Most businesses don’t like to use subdomains because they feel like they give them a disadvantage in search engine marketing, such as having a prefix name before your web-site, being ignored by bots and index spiders in search engines and all in all, it just doesn’t look right. So let's find out the facts on sub domains.

A subdomain is substitute or second-level of a domain. A normal domain name looks as this: www.jamesbrown.com . A subdomain is similar with this

http://bravenet.jamesbrown.com. Subdomains do not have www on the front of them. All subs start with “http://subdomain/maindomain.com pattern of identification.

Sub domains search engine ranking well. Search engine spiders and bots are not prejudiced when it comes to the ranking of subdomains and regular domains. As long as your site has the right SEO keywords and has been optimized, whether you have a subdomain or regular domain name doesn’t make a difference at all.

Let’t pretend that you web hosting site has a lot of categories in it. If you were to submit to a search engine, you could submit each subdomain as its own individual category and still get a good ranking.  Each subdomain would be looked at by search engines as a new site with its own index or home page. You may want to try to make sub folders on the subdomain so that search engines can find the folder as one set of site information.

People worry about their subdomain getting banned if the main domain name is banned. If the main domain is banned, it will have an effect on the subdomain. You see this happen often in adult content sites that have violated certain agreements that they have signed with a provider that does not want a domain used for adult material.

Again, there is nothing wrong with using a subdomain. If you want to build every sub domain as its own, then just do so.If not, find a main domain and use that as a certified landingpage.

People often complain in search engine marketing forums that their websites have been expelled from Google and they do not have any idea why their website is not present in Google. Here are some advices from search engine expert that a seo web desgin site will not apply.

Check search results of Google. Just Check the Google toolbar. You can put a URL in the box of Google search and click search button. If no message is available for the given web address, it mean that the URL does not be in the Google database. If you look a new site, you will must find the sign because the site has not been cached.

Viewing Google Toolbar is yet another way of checking whether the website has been banned.

The moment the Google Toolbar is installed, just visit your website. If you meet the Google Toolbar color is gray, which indicats that site have been clocked by Google.

What can cause your website to get banned? 

There are both onpage ranking factors and offpage ranking factors that can lead Google to ban your site.

Hidden Text

Hidden Texts are those which the users cannot see while visiting your webpage. This is frequently choosed by the web masters since they can put keywords or phase in the whole webpage without it interrupting with what the people actually see.

Alt image tag spamming

This is yet another method to stuff keywords in the website, allowing the search engines to check the keywords, but preventing the visitors to notice any difference within the website.

Meta Tag Stuffing

There is no necessity of using thousands of same exact keywords into the Meta tags. Google search engine does not check Meta Tags while calculating the ranking of web sites. This may lead Google to punish you. So it is best to stay away from them.

Title Tag Stuffing

In the title tag, just use the keyword for once since if you overdo the keyword, the site may be banned from the search engines.
