If I own an online shopping mall using blog, do you think that I need to update or insert contents from time to time or I just concentrate on driving the traffic? Any idea? Please comment. Thanks
You better do both. Content is a way to attract people come to your site. So, you can concentrate on how unique, value of your content, then you do drive traffic.
Be active and update your blog! Provide useful information and play around with the keywords! Best of luck.
Use the content you post to your blog to draw people in over and over again from various social media sites like Twitter, FB, etc. People usually don't buy a product on their first visit to a website, getting them to come over and over again builds trust and creates repeat traffic that leads to sales. So yes, add content and use the blog to draw traffic to your site.
You need to do everything for positive results. Content should be unique and with that you can do Organic SEO.
Updating the content would be my first priority, everything else will come in time. When people land on a site that has not been updated for sometime, thye usually hit the back button.
