I am working with a company that is trying to build their online authority and they want to avoid any penalties from Google and other major search engines.
The site is a social network (adult related) and users can create public profile, post links, images, etc. It is an adult social network for people that want to make money talking on the phone.
So the question is, is it a good idea to nofollow all external links? Because it is hard to gauge the quality of sites that we may be linking out to and I don't want to have any issues with this..
Thanks!

This article on Google suggests you should nofollow untrusted user links.
If you can't or don't want to vouch for the content of pages you link
to from your site — for example, untrusted user comments or guestbook
entries — you should nofollow those links. This can discourage
spammers from targeting your site, and will help keep your site from
inadvertently passing PageRank to bad neighborhoods on the web.
I'd probably keep your own links as follow, and make some effort to seek out and remove dodgy links, though - nofollow does not protect your users.

The safe route would be, yes, to add nofollow to all of your outgoing links if you're going to allow users to be able to insert any link they wish.
A lot of large social networks and forums do this and have no issues.
I hope this helps some.

I'm developing an eCommerce website, whose users can be of two kinds; ordinary people and business. The difference between them are short, business users has a special discount, so their prices are different; and a couple more of minor changes compared to ordinary people.
My question is if it matter if this two users has the same URL for the same modules, for example, if they are watching the catalog:
myapp.com/catalog
A business users could be:
myapp.com/business/catalog
I'm asking this question because of the SEO positioning; I need to know if this makes any difference longer than making the same URL for two kind of users.
Thanks.
In order to distinguish between ordinary people and business people (and show them different prices) they have to be logged in to your website. There is no need to make different URLs from the SEO point of view, because an indexing bot cannot log in and therefore cannot see the difference between two kind of users.
But this really depends on the approach you choose. You can make both of the pages with different prices visible to anynone and decide right after they log in if they can buy for the price. But I think it makes the shopping process too complicated from UX point of view. Imagine that ordinary user goes to business page, put goods with discount prices in to his shopping cart, logs in and then sees different prices because the system didn't recognize him as a business person. It can be very misleading for unexperienced user.

If I register a domain abc.com, but point via a redirect to another domain's subfolder like def.com/abc, what's the effect on SEO? Will Google index both abc.com and def.com/abc and display them for keyword "abc"?
Is there any way to avoid this or pomote abc.com so it displays more prominently than def.com/abc?
What's the best practice in this scenario?
Thanks for the help.
I'll refer to Google's official SEO guide. Here's a link to the full guide.
Provide one version of a URL to
reach a document
To prevent users from linking to one version of a URL and others linking to a different version (this
could split the reputation of that content between the URLs), focus on using and referring to one URL
in the structure and internal linking of your pages. If you do find that people are accessing the same
content through multiple URLs, setting up a 301 redirect from non-preferred URLs to the dominant
URL is a good solution for this. You may also use canonical URL or use the rel="canonical" link element
if you cannot redirect.
Since Google relies on links to your pages, you're going to have an issue if people link to one URL versus another. So in short, yes, that will probably have an effect on your optimization.
Edit: Google's algorithm may be smart enough to know your redirect and follow it when indexing your pages. Probably your best outcome will be to not do the redirect and instead point the domain at your content. The second best will be to use the HTTP 301 status code.

Sometimes when I search in Google, appears a website and just below... several links from that website. Sometimes also (I don't know if it's related) I click on a result and the website shows me the page with the search terms highlighted.
How does that work? I mean, which technology or standard do I have to implement in my website in order to archieve those effects?
Thanks
Do you mean sitelinks?
Google's systems analyse the link structure of your site to find shortcuts that will save users time and allow them to quickly find the information they're looking for.
They only show sitelinks for results when they think they'll be useful to the user.
You can read more here http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=47334
EDIT
To answer your question, all you can do is make sure you have a well formed site with clear navigation which your users can use and find useful. If your site popular then Google will do the rest.
Google shows highlighted search terms on its cached pages
When you're viewing a cached result the page is stored on Google's servers - so they can modify as they wish (highlighting search terms).
If you're viewing them on actual websites this is due to either:
Google wrapper around the page (such as mobile viewing)
Google toolbar (or similar)

which domain to use and which to forward.. SEO reasons. discuss! [closed]

I am developing a site for a client and they currently own two domains.
howafarms.com and grassfedbeeffl.net
The current site has howafarms.com traffic forward straight to grassfedbeeffl.net. My question is.. which one should I use as the main url and which should I forward. Normal logic tells me howafarms.com should be the main url. But... from an SEO standpoint, I will already be winning the battle in google rankings if someone types howafarms.. so the added weight from the domain wont be very effective. On the other hand, if I use grassfedbeefl.net, I think the benefit from those words in that domain will help SEO quiet a bit more.
What is your opinion on this?
Google does give a bigger weight to EMD (exact match domains). It has been proven numerous times that ranking an EMD is much easier than non EMD.
If "how a farms" is a popular search term, then choosing howafarms.com is better choice than grassfedbeeffl.net. However, if people are searching "how farms" instead "how a farms" then howafarms.com adds no great value to your SEO campaign. Because it is no longer considered EMD.
Just to give you an example, try to search "seo tips" in Google search. Notice how many EMD are sitting at the top results? In spite them having a poor content. On the other hand quality sites which give you real SEO Tips are buried far away in Google search, just because they are not EMD and have to work harder.
In my somewhat qualified opinion there is really no need to change a domain name for SEO reasons. Google really couldn't care less what your domain name states because a domain name is no indication of content quality.
The only benefit that should concern you is the benefit to the user. If you think one domain will benefit users then go with that one, otherwise don't change a website to manipulate metrics no one outside of Google truly understands.

The web site in question is www.eventid.net; my web based app will redirect the user to the site and send an event id in the url. The redirect will be: http://www.eventid.net/display.asp?eventid=1003&source=Microsoft-Windows-Security-Licensing-SLC
Do you think I can do this?
I have contacted the site owners with no reply.
It's a public website, of course you can.
It'd be a different matter if you were screen-scraping their results for your own application, but from your description that's not the case.
If you were operating a web site in Germany, and your site had a deep link to a Stackoverflow article, and that article contained copyrighted code from a German company (posted by an employee, for instance), that company could easily get you in trouble at any German court.
US courts have been much more lenient, so if you are doing business solely in the US, I would not worry too much, as long as you don't violate the Terms of Use here.
So, I think the answer "Of course, it is a public site" does not do justice to the potentially complicated legal issues that can arise when you take the question into an international context.
Some examples (only the big ones make it into English language news):

http://news.cnet.com/8301-1023_3-10064740-93.html
Read through their Terms of Use carefully. Make sure you avoid violating their trademark. If it's not clear that you are redirecting to an external site, you may want to make it clear so your users aren't confused.
