The URL redirection service is also popular as URL redirect, URL redirecting, URL forwarding, domain redirection and domain forwarding. In all of the cases it refers to one and the same web technique for pointing a web page to another URL of your choice.

Types of URL Redirection.

Depending on the type of URL update you need to make for domains or subdomains of yours, you could take advantage of 4 basic types of URL Redirection:
• Permanent redirection: 301 – this URL redirection is used in cases when the URL for a certain website/web page has been changed for a long-term period. Its main purpose is to automatically redirect any references to the outdated URL of a certain page to its new web address. Through the 301 redirect website owners can preserve the relevance of any existing external links to their store.
• Temporary redirection: 302 – you will need a 302 redirection in cases when a certain URL has been changed to a different address temporarily. The 302 redirect tells anyone trying to access a certain URL that it is temporarily unavailable and automatically send them to a new valid address. With the 302 redirection set, the owner asks users to continue using the new address until modified at a later time.

What is Black Hat SEO>

The term black hat SEO refers to using deceptive or unethical techniques that do not follow the search engine guidelines, in order to get high rankings in search engines. The following methods are generally adopted for black hat SEO purposes.

• Black Hat SEO Techniques to Avoid
  Hidden Text - Adding unwanted text and making it invisible by setting the same color and background, using tiny fonts, hiding through CSS code such as using "display: none" or putting it in "no script" or "no frame" sections etc.
  Keyword Stuffing - Addition of keywords on calculated places within the body of the page to increase its keyword density, frequency and diversity. This is useful to make a page appear to be more relevant to a web spider for those specific keywords.
  Meta Tag Stuffing - Adding repeated keywords in the meta tags just for the intention of raising its relevancy.
  Doorway Pages - These are generally irrelevant, low in quality, non informative or as to say "fake" pages that are only designed to attract web spiders. A doorway page will generally have "click here to enter" on the page.
  URL Redirection - Taking the visitor to another site without their intention or knowledge. e.g. using JavaScript, server side redirection or HTML redirection using Meta Refresh tags.
  Link Farms- A group of web sites that all hyperlink to every other site in the group.
  Cloaking- It means to serve different contents of a web page to the search-engine spider and to the human visitors.
  Mirror Websites- Hosting multiple websites with almost similar contents but different urls.

For long terms gain and getting permanent stable position in search engine results, all or everything that seems like black hat SEO should be avoided.
