AutoLink On Certain Words, Good or Bad?

Making automatic links on certain words, I saw the first time in wordpress. But it can also be applied on blogspot. In the article named Squire Blog SEO Smart Links (Please read: Put SEO Smart Link To Blogger / Blogspot). Granting automatic link these votes can improve SEO performance. Really? There are some views and tips below ... 
AutoLink installation On Specific Words To put it very easily. Please open: Scripts Smart Link, and copy all the code, then put it on the </ body>
Settings: Here is the final piece of the smart script links, there are some parts that you need to change. </ Script>
<script type='text/javascript'>
var f = new autoLink ();
f.add ("SEO", "http://blogjuragan.blogspot.com/");
f.startScript ();
</ Script> </ b: if>

- The word SEO replace certain words that will be given a link automatically. When I try this script is not case sensitive. That is the word SEO, SEO, SEO, SEO, seo or a combination of capital letters and not still be considered the same and will automatically be changed according to the words that we put into the script. - At the second red, please replace the link address you want. - Certain words that we specify, if acting as the first word on the post, will not be given a link automatically. 
Effect ... After you install the script in your template, then any specific word on your blog (for example in the script above are the words: SEO) it will automatically become a link to the address you specify as well. 
Why You Want to Use? Of course this is very easy because all of a certain word can be the link that you want without having to edit them one by one. This will strengthen the link word is keyword density (read: Optimize Keyword Density) 
Why You Do not Want to Use? Although some people think is good for SEO, I personally choose not to use it. To pursue keyword density link, I chose to give a link on a particular word manually as needed. Use the script above can also be disturbing because we limit the time to write posts. To avoid too many links on the post, then you have to minimize certain words that have been selected. For example, you define the word SEO is given effect links automatically. This means that when you post, you are required to not use many words SEO. The use of the word SEO is too much, and automatically leads to a goal (link) is not good because it leads to spam, especially with a lot of the same anchor (should read also: Prompts Google To Many Links Each page) 
Dangerous in the future as well when you lose this script, whether intentionally or not.All the words SEO will lead to a particular link. Of course if we post a lot, then this will amount to very large. If the script is suddenly removed? Happened missing link on a large scale as well. 
If You Stay put If you are interested and still want to install it, I have some tips for you. - Specify only one word that was given this automatic effect. - Do not vote for a word that often appears. - When you post, double-check the number of words and make sure that not too much .. Try less than 10. - In my opinion this is more suited for dummies blogs you with smart direct link to the main blog. 
It is very interesting, whether you want to use it or not? It's your choice. Good morning and hopefully useful ...
