Search engines want websites to have a level playing field, and look for natural links built slowly over time. While it is fairly easy to manipulate links on a web page to try to achieve a higher ranking, it is a lot harder to influence a search engine with external backlinks from other websites. This is also a reason why backlinks factor in so highly into a search engine's algorithm. Lately, however, a search engine's criteria for quality inbound links has gotten even tougher, thanks to unscrupulous webmasters trying to achieve these inbound links by deceptive or sneaky techniques, such as with hidden links, or automatically generated pages whose sole purpose is to provide inbound links to websites. These pages are called link farms, and they are not only disregarded by search engines, but linking to a link farm could get your site banned entirely.
Two other practical limitations can be seen in the case of digital marketing. One,digital marketing is useful for specific categories of products,meaning only consumer goods can be propagated through digital channels.Industrial goods and pharmaceutical products can not be marketed through digital channels. Secondly, digital marketing disseminates only the information to the prospects most of whom do not have the purchasing authority/power. And hence the reflection of digital marketing into real sales volume is skeptical.[citation needed]

What are "backlinks"? Backlinks are links that are directed towards your website. Also knows as Inbound links (IBL's). The number of backlinks is an indication of the popularity or importance of that website. Backlinks are important for SEO because some search engines, especially Google, will give more credit to websites that have a good number of quality backlinks, and consider those websites more relevant than others in their results pages for a search query.

Make it as easy as possible for users to go from general content to the more specific content they want on your site. Add navigation pages when it makes sense and effectively work these into your internal link structure. Make sure all of the pages on your site are reachable through links, and that they don't require an internal "search" functionality to be found. Link to related pages, where appropriate, to allow users to discover similar content. Denver Page Rank Click Here
