★★ Is it really necessary to eliminate all duplicate content or should you rely on rel=canonical?

★★★ Should you still invest in AMP to optimize speed and ranking?

Speed is a ranking factor, but AMP is not necessary for having fast pages. You can create very fast non-AMP pages and slow AMP pages. What matters is the actual measured performance, not the AMP forma...

★★ Is it really necessary to nofollow site-wide links to your legal pages to optimize PageRank?

Having 10 links instead of just one to a legal page (privacy, contact) on every page of the site probably wouldn't change anything. Google understands that these pages are linked everywhere without be...

★★★ Does Google really track HTML links that are hidden by JavaScript?

If an HTML link exists in the code but a JavaScript event captures the click (for example, to display a dropdown menu instead of navigating), Google can still see and follow that HTML link. The <a> el...

★★★ Do Hn Tags (H1-H6) Really Impact Google Rankings?

★★ Is Google really tolerant of hreflang errors that mismatch language and content?

If a Japanese page (e.g., /jp) declares in its hreflang x-default or hreflang that it is in English while the content is in Japanese, this creates an inconsistency. Although this needs to be corrected...
