Any thoughts?

Total Links vs Google Webmaster Site Links
I am interested why the numbers between SEOmoz and Google are so different. In SEOmoz we only show 17,000ish links from 190ish domains. In Google, we show 200,000+ links from 370 domains. Why is there such a dramatic difference?

We have written great content - how will people find it?
Hi We have allocated resources to write some great content (how to's, best practice, videos) etc which will benefit customers as they will find it a useful resource. We are using this not as a sales channel but as a trust and information resource to build a community It is currently located about 2 levels deep in our website, what are the best ways of getting people to find these articles on the web? I have placed some social sharing icons at the bottom of the page to Facebook and Twitter but are there other channels because at present the only way they will find this information as if they visit our website. Do we also need to be practive and distribute this content around the web perhaps as a guest writer? which raises duplicate content problems as it would also be on our website or is there a better approach?

Can being on to many directories cause a penalty from Google?
If a URL is on hundreds of different directories would that be enough for Google to penalize a website?

How best to link multiple related websites.
I have a handful of e-commerce websites that overlap each other some in the same niche. I have already heard that it would have been best to make just one website, but this is not practical for me. Our business model goes back to a time before the internet. We have relationships with manufacturers where they refer business to us because we brand web sites which will not switch customers to competing brands. Our agreements make it ok to link to other websites so long as we have branded websites that focus on the specific manufacturers. For SEO, what is the best way to link these sites? Site wide links in footers.? Single links at on homepages? One way links from the most powerful site? Some other method? We have been wrestling with this question for some time.
