01 — CRAWLABILITY

Crawlability & Indexing — Let Google In

The first step of technical SEO is ensuring that Google's crawler (Googlebot) can properly crawl and index your website. If the crawler is blocked, your site simply won't appear in search results — no matter how great your content is.

robots.txt is a text file at your root domain (e.g. mrshah.website/robots.txt) that tells Googlebot which pages to crawl and which to skip. Blogger generates this automatically — but you should always check it.

# Allow all crawlers
User-agent: *
Disallow: /search
Allow: /

# Sitemap location
Sitemap: https://www.mrshah.website/sitemap.xml

An XML Sitemap gives Google a complete list of all pages on your site. Blogger auto-generates one at /sitemap.xml. Submit it in Google Search Console to speed up indexing.

02 — PAGE SPEED

Page Speed — Every Second Costs You

Google has officially confirmed that page speed is a ranking factor. A slow website means higher bounce rates, less time on page, and ultimately weaker rankings. On mobile especially, every second matters.

The most common speed problems on Blogger blogs are: oversized images, too much JavaScript, and unoptimized fonts. Fix these three and you can dramatically improve your score.

03 — MOBILE-FIRST

Mobile-First Indexing — Mobile Is Now Primary

Since 2024, Google has fully adopted Mobile-First Indexing. This means Google looks at your website's mobile version first — not desktop. If your mobile experience is poor, your rankings will suffer regardless of your desktop design.

Your Blogger theme must be responsive — meaning it looks correct on every screen size. Text should be readable without zooming, buttons large enough to tap, and content should never scroll horizontally.

04 — SITE STRUCTURE

Site Structure & Clean URLs — Don't Confuse Google

Your website's structure should be logical and clear. When Google crawls your site, it needs to understand which pages are important and how they relate to each other. A well-organized site gets crawled more efficiently.

Clean URLs are a simple but powerful factor. A URL like /technical-seo-basics tells both Google and users exactly what the page is about. Avoid random numbers and symbols in your URLs.

05 — SCHEMA MARKUP

Schema Markup — Earn Rich Snippets

Schema markup is structured data that tells Google exactly what your content is — an article, recipe, FAQ, product, or review. The benefit: Google can display your result as a rich snippet with star ratings, dates, and extra information visible directly in search results.

For a blog, Article schema is the most important. Adding it makes your result more eye-catching in search — which directly increases your click-through rate.

06 — HTTPS

HTTPS & Security — A Trust Signal Google Loves

Google treats HTTPS as a confirmed ranking signal. If your website still runs on http://, that is an urgent fix. Enabling HTTPS on Blogger with a custom domain is completely free and takes under a minute.

Go to: Blogger Dashboard → Settings → HTTPS → Enable HTTPS Redirect. That's it. Your domain is now secure and Google will treat it accordingly.

07 — CORE WEB VITALS

Core Web Vitals — Google's Report Card for Your Site

Core Web Vitals are three metrics Google uses to measure real user experience — and they directly affect your rankings. Understanding and improving them is non-negotiable in modern SEO.

CLS is very common on Blogger — it happens when fonts or images load and push other content around. Always set a fixed width and height attribute on every image so the browser reserves space before the image loads.
