How important is a blog

We have made products and we sell our products on affiliate sites and our own sites. More people told me that a blog is very important for a website to be successful and to get more traffic although it needs more efforts on update content daily or maintain it. what do you guys here think about your blog you're owning. Is it important for you or not? why?

Here are 4 reasons you need to blog:
* Drive traffic to your website
* Increase your SEO/ SERP
* Position your brand as an industry leader
* Develop better customer relationships

Blogging is really important, it keeps you engaged with your audience and you get to see what they like or don't like. It makes you an authority in your niche and can help you grow your social media profiles by offering free content on a daily bases.

It's much easier for someone to become a customer if they joined your emails list via a blog post they found useful. It will help you get a lot of free traffic from search engines and social media sites.

A blog makes it easier for people to share your content and brand online. It also builds trust and makes it easier to connect with industry leaders in your niche.

Once the blog is popular it can help you increase revenue by placing ads on the blog, offering sponsored reviews, paid guest posts etc.

A blog has a lot of benefits, the hard work involved does pay out good when the blog is popular.

A blog is only as important as its content. I find reading company blogs rather interesting, and it allows me to gain insight into how they think and do business - but unless they actually post valuable content on a regular basis, it's worthless.

Blogs are great because you can learn so much and share so much information on them. Interested readers will continue to come back, which is always a good sign.
