The SEO Blogs Actually Worth Reading

Most "best SEO blogs" lists are affiliate padding. This one is short on purpose: these are the sources I actually check, and the reason each is worth your time.

Primary sources — start here

• Google Search Central Blog — the only source that isn't interpretation. Algorithm updates, documentation changes, and policy clarifications come from here first. If a claim contradicts this, the claim is wrong.
• web.dev — Google's performance and Core Web Vitals resource. The authoritative source on LCP, INP, and CLS.

Industry publications

• Search Engine Land — fastest reliable reporting on algorithm updates and industry news.
• Search Engine Journal — broad coverage, heavier volume, useful for tracking what the industry is discussing.

Tool company blogs

These have a commercial interest, but they also run large-scale studies nobody else can afford:

• Ahrefs Blog — strong on data-backed studies and technical explainers. Their free SEO course is genuinely good.
• Moz Blog — the Whiteboard Friday archive is one of the better structured learning resources in the field.
• Semrush Blog — covers SEO alongside PPC and content, useful if you work across channels.

How to read SEO content critically

The field is full of confident claims with no evidence behind them. A few filters that save time:

• Check the date. SEO advice ages badly. Anything about FID instead of INP, or meta keywords, predates current reality.
• Look for the source. Does the post cite Google documentation, a study with a sample size, or nothing at all?
• Be suspicious of certainty. Google confirms very little. Anyone stating exact ranking-factor weights is guessing.
• Watch for correlation dressed as causation. "Top-ranking pages average 1,890 words" does not mean writing 1,890 words causes ranking.
