1. Do's and Don'ts in link building<br />Incorporate your keywords in the anchor text<br />It is necessary to place your keywords in the text of your anchor text i.e. your link, because this link is used by other sites to send visitors across to your site. Though, it is a tedious process with directories until and unless your company name contains your keywords. With substantial increment in your keywords, you may contact everyone linking to your website with a personalized request with regard to the text used in your link.<br />For instance, you may happen to be selling stuff toys. Then your anchor text must say so – 'Stuff toys' or 'kids toys' or 'soft toys'. And not just a simple 'click here.' When evaluating from the search engine's standpoint, the company or product specific anchor text gives search engines your page's theme while the latter doesn't even provide any kind of hint. <br />Note: Your links will appear natural to search engines only if they are not similar. Manage links smartly; there should be slight yet easily noticeable disparity making them look as original as managed by their owned site. Since your company and product name can bring to you a host of opportunities. Perform every little task flawlessly to grab the attention of your customers and make it look natural to search engines, as per their point of view. This technique will make a huge difference in your future business prospects.

The nofollow link renders the link not needed for your rankings purposes because Google does not approve your page for that incoming link.<br />Daunt away from link farms<br />Refrain from using anything that turns up to look like a link farm or a web ring. These occur in situations when page groups link to each other and do not get any incoming links from outside trusted sites. As by linking to untrusted sites you stand at the edge of getting penalized. Therefore one must be careful as to whom they link to. To stay on the safer side and benefit, your core aim should be to get mass links possibly from trusted sites. If you are not penalized then the possible gain that you would have received from the link will be reduced because of its spam-like nature. As far as SE protocol is concerned, linking back to untrusted or suspected sites in order to build page relevancy is of nil profit and can be harmful.<br />Who you link to makes a difference<br />If, for instance, you get links from untrusted and off-topic sites then they won’t bring significant amount of increase in your rankings nor will blemish, rather may be of assistance.
