Questions this episode answers

What were the major Google algorithm updates in 2021?

By August 2021 there were nine updates including passage ranking in February, a product reviews update in April, a page experience update on June 15th, two spam updates in late June, and a broad core update in July. Each targeted a different aspect of quality, speed, or link integrity.

How does the 2021 page experience update affect websites?

The page experience update, which began rolling out June 15th, is primarily a speed update tied to Core Web Vitals. Google confirmed gradual rollout to avoid sudden ranking drops. Site owners should check Search Console, reduce JavaScript, limit heavy plugins, and consider server-side caching.

What should product review pages do to rank well after the April 2021 update?

Google designed the product reviews update to reward in-depth research over thin content. Reviews should show physical use of the product, provide quantitative measurements, compare competitors, discuss benefits and drawbacks, describe product evolution, and go beyond what the manufacturer says.

How is Google's spam update affecting link building strategies?

The June 2021 spam updates targeted link schemes and low-quality links. Google is algorithmically de-indexing low-quality pages, which removes associated link juice. Sites relying heavily on mass link building saw ranking changes, with sponsored, guest, and affiliate content most likely to be impacted.

In their words

Google has said that some sites may lose positions, not because they did something bad, but because the algorithm's judgment of what is relevant has changed.

Host

Google warned that any sites taking part in link spam tactics could see rankings change with sponsored guest and affiliate content most likely to be impacted.
