One Way Linking - Two Way Linking - Three Way Linking

One way linking:
Getting link back to you site from another site is called one way linking, in which you are only putting link in other site, but not receiving that site link on your webpage.

For example:
Your site -- www.abc.com
Other site -- www.xyz.com

In one way linking, abc.com will place its link in xyz.com, and it will give you backlink. www.abc.com --> www.xyz.com

Two way linking:
Two way linking also called reciprocal linking, in which you have to give link back to all those site from which are getting link back.

For example:
Your site – www.abc.com
Other site – www.xyz.com

In two way linking, abc.com place its link in xyz.com and same way xyz.com place its link in abc.com. It like give and take relationship

www.abc.com --> www.xyz.com
www.abc.com <-- www.xyz.com    

Three way linking:
The webmasters who own multiple sites are basically involved in three way linking. They used to get link back through his own websites.

For example: One has 3 websites.
www.site1.com
www.site2.com
www.site3.com

Now site1 place its link on site2, site2 place its link on site3, site3 place its link on site1. This technique is called three way linking.

Why one way linking?
One way linking is most preferable and ethical technique. I strongly recommend going for one way linking program rather than two ways or three way linking.

Advantages of one way linking

1. The most easy to create one way link.
2. Less time consuming.
3. More effective rather than two way or three way linking.
4. Ethical way of link building.

Why not two linking?

1. Two way linking (link exchange) have few disadvantages as listed below.
2. Search engine can easily identify link exchanged links, they give high preference to two way links.
3. Its not sure how long you link will be visible on other website, they can remove it any time without information.
4. You can’t control the placement of your reciprocal link, other site can place your link anywhere in their whole site.
5. Reciprocal link might be coming from the page which itself contains thousand of out going links which reduce the quality of your back link from that site.
6. Links to other website on your website, directs traffic to other sites from your site.

Why not three way linking?
Most people appealing in 3 way linking are doing it with the express goal to control search results. This usually means they are trying to make automated bots think their ideas are better than they are, and are willing to do deceptive things to do it.

There are legitimate reasons to do three way links, but most of the three way link partnerships I have been offered are not worth.

The real problem is that if their two sites are not connected and they are primarily working to benefit the link popularity of their main site then it does not really hurt them if the site linking to you gets banned. If those sites get banned then they parse no link popularity to you.

In doing this webmasters can agressively market their high margin websites while keeping them somewhat shielded from the dangerous effects of their aggressive promotion.

In fact many marketers might set up 20 or 30 or more secondary sites to change links with.

Bad SEO Techniques

We all know there is no use of site if no body aware about it. That is why SEO comes in picture. It is obvious site get more hits which comes higher in search engine rank than those sites which are several pages back. There are few techniques to focus on for getting higher position in search engine. Few of them are not good as per search engine algorithms, which we called “Bad SEO Techniques” as listed below.

• Hidden Text.
  The text which has same color as the background is considered as the hidden text. The user can not able to see that kind of text but the bot can see it. One should not stuff excess keywords in such a way, this considered as bad technique.
  

• Link Buying.
  Buying a link is one of the most popular techniques. Because of its immediate result people attracts to follow it. But believe me, it’s very costly and at the end it’s not preferable. Google detects purchase links posted under “sponsors links” label, Google mark those links and considered them useless links.
  
  
• Cloaking.
  Cloaking is a technique in which spider can see different contents than user. Search engines don’t like if some one tries to fool them. Site might get banned if it follows cloaking.
  
  
• Duplicate Contents.
  Search engine robots don’t like to go through same contents 50-100 times. They would like to crawl different content every time they crawl any of web page. When robot detects duplicate content, any one of all those can be indexed. Other pages won’t get ranked.
  
  
• Link Exchange.
  Robots really hate exchanging links. In early days, people used to follow this technique, and even today few people are still following it. It’s also known as reciprocal linking and two way linking. It won’t hurt site or wont banned site, but it won’t give any benefit either.
  
  
• Keyword Stuffing.
  On-page optimization is one of the most important factors. Avoid use of excessive keywords in your site to get high rank in SERP. If your site is stuff with keywords, then it would not be appreciated by users as well as robots. It won’t ban site, but it affects users trust rank.
  
  
• Link Farms.
  Don’t go for this technique at all. Say bye to link farming technique for ever. Google knows who follow this technique, if they are not found yet, they will be caught soon. The site may get penalized or may get banned. It will hurt page rank badly.
  
  
• Use of Session IDs in URL.
  Search engines prefer static web pages. When there is session ID at the end of URL, search engine considers that page as different page when it crawls again that same page. And none of the version of the page will get ranked. If you want to boost page rank of your site, avoid using session ID.
  
  
• Flash Implementation.
  Falsh makes your site very attractive, but using flash on site is useless and page rank killing technique according to search engine algorithms. Search engine loves text the most.
  
  
• Use of Scripting.
  Any of the scripting language is widely use in many of the websites. Some times it’s highly required to use scripting, but the problem is, robots don’t know how to read scripts. So the links put under scripting will never get chance to get indexed or crawl.
  
  
• Doorway Page Generation.
  Doorway pages are mainly designed for search engines not for users. It’s also known as portal pages, jump pages, entry pages, gateway pages etc. When user clicks on doorway page, it immediately redirects to another targeted web page, which is created for users.
  
  

Above all are bad search engine optimization techniques. Stay away to get long life ranking results on search engine result page.
