Technical SEO field notes from the DeepSpider team.
Every Japanese SEO guide gives a different character count. Google cuts titles by width, not by count. What that means for full-width text, and how to write titles that survive the cut.
Read article →Google ignores Crawl-delay, Yandex stopped reading it in 2018 and Search Console no longer has a crawl rate setting. So who still pays for the line? Bing, AI crawlers and your own SEO tools.
Read article →Japanese visitors read the small print. These checks look at what they notice: the page language, No.1 claims, tax-inclusive prices, the external transmission notice and clinic advertising, plus five general checks that matter more on Japanese sites.
Read article →Most audits check the same broken links and missing titles. These four checks look between the pages: “best” lists that crown their own author, titles that promise what the page doesn’t show, links that lead to the wrong page and copied location pages.
Read article →Google doesn't treat translated pages as spam because a machine helped, but many low-value translations can count as scaled content abuse. Here's what Google says, what happened to Reddit's AI translations, what makes a translation useful and how to set up translated pages correctly.
Read article →Google added product categories, sale dates, an adult content label and a stricter fake-review rule to its product markup documentation in 2026. Here's what to mark up, how to keep the page, the markup and the Merchant Center feed in step, and how to test it.
Read article →Google doesn't demote pages for being AI-generated, but its 2026 documentation sets a clear bar for low-value content at scale. Here's what Google says, what practitioners have seen, how to use AI without producing slop and how to audit your site for it.
Read article →A page that slowly loses clicks isn't always decaying, and a new date rarely fixes it. Here's how to confirm the decline, rule out other causes, and decide whether to update, rewrite, merge or leave the page alone.
Read article →Google now says it plainly: one crawl capacity limit per hostname, shared by Googlebot, Shopping, ads and image crawlers. Learn what that means, where crawling leaks away, and how to measure it in your own logs.
Read article →A page with only one internal link pointing to it isn't automatically a problem. Learn how to spot the pages that need a better path, where to add links that help readers, and when to leave things alone.
Read article →/page and /page/ can be two different URLs. Learn when a trailing slash mismatch matters, when a redirect is healthy, and how to audit and fix the signals around your preferred URL.
Read article →Click depth shows how many internal links separate a page from your starting point. Learn when a deep page needs attention, why pagination is different, and how DeepSpider.ai evaluates it.
Read article →An issue count becomes useful when the evidence, affected pages and next step remain visible together.
