This tells the search engines that your website is important enough to be linked to and this validates the relevance of your content. Although you can personally approach other webmasters to request a link-back it is always preferable to generate quality content so that they link to your website voluntarily without your having to ask.
This is the ideal way of generating inbound links. Another way of marketing your web site is writing lots of free articles for other web sites and blogs, for, when they publish your articles and blog entries they link back to your web site.This brings me to the subject of blogs; your blog too can take you a long way on the path of Internet marketing. Just take care that when you design your blog it looks like the overall design of your web site.
Always remember that web site design and Internet marketing go hand in hand. If one is ignored the other automatically gets affected.
For instance if you carry out your Internet marketing campaign very successfully and when people visit your website and find it unconvincing in terms of your design they will leave it without doing any business with you.
