Title too short or too long
Effort to fix: Quick win (under an hour)
Why it matters
Very short titles waste the most prominent spot in search results; very long ones get cut off mid-word.
How to fix it
Rewrite the title to about 30-60 characters: what you do and for whom, then the brand.
On WordPress
Edit the SEO title field for the homepage in your SEO plugin rather than the site name.
