Recently, a leaked document has come to light, revealing over 14,000 attributes that Google considers when ranking websites.

Published in March, this document provides some unexpected insights compared to what Google has publicly shared about its algorithm.

In this blog post, we will break down the key takeaways and explore how they can impact your SEO strategy.

Site Authority Score

One of the most significant revelations is that Google does assign a “Site Authority” score, despite previously denying it. Similar to Moz’s domain authority, this score is heavily influenced by your site’s backlink profile.

This finding underscores the importance of link building as a crucial component of a solid SEO strategy.

Ensuring your website earns high-quality backlinks can boost your site’s authority and improve its ranking.

User and Chrome Data Analysis

Google utilises various click data and user behavior from Chrome to determine search rankings.

This means that providing a great user experience on your website is more important than ever.

Ensure your site performs well in Google Chrome on both desktop and mobile devices.

Consider factors such as load speed, mobile responsiveness, and overall usability to keep visitors engaged and improve your rankings.

Page Version Considerations

Interestingly, Google only considers the last 20 versions of a page in their algorithm.

If an update negatively impacts your rankings, it may require multiple changes to recover.

This finding highlights the importance of continuous optimisation and monitoring of your website’s performance.

Regularly updating your content and making necessary adjustments can help maintain and improve your rankings over time.

Homepage Influence on PageRank

Google uses the PageRank score of your homepage to influence the ranking of every page on your site.

A strong homepage can significantly boost your entire site’s performance.

Investing time and effort into optimising your homepage is essential.

Ensure it is well-designed, informative, and includes relevant keywords to enhance its PageRank and positively impact your overall site ranking.

Font Size and Weight

Another interesting discovery is that Google scores pages based on the font weight and size of terms.

To meet accessibility standards, your font size should be at least 16 pixels.

This consideration likely aims to enhance user experience and accessibility.

Ensuring your content is easily readable not only benefits your SEO but also improves the overall user experience.

Importance of Page Titles

Google evaluates how well your page title matches the search term with a “titlematchScore.”

This finding reinforces the critical role of having a strong, relevant page title for SEO.

Crafting compelling and keyword-rich page titles can significantly improve your chances of ranking higher in search results.

Ensure your titles accurately reflect the content of your pages and include relevant keywords.
