What On-Page or Technical SEO Factors Could I Be Missing?

Hi everyone,

I’m trying to understand why a specific e-commerce page is ranking first in the SERPs for a keyword with low difficulty (KD 12) and about 6,000 monthly searches, despite my competitors and I analyzing many core SEO aspects.

What I’ve Compared So Far:​

I’ve created a table comparing the top 5 ranking pages and analyzed the following:

• Titles, Meta Descriptions, H1/H2 Optimization
• Videos, Backlinks, Content Amount (words), Keyword Density
• PageSpeed Insights (Mobile) and ALT Images

The first-ranking page seems not fully optimized in several areas:

• Missing H1, no videos, zero backlinks, and lower content.

Yet, it still outperforms others.

My Question:​

What additional on-page or technical SEO concepts could I analyze or add to my list to better understand why this page holds the first position? Could it be factors like user signals, crawl efficiency, or other hidden aspects?

I’d appreciate your input and suggestions to uncover what might be influencing this page’s ranking.

Thanks in advance!

After on-Site SEO, it is backlinks and site age
sometimes backlinks are not shown in analysis tool.
You should also check age of product page, product category page, last update date, frequency of update
