• SEO Foundation: Without solid technical SEO, other SEO efforts may not yield results.
Below is a deeper dive into our 9-Step Technical SEO Checklist:

Tools:
Steps:
1. Set up Google Search Console and add your website.

Ensuring crawlability and indexing is fundamental for search engines to discover and rank my website’s pages. I follow these steps to optimize this aspect using free tools:

Using the Robots.txt Report in Google Search Console, I verify that important pages aren’t blocked. I:
