★★★ Why does a link without an indexed URL essentially do nothing for your SEO?

★★★ Do brand mentions without backlinks actually help your SEO rankings?

★★★ Does Google really use just one signal to choose which URL to canonicalize among your duplicate content?
Regarding canonicalization, several factors play a role: the rel canonical tag, internal and external links, what is listed in the sitemap, redirects, and sometimes which URL appears cleaner or cleare...

★★★ Does Google really ignore your canonical tags when it decides pages are too similar?

★★ Does partial duplicate content really hurt your search rankings?

★★ Are out-of-stock products hurting your e-commerce site's overall search rankings?
When something is out of stock, we'll treat it more like a soft 404 error and remove that URL from search results. However, if only a single product reference is out of stock, the ranking of the rest ...

★★★ Why does robots.txt prevent Google from crawling your pages but still allow them to be indexed?
With robots.txt, you prevent crawling of these URLs but not their indexation. If you run a site: search for these specific URLs, you'll very likely still find them in the index, even without the conte...

★★ Should you really avoid URLs with parameters for SEO?
There's a general assumption that URLs with parameters are bad for a site, and that's simply not the case. It's not something I would consider critical; it's more about polishing the site to make it a...

★★ Does the order of links in your HTML code really affect Google's crawl priority?
If we look at an HTML page, the order of the links is not related to the order of our overall crawl of these pages on the site. As long as these links are on the HTML page and we can follow them, we c...

★★★ Does Google really count clicks on rich results the same way as organic clicks?
For rich results, we count a click only if there's actually a link to your site and someone clicked on it. It's not the case that we'd say there's a rich result and therefore count a click even if no ...

★★★ Why does Google deprioritize crawling low-effort aggregator sites?
Google's algorithms are not invested in crawling and indexing all content from low-effort aggregator sites that merely take content feeds and publish them, because it's the same content already seen e...
Mar 28, 2022 ⚡ Analysis available
★★★ Does Google really use different ranking algorithms depending on your industry?
Google has nothing specific regarding different algorithms for different niches. A bike shop doesn't have completely different algorithms from a shoe shop. They're essentially both e-commerce stores....

★★★ Do Google's testing tools really crawl in real-time or do they rely on cached data?
The mobile-friendly test and URL inspection tool do not use any cached data to display information. They really retrieve this information live directly from your server....

★★ Can out-of-stock product pages really trigger soft 404 errors in Google's eyes?
Soft 404s can be products that are out of stock or no longer available. This can also be an empty page or an error in the DOM if something with JavaScript loads an error message like 'no information f...

★★★ Should you really prefer noindex over disallow to control indexation in Google?
If these are pages you don't want indexed, using noindex would be better than disallow in robots.txt. Noindex is a meta robots tag on the page, and you must allow crawling for it to work....

★★ Is Google Search Console really collecting all the data from your massive e-commerce site?
