You can implement a highly proactive social media campaign and give due thought and attention to your SEO but search engines can also measure elements such as trust, spam, and authority by reference to the number and quality of inbound links to your site and these will affect your search result rankings.
For search engines that crawl the web, links are a major factor in determining what pages are important, popular and how they should be ranked in search engine results, so if you want a successful online presence, make sure you don’t leave out those all important links.

The fine details of the way in which a search engine analyses a link are complex, intricate and to some extent unknown but to maximize the success of your internet marketing you really need to give serious attention to link building packages.
Focus your energy on gaining inbound links from the wrong source could be doing your website more harm than good as could paying for links. Building links from topic-specific and or highly regarded, relevant sources is both a subtle skill and very time-consuming and all that must, of course, come hand in hand with fresh, updated content and regular link usage.
Link building experts rely on years of experience as well as careful analysis of the quality and ranking of the pages from which a link comes and the quality and source of links from successful competitors, in addition to a thorough understanding of a website analytics and search engine algorithms.
Get your link building packages right and you should see increases in search traffic, higher rankings, more frequent search engine crawling and increases in referring link traffic – that, after all, is half the battle won.
