What are Webmaster Tools?
The term Webmaster Tools is the historical name for what is now called Google Search Console (renamed in 2015). It refers to tools provided by search engines to help site owners monitor and optimize their presence in results. Google Search Console is the reference tool: it provides direct access to the data Google collects about your site, the same data it uses to decide how it ranks and displays your pages.
What Google Search Console enables in 2026
GSC has considerably expanded its features in recent years. Key reports in 2026:
- Performance: impressions, clicks, CTR, and average position by query and page. Since 2024, GSC integrates a breakdown of AI Overview performance.
- Index Coverage: indexed, excluded pages, and reasons for exclusion.
- URL Inspection: see exactly how Googlebot rendered a page, check indexing status, request a recrawl.
- Core Web Vitals: LCP, INP, CLS by device type with affected URLs.
- Links: external backlinks, internal links, and anchor text.
- Enhancements: structured data errors, breadcrumbs, FAQ, and other rich results.
What we observe at Vydera on GSC usage
GSC is systematically the first data source in our audits. It's also often where we find the first problem indicators: pages with dropping traffic but stable impressions (CTR problem signal), URLs excluded for "duplicate content" that the client wasn't aware of, Core Web Vitals errors never detected. GSC is free, official, and irreplaceable. There's no excuse for not using it.
How to use Google Search Console effectively
- Check the Performance report weekly to detect abnormal variations.
- Monitor the Coverage report after every deployment or significant update.
- Use URL Inspection after publishing new strategic pages.
- Enable email alerts to be notified of critical issues.

Google Search Console vs Google Analytics: what's the difference?
Google Search Console measures your site's visibility in Google results: impressions, clicks, positions, indexing, Core Web Vitals. Data is seen from Google's side. Google Analytics measures visitor behavior on your site after the click: sessions, page views, conversion rate, user journey. Both are complementary and cover different scopes. GSC explains why visitors arrive, GA explains what they do next.
How often should you check Google Search Console?
At minimum once a week to detect traffic variations or technical errors. After every site deployment or significant change, check the Coverage report and URL Inspection for affected pages. When a Google algorithmic update (Core Update) happens, analyze before/after Performance data to identify positively or negatively impacted pages.
Does GSC show AI Overview data?
Partially. Google Search Console integrated AI Overview-specific data into the Performance report in 2024: you can see impressions and clicks generated via AI Overviews for your pages. It's not complete (no detail on the AI Overview content citing you), but it's a valuable signal for measuring your generative visibility within Google.
Is Bing Webmaster Tools useful?
Yes, especially in 2026. Bing powers Microsoft Copilot, one of the most used LLMs in enterprise. Bing Webmaster Tools lets you submit your sitemap, verify Bing indexing, and get performance data on Bing Search and Bing Chat. Sites ignoring Bing miss a non-negligible share of AI visibility, especially in the B2B market.
