How to Choose the Right SEO Chrome Extension
Before installing every shiny extension, ask:
- Does it integrate with your current SEO tools?
- Does it provide data you can act on, not just admire?
- Will it slow down your browser or workflows?
For best results, combine two or three extensions that complement each other — for example, Ahrefs SEO Toolbar for backlinks, Keywords Everywhere for research, and Check My Links for maintenance.
