Crawl

Spot orphan pages in 5 minutes

Crawl your site with Screaming Frog, then compare the URL list to your XML sitemap and GA4 landing pages. Anything in the sitemap or GA4 but not in the crawl is orphaned. Add internal links from your top 10 pages.

Quick hits· Bite-sized updates
Content

Short-form video thumbnails in SERPs

Google is testing video thumbnails for pages that embed short-form content, even without a dedicated video schema. If you use Reels or Shorts embeds, expect more visibility experiments.

Google Ads

Performance Max gets negative keyword lists

After years of requests, Google finally added account-level negative keyword lists to PMax. Set these up before competitors start bidding on your branded terms.

Analytics

GA4 path exploration gets bulk export

You can now export up to 10,000 rows from path explorations in GA4. Previously capped at 500, this makes funnel and journey analysis actually useful for large sites.

AI Search

ChatGPT search adds follow-up suggestions

ChatGPT's search mode now suggests related follow-up queries based on your initial search. Optimizing for question clusters increases your chance of being cited in follow-ups.
