5 Google SEO Algorithms
1. Core Web Vitals Algorithm
This algorithm measures how users experience a webpage, not just what the page says.
It focuses on:
How fast the main content loads
How quickly users can interact with the page
How stable the layout is while loading
Why it matters:
Even great content can rank lower if the page is slow or unstable.
Student takeaway:
SEO is no longer just content and keywords—performance matters.
2. Mobile-First Indexing
Google now judges your website mainly by its mobile version.
If your site:
Loads slowly on phones
Has unreadable text
Misses important content on mobile
…your rankings can drop, even if the desktop site looks perfect.
Why it matters:
Most searches today happen on mobile devices.
Student takeaway:
Always think mobile before desktop when doing SEO.
3. E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)
This system evaluates how trustworthy and credible content is.
Google checks:
Does the writer have real experience?
Is the information accurate and reliable?
Can users trust this website or brand?
This is especially important for business, finance, health, and education content.
Why it matters:
Low-trust content struggles to rank, even with good keywords.
Student takeaway:
SEO rewards real knowledge and transparency, not anonymous content.
4. Freshness Algorithm
Some searches require up-to-date information, and this algorithm handles that.
It prioritizes:
Recently published content
Updated older pages
Timely information for trending topics
Outdated content may lose rankings even if it once performed well.
Why it matters:
Search engines want to give users the most current answers.
Student takeaway:
SEO is ongoing—updating content is as important as creating it
5. Google Pigeon Algorithm (Local SEO)
The Google Pigeon algorithm improves local search accuracy.
It helps Google decide:
Which nearby businesses to show
Which locations are most relevant to the searcher
It connects local listings with traditional search signals.
Why it matters:
Local businesses depend heavily on search visibility.
Student takeaway:
Local SEO requires consistency in business details and location signals.
