Maintain consistency in words/phrases used in one blog (eg If you’ve used NumPy in one part of the copy, use NumPy everywhere, not numpy or Numpy). Here are some other spellings that consistency should be maintained on:

  • Python — not python
  • PyTorch — not pytorch
  • GANs — not gans
  • Kaggle — not kaggle
  • CUDA — not cuda
  • Tensor
  • Deep Learning


Smileys are used at some places and not others — a call can be taken if that is the kind of tone the company would prefer.


Your blog title should be catchy, but should never include a full stop.
It should never be written in capital letters.


Your blogs can have an informal or formal tone, depending on what you are comfortable with. However, maintain consistency in your tone and avoid the following:

  • Do not use colloquial language suddenly in the blog if it has not been used elsewhere
  • Have a proper introduction and conclusion to your blog
  • Include your social media links towards the end of your blog so your followers can find you there as well
  • Try to have a catchy title or headline for your blog
  • Try to add a subheading for your blog, so people get an idea of what it is about
  • Include pictures, if possible and mention the source of where you sourced the image from
