Google ships algorithm updates constantly, but the ones that actually move local rankings tend to fall into a few recognizable categories. Here's what each one actually targets, and what we check on a client's site after each one lands.
Core updates
Google's broad "core updates" happen several times a year and re-evaluate overall page and site quality rather than targeting one specific tactic. A site that loses rankings in a core update usually has an underlying content-quality problem that was already there — the update just changed how much weight Google gives it. The fix is rarely a quick technical patch; it's usually a genuine content-quality pass.
The Helpful Content signal
Google's helpful-content guidance specifically targets pages written primarily to rank rather than to answer a real question — thin, generic, keyword-driven content is exactly what it's built to demote. This is the single biggest reason we push clients away from mass-produced, templated blog content: it's now a liability, not just a missed opportunity.
Local-specific signals move independently of core updates
Your Google Business Profile completeness, review count and recency, and citation consistency (the same name/address/phone appearing the same way across directories) all affect map-pack rankings on their own timeline, separate from the broad core updates. A business can lose local visibility purely from letting its GBP go stale, with no core update involved at all.
What we check after every major update
- Rankings for your top 10-20 target keywords, tracked before and after — not a gut feeling, actual position data.
- Whether the content on underperforming pages actually answers the search intent, or was written to hit a keyword count.
- Google Business Profile completeness and recent review activity for local clients.
- Core Web Vitals and mobile page speed, since these are baked into ranking and drift over time as sites get new plugins and content added.
The practical takeaway
You can't out-guess individual algorithm updates, and chasing every one with a tactical fix is a losing game. What holds up across updates is the boring stuff: genuinely useful content, a complete and active Google Business Profile, a fast site, and real (not purchased) reviews and links. Businesses that already have those in place tend to barely notice most updates.
