To have great content or massive content ?

Quantity or Quality Content

Writing great interesting content is a challenge and hard work.
Writing a lot of content pages is also a challenge and hard work.

The best is of course if you could create an overwhelming amount of great content but that is probably not feasible as it is too hard to achieve.

Creating quality content requires expertise, sufficient knowledge and experience which is not obvious.
Creating quantity content is easier as you will be able reusing available information from the internet.

best of both worlds?

Thus you need to make the choice between quality content and large number of content pages as both is unlikely to be created.
The massive content will attract more traffic than the qualitative content as it will pop-up in more searches. However the conversion rate will be lesser than of the qualitative content.
The qualitative content might fail to drive enough traffic but have a high conversion rate.

The best probably to have a few pages of quality content supported by massive number of pages with lesser content in order to generate more traffic.

Attention span

One more important problem for your creativity is the content needs not only to be interesting but also not boring. You can have the most interesting content but when it is difficult to read or being presented like a math course then it is likely your content will not retain the attention of your audience.

Is your content qualitative or quantitative ?
