Technical SEO Audit: A Repeatable Framework for Performance Technical SEO is not about guessing; it is about removing friction between search engine crawlers and your content. This guide provides a repeatable workflow to identify and prioritize fixes that move the needle. 1. Crawl and Index Coverage Your first goal is to understand how Google views your site architecture. The Tool: Screaming Frog SEO Spider. The Workflow: Run a crawl of your domain. Export the "All" report. Checklist: Status Codes: Filter by 4xx (broken links) and 5xx (server errors). Redirect Chains: Identify 301 chains (more than one hop). Index Coverage (GSC): Go to Google Search Console > Indexing > Pages. Look for "Crawled - currently not indexed" and "Discovered - currently not indexed." Common Mistake: Ignoring "Crawled - currently not indexed." This usually means low-quality content or lack of internal link authority. 2. Core Web Vitals (CWV) G...

Building a lead-capturing Telegram bot is a high-ROI task. You need stability, data integrity, and a clean deployment pipeline. We will use aiogram (v3+) for the bot logic and gspread for Google Sheets integration. Architecture and Prerequisites Framework: aiogram (asynchronous, robust). Database/Storage: Google Sheets (via Google Sheets API) for simplicity, or PostgreSQL for scale. Deployment: Ubuntu 22.04+ VPS + systemd for process management. Anti-Spam: Rate limiting via aiogram middleware. Checklist [ ] Telegram Bot Token (from @BotFather). [ ] Google Cloud Project with "Google Sheets API" enabled. [ ] Service Account JSON key file. [ ] VPS with Python 3.10+ installed. The Code Skeleton Install dependencies: pip install aiogram gspread oauth2client . bot.py import asyncio from aiogram import Bot, Dispatcher, types, F from aiogram.filters import Command from aiogram.fsm.context import FSMContext from aiogram.fsm.state import State, StatesGroup ...

Core Web Vitals Optimization: A Hands-On Guide Core Web Vitals (CWV) are no longer optional. Google uses them as a ranking factor, and poor scores directly correlate with higher bounce rates. This guide is for developers and site owners who want to move the needle from "Needs Improvement" to "Good" without fluff. Step 1: Measurement and Diagnostics Before changing a single line of code, establish a baseline. PageSpeed Insights (PSI): Run your URL. Look at the "Field Data" (real-user experience) first. If that’s empty, look at "Lab Data." Chrome DevTools: Open the Lighthouse tab for a quick audit, but use the Performance tab to record a trace. This shows you exactly which script or image is blocking the main thread. Web Vitals Extension: Install the "Web Vitals" Chrome extension to see real-time CLS and INP as you navigate your site. Common Mistake: Relying solely on lab data. Lab data is simulated on a throttled connectio...

Building a lead-capturing Telegram bot requires a robust architecture to ensure data integrity and uptime. We will use aiogram (the industry standard for asynchronous Telegram bots in Python) and Google Sheets API as a lightweight CRM. Prerequisites and Setup You need a VPS running Ubuntu 22.04+, Python 3.10+, and a Telegram Bot Token from @BotFather . 1. Google Sheets API Setup Go to Google Cloud Console . Create a project and enable Google Sheets API and Google Drive API . Create a Service Account, download the JSON key file, and rename it to credentials.json . Share your target Google Sheet with the client_email found inside credentials.json . Code Skeleton Install dependencies: pip install aiogram gspread oauth2client Main Bot Logic (bot.py) import asyncio import logging from aiogram import Bot, Dispatcher, types, F from aiogram.filters import Command from aiogram.fsm.context import FSMContext from aiogram.fsm.state import State, StatesGroup import gspread from oau...
