My subdomains are going to be city names:
miami.mysite.com
newyork.mysite.com
I don't know how most sites handle subdomains. My idea is simply to point them all to mysite.com and somehow get the subdomain name with PHP so that I echo the city posts and content with PHP.
Providing all subdomains have different Titles and Description. Will google index each subdomain as a different website?
Yes, Google will index each one as a separate site. However make sure you consider the pros and cons. Here's a good starting point: http://www.seomoz.org/blog/understanding-root-domains-subdomains-vs-subfolders-microsites
My opinion is go with subfolders (e.g. mysite.com/miami) instead of subdomains, mainly because consolidating inbound links to a single hostname will build more authority over time than if the same link juice is diluted among hundreds of subdomains. Also I think it would be hard to build enough unique content on each subdomain to support or justify having a separate site.

Sub-domain such as http://blog.example.com is considered a part from http://example.com or it is concerned as different domain by Google?
Google consider it to be part of the same domain. For example, blog.example.com is 'linked' to example.com. A good example is Wikipedia. Do a quick Google search for a well known entity or topic (i.e. 'England'). The second result is en.wikipedia.org/wiki/England - a subdomain of Wikipedia.
Long story short: using a subdomain shouldn't affect your search ranking.
I am just a learn in the field of SEO and i have a main domain and an addon domains. Both have separate websites. Consider main.com is my main domain and addon.com is my addon domain name which is pointed to a sub directory called "addon".
I can access addon.com by using the following 3 ways.
addon.com
main.com/addon
addon.main.com
Are these urls are indexed separately by search engines? If so how can i prevent this?
Does Search engine think main.com/addon as a page in the main.com?
I am not sure i need to worry about all these things or just leave it as it is. I searched to google but couldn't find a right answer.
It may be too late to answer. However, it may benefit others.
Primarydomain and subdomain or addon-domain will not be linked by the search engines automatically, unless you link them purposefully or inadvertently. Except all conditions are true:
Your web root normally public_html has no index page
Directory indexing of your web root is opened, eventually
exposing/linking your sub-folder -which is attached to your
addon-domain- to google and entire world.
In that scenario robots.txt solution is not recommended, because search engines may ignore robot.txt rules.
Reference
Google will only index pages if they are linked to or listed in the sitemap. You can stop the addon.main.com or main.com/addon being indexed by using noindex tags:
<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
or disallowing it in the robots.txt
The search engine will consider main.com/addon as a page of main.com - if sites are completely separate i'd recommend using a separate domain (preferably a keyword rich domain) but it's up to you really
We have three domain names with the same content. For the three domains, it will return a 200 OK HTTP code. It will look like duplicates of the same content. If there is a canonical tag on every page it will be better.
The best would be to create a redirection on the subdomain panel in cpanel so that at least addon.main.com would redirect to addon.com
Then, you can add a robots.txt to the root path of the primary domain and add
user-agent:*
disallow:/
so that no robot will visit main.com/addon
Google gives less weight to subdomain hosted site of another domain.
Superbad for SEO
If you are hosting for SEO and love the convenience of cPanel, then forget hosting domains as addon domains.

Its an excellent question, often overlooked by SEO professionals. +1 for you
If my website only responds to www.example.com, and not example.com, does this affect search rankings at all? I haven't found anything to confirm or deny this for any major search engine, and I'm curious.
i was reading an article on this a while back from ScottGuthrie that relates to IIS SEO Toolkit - the main points are as follows:
4 Really Common SEO Problems Your Sites Might Have
Below are 4 really common scenarios that can cause your site to inadvertently expose multiple URLs for the same content. When this happens external sites linking to yours will end up splitting their page links across multiple URLs - and as a result cause you to have a lower page ranking with search engines than you deserve.
SEO Problem #1: Default Document
IIS (and other web servers) supports the concept of a “default document”. This allows you to avoid having to explicitly specify the page you want to serve at either the root of the web-site/application, or within a sub-directory. This is convenient – but means that by default this content is available via two different publically exposed URLs (which is bad). For example:
http://scottgu.com/
http://scottgu.com/default.aspx
SEO Problem #2: Different URL Casings
Web developers often don’t realize URLs are case sensitive to search engines on the web. This means that search engines will treat the following links as two completely different URLs:
http://scottgu.com/Albums.aspx
http://scottgu.com/albums.aspx
SEO Problem #3: Trailing Slashes
Consider the below two URLs – they might look the same at first, but they are subtly different. The trailing slash creates yet another situation that causes search engines to treat the URLs as different and so split search rankings:
http://scottgu.com
http://scottgu.com/
SEO Problem #4: Canonical Host Names
Sometimes sites support scenarios where they support a web-site with both a leading “www” hostname prefix as well as just the hostname itself. This causes search engines to treat the URLs as different and split search rankling:
http://scottgu.com/albums.aspx/
http://www.scottgu.com/albums.aspx/
full article at http://weblogs.asp.net/scottgu/archive/2010/04/20/tip-trick-fix-common-seo-problems-using-the-url-rewrite-extension.aspx
Google treats www.example.com and example.com as two separate domains (since 'www' is technically a sub-domain). Neither is better than the other in terms of SEO, as long as you don't mix and match links - i.e. some links point to example.com while others point to www.example.com.
If you don't have any redirects from one to the other, then links into the site (and so visitor traffic) may be split between the two sub-domains, effectively meaning you're competing with yourself in search engine rankings. It's probably a good idea to pick one (either example.com or www.example.com) then set up redirects on the other domain, and/or add canonical links to pages so that search engines know that the pages should be treated as the same site.
See here for more on canonical links in www vs non-www links.
When I searching our web site on Google I found three sites with the same content show up. I always thought we were using only one site www.foo.com, but it turn out we have www.foo.net and www.foo.info with the same content as www.foo.com.
I know it is extremely bad to have the same content under different URL. And it seems we have being using three domains for years and I have not seen punitive blunt so far. What is going on? Is Google using new policy like this blog advocate?http://www.seodenver.com/duplicate-content-over-multiple-domains-seo-issues/ Or is it OK using DNS redirect? What should I do? Thanks
If you are managing the websites via Google Webmaster Tools, it is possible to specify the "primary domain".
However, the world of search engines doesn't stop with Google, so your best bet is to send a 301 redirect to your primary domain. For example.
www.foo.net should 301 redirect to www.foo.com
www.foo.net/bar should 301 redirect to www.foo.com/bar
and so on.
This will ensure that www.foo.com gets the entire score, rather than (potentially) a third of the score that you might get for link-backs (internal and external).
Look into canonical links, as documented by Google.
If your site has identical or vastly
similar content that's accessible
through multiple URLs, this format
provides you with more control over
the URL returned in search results. It
also helps to make sure that
properties such as link popularity are
consolidated to your preferred
version.
They explicitly state it will work cross-domain.
I have a customer that been on the web for some time. They have bought a domain name that describe it product, and a second one more up to date. Now that company has evolved to something more general and has bought a 3rd domain - something like:
vegetables.com (2005)
ecolo-vegetables.com (2006)
good-health-eating.com (2009)
Here are my questions:
What is the bet way to get all those domains under the new name?
The new name is unknown to search engine and other linker, I don't want to lose the ranking, so what is the best way to keep that ranking?
Can I point URLs to the "best" ranked domain?
What append to the backlinker? they link to which domain?
The new domain has a "-" in the name... which is really good to SEO but a little unnatural to type, should I get the no dash version too?
n.b. It make sense to redirect all the domain under the same, but will you choose the oldest (with modrewrite) or the newest but with no life under it's belt (so it doesn't exist anywhere in search engine)
another p.s. Some will tell me to redirect with .htaccess, but should I change the dns to point to the last .com. which solution is better
Are all three sites "Different" or do they point to the same website/content?
Use 301 Redirects to redirect your old domain names to the new domain names. If all domains are pointing to the same website, make sure you also use the Canonical Tag on all your pages.
If you 301 Redirect from the old domain names / urls, your rankings will be transfered to your new domain/pages. (the only exception to this may be any extra points you get from embedded keywords in your old domain names).
You should point old urls to your "new" urls/domain. Rankings and link juice should/will be transfered to the new urls/domain.
Ideally all your backlinks should update their links to the new domain, but it doesn't really matter. If the old domains are 301 redirecting to the new domain anyway, point to the old domain is just like pointing to the new domain.
Definitely get the no-dash version of the domain as well and just have it 301 redirect to the actual domain you want to target.
I'll give this a go.
1. You could possibly have redirects or just allow the DNS of the domain to point to the new (desired) website.
2. It's not hard to understand SEO (Search Engine Optimization) nowadays - ensuring you have the correct meta tags and other SE info will give you a big helping hand. There isn't any way of transferring SE ranks.
3. That's possible. You could have ABCDEF.COM at number 3 on google, but then set ABCDEF.COM to redirect to GHIJKL.COM.
4. If you set up redirects, and the new site has the same content as the old one, there is the possiblity of setting up your DNS and your redirect to redirect to the new version of the previous page on the new website.
( I don't think I worded that very well, hope you catch my drift )
5. Out of pure experience I'd say yes, get both. That way you can market to your customer audience as ABCDEF.com, but show to SEs as AB-CD-EF.COM.
Here is the best answer i got from this link
302 and 301 Redirects
When a request for a page or URL is
made by a browser, agent or spider,
the web server where the page is
hosted checks a file called
'.htaccess'. This file contains
instructions on how to handle specific
requests and also plays a key role in
security. The '.htaccess' file can be
modified so that it instructs
browsers, agents or spiders that the
page has either temporarily moved (302
redirect) or permanently moved (301
redirect). It is usually possible to
implement this redirect without
messing with the '.htaccess' file
directly, using your web host's
control panel instead.
From a search engine perspective, 301
redirects are the only acceptable way
to redirect URLs. In the case of
moved pages, search engines will index
only the new URL, but will transfer
link popularity from the old URL to
the new one so that search engine
rankings are not affected. The same
behavior occurs when additional
domains are set to point to the main
domain through a 301 redirect.
And the last word : from this link that just confirm what i know know !
First off, ensure you're using "301 redirects" rather than "302 redirects" or the link juice (PageRank) won't transfer to the destination URL. You can verify that 301s (not 302s) are in place by using a "server header checker" like this one. Only a 301 tells engines the previous URL has moved permanently and thus forwards the page's link equity to the new location.
