Title 51/60 Description 142/155

What to fix first

  1. high

    The title doesn't contain "balcony vegetable garden"

    Lead with the keyword, e.g. "Balcony Vegetable Garden for Beginners".

  2. high

    The post is too short to rank for a how-to query

    Add sections on watering, feeding and a month-by-month planting plan to reach 800+ words.

  3. medium

    The first sentence runs over 60 words

    Split it into two or three short sentences and use the keyword in the opening line.

60 or higher is easy for most readers. Below 40 is hard going for a general audience.

Keep titles under about 60 characters and descriptions between 120 and 155 so Google shows them in full.

No tool can. It fixes the on-page basics; links, competition and search intent matter too.
