Hey everyone. I will make it short:
My opinion is that I would rather not to write a description in inner page. The reason is - Google will choose the most proper description for the user who searched for "bla bla bla bla" (when my site will appear on the serps).
I think google might put my site lower in this query, just because of my static description is not suitable for what this user searched for (especially for long tail searches).
What do you think about it?
