To understand the need you must have to understand about content marketing. Content marketing is a marketing strategy that revolves around the creation, publication, and distribution of content to a target audience in order to bring new and quality traffic to your business. It is the way to keep your marketing strategy updated. Content Marketing is a bit different than other areas of marketing like social media and SEO. Without content, SEOs would have nothing to optimize for search engines.
Every email, every tweet, every landing page, and every product description need content. Content marketing is the use of that content to help meet a marketing goal for your organization. Now lets discuss about the need of content marketing in our businesses.

1. Build Trust With Website Visitors: The more content you create and share with your target audience, the clearer it becomes that you are an authority in your field. People trust experts and hire them to help solve problems.
2. Build Brand Awareness: Most people don’t know about your business and it’s time to change that. If done correctly, you can use content marketing to significantly increase traffic to you site so you can get consistent, quality traffic and inbound links to your site, and expose them to a brand they never knew existed. You’ll be able to generate more awareness and leads for your business through your content and show your expertise.
3. Generate Organic Traffic: When you are creating expert content for the sake of sharing useful and valuable information to your ideal target buyers rather than spammy sales copy, Google recognizes that your content is useful and provides the answer to people searching, therefore it will rank higher in the search results. If you keep your content up to date, informative, and relevant, it will rank higher and longer in the search engines.
4. Generate Leads For Your Business: Generating leads for your business is the reason any of us do any marketing at all. We need new leads to come to us and eventually buy what we are selling. Content marketing enables strangers to find you through your useful and informative content.
5. Convert Visitors Into Buyers: Don’t waste your content marketing effort by not leveraging it; instead generate leads throughout the buyer’s journey. The buyer’s journey consists of 3 main stages: awareness, consideration, and decision. Pay attention to how the content provided through each stage helps keep him traveling down the sales funnel.
