The Last Reviews Update Is Complete

After a 29-day rollout, Google announced that the last reviews update finished on December 7, 2023. From now on, the reviews system will be updated on an ongoing basis.

This system is meant to reward product and service reviews that feature original research and helpful content. If your website features reviews and was hit by this update, it may recover over time if you improve your content quality.

The update overlapped with the November 2023 Core Update and contributed to SERP ranking volatility through most of November and early December.

Google Introduces Gemini

In an important piece of December 2023 SEO news, on December 6, 2023, Google announced Gemini, its most powerful AI model to date. Users can see it in action now with Bard and soon in the Search Generative Experience (SGE) lab.

Gemini can understand text, image, video, and audio inputs in a more advanced way than previous AI models. It also can pause and “think” through an answer instead of giving its first impression, which makes its responses to prompts more accurate.

Gemini will be available in three versions: Ultra, Pro, and Nano.

Ultra is the “largest and most capable” version that can work on highly complex problems. Pro is made to work across a wide variety of tasks, and it is the version now implemented in Bard.

In 2024, Gemini Ultra will be accessible through Bard Advanced. This technology has the potential to be world-changing, and we highly recommend you watch the short video embedded in Google’s blog post announcing it.

New Robots.txt Report in GSC

Google released a new report in Google Search Console for robots.txt, which shows when the file was last crawled and any issues found.

The old robots.txt tester tool will soon be sunset. To find the new report, go to Settings > Robots.txt > Open Report.

If you’re looking for which pages are being blocked via robots.txt, you can see that information in the Page Indexing section of GSC.

Missing the old tool? Bing still has one, and a variety of other companies have built their own.

Video Mode Changes

Google changed their guidelines for how they index pages with videos.

Previously, a blog post with a video, a PDP with a related video, or a video category page displaying multiple videos could have each been eligible to appear. Now, a video on a page must be the “main content,” or else it won’t be shown in Video mode (the video tab on Google).

If your site has lots of videos, you may need to rework those pages so that videos are considered the main content. You should also have a valid video URL, use a supported video format, contain the video within the viewport, and make sure it’s not too small or too tall for the viewport.

Bing Chat Becomes Copilot and Gets Upgrades

On November 15, Microsoft announced the rebranding of Bing Chat and Bing Chat Enterprise to Copilot.

For easy access, go to At the time of this writing, still works, but Jordi Ribas of Microsoft said on X that they will eventually merge the user experience of the two.

Just three weeks later, in a post celebrating Bing Chat’s one-year anniversary, Microsoft announced several upgrades coming to Copilot:

  • GPT-4 Turbo: The latest model of ChatGPT will allow Copilot users to complete more complex tasks.
  • New DALL-E 3 Model: This image generation model uses your prompts to create higher-quality and more accurate images than older models.
  • Inline Compose with rewrite menu: Microsoft Edge users will be able to highlight text on a web page and ask Copilot to rewrite it.
  • Multi-Modal with Search Grounding: Combining GPT-4 with vision and Bing image search and web data, users should get better results when using image search.
  • Code Interpreter: Microsoft is developing and testing “a new capability that will enable you to perform complex tasks such as more accurate calculations, coding, data analysis, visualization, math and more.”
  • Deep Search: Harnessing the power of GPT-4, “Deep Search expands search queries into more comprehensive descriptions to deliver more relevant results.”

Google Bard Can Understand Some Videos

If you use Bard within a personal Gmail account and with the YouTube Extension, you can now have conversations about YouTube videos with the AI assistant.

Bard can understand the spoken word in videos and answer questions about them. In Google’s example of recipe videos for how to make an olive oil cake, you can ask Bard how many eggs are used in a video, and it can answer accurately.

According to Google, the goal of this new technology is to give users deeper engagement with videos.

Google Is Cracking Down on Parasite SEO

If you’ve never heard of parasite SEO, you probably will soon.

Parasite SEO is basically defined as content that’s hosted on a third-party site for the purpose of the content producer’s own site to rank better. There are two types of parasite SEO; one is done intentionally with the permission of the host site and the other is done by hackers. Neither type is good for SEO because even the intentional version is a “black-hat SEO” practice.

In several threads on X, Google claimed that it’s cracking down on parasite SEO (a name it does not use internally, by the way). Google will consider content on a website that’s outside the main purpose of the site and appears to be created independently of the website to be parasite SEO.

The goal is to use the Helpful Content System to recognize and penalize those websites. However, that process is not quite ready yet.

In the meantime, if you’re a victim of parasite SEO created by hackers, there are some things you can do about it:

  • Double-check access to your DNS and be ready to change the password. A hacker with access can set up a subdomain or subfolder and start creating content, and it could take a while before you realize it has happened.
  • Ensure your CMS/ecommerce platform is up to date. As platforms recognize weak spots in their security, they may add patches or fixes to prevent a hacker from attempting parasite SEO.
  • Investigate and take immediate action if you notice an unexpected, sudden surge in the number of pages indexed for your site in Google Search Console. It could be a sign that your site has been hacked.

Your site will suffer in the SERP rankings if Google thinks you are practicing parasite SEO. You’ll have to work to prove to Google that your website deserves a second chance, so it’s a good idea to stay vigilant.
