How to Use SEO Addons in Your Chrome Browser Efficiently

We all enjoy free tools, but having too many for your browser is like running a marathon in flip-flops — not pretty. 

This is how we use multiple SEO addons in Chrome:

• Pick 3 to 5 core tools that you’ll use daily.
• Turn off the rest until needed.
• Because Tools:
  • SEO Extension + Meta SEO Inspector = On-page optimization
  • SEO Minion + NoFollow Simple = Link audits
  • Keyword Surfer + TextOptimizer = Content creation process

Also, be sure to clear the cache and update Chrome regularly. It is amazing how much lagging quality is due to an outdated addon versus your available RAM.
