Prafero: The All-in-One Website Audit Platform for SEO, Performance, Security, DNS, and Technology Insights
A successful website is not only about attractive design or good content. Behind every high-performing website, there are many technical factors that affect search rankings, user experience, security, loading speed, accessibility, and trust. If one part of your website is weak, it can reduce visibility, slow down performance, create security risks, or make users leave before they take action.

Does Page Speed Affect SEO? Yes — Here's Exactly How (2026)
Page speed affects SEO directly and indirectly. Google uses three Core Web Vitals metrics — LCP, INP, and CLS — as confirmed ranking signals measured from real user data. Slow pages also generate higher bounce rates and shorter dwell time, which send negative behavioural signals that compound the direct ranking penalty. In 2026, slow sites additionally lose visibility in AI search engines including Google AI Overviews, ChatGPT, and Perplexity. The short answer is yes. The full answer is that speed now affects your rankings through four separate channels simultaneously — and most sites are only optimising for one of them. Want to know where you stand right now? Run your URL through Prafero's free page speed checker — no signup, instant Core Web Vitals results.

Paste any domain into the Robots Txt Checker and see exactly which rules are live, what they block, and whether your most important pages are reachable — instantly, with no signup. This guide covers everything: what robots.txt actually does, how to read every directive, how to fix the two Search Console errors everyone runs into, how to control AI crawlers like GPTBot and ClaudeBot, and the mistakes that quietly tank traffic.

How to Check Meta Tags of Any Website (Free, No Signup)
Meta tags live in the <head> section of every webpage — invisible when you load the page normally, but read by every search engine and social platform that touches that URL. If you want to see what a page's title tag, meta description, canonical, or Open Graph tags actually say, you have three options: dig through the browser's developer tools, view the raw page source, or use a tool that extracts everything in one pass. This guide walks through all three methods, what to look for once you can see the tags, and when each approach makes sense. If you just want the fastest route, skip to Method 3 and use Prafero's free Meta Tag Analyzer — paste any URL and every meta tag appears instantly with no signup required.
