💬 Technical SEO — Build a Solid Foundation

🌐 Website Speed & Core Web Vitals

An asset produces value over time. Properties that qualify as assets are owned, scalable, measurable and appreciate with investment. Your website can be that asset when it is:

• ✅ Run PageSpeed Insights. Aim for LCP < 2.5s, low CLS and fast INP/FID.
• ✅ Serve optimized images (WebP/AVIF), use responsive images (`srcset`) and lazy-loading for below-the-fold pictures.
• ✅ Enable caching, HTTP/2 or HTTP/3, and use a CDN for global delivery.

🌐 Mobile-Friendly & Responsive

• ✅ Ensure mobile responsiveness; run the Mobile-Friendly Test.
• ✅ Adopt a mobile-first CSS strategy and avoid fixed-width elements.

🌐 Indexing & Crawlability

• ✅ Check `robots.txt` and XML sitemap. Submit sitemap to Google Search Console.
• ✅ Use canonical tags for duplicate/alternate pages.

🌐 Security & HTTPS

• ✅ Serve only over HTTPS. Renew certificates and enforce HSTS.
• ✅ Monitor Google Safe Browsing and fix any flagged issues.

💬 On-Page SEO — Optimize Every Page

🌐 Title Tags & Meta Descriptions

• ✅ Unique title per page with primary keyword near the front (≤ 60 chars).
• ✅ Compelling meta description (120–160 chars) to improve CTR.

🌐 Heading Structure

• ✅ Use H1 for page title, H2 for main sections, H3 for subsections. Keep hierarchy logical.

🌐 Content & Keyword Usage

• ✅ Match content to user intent, use long-tail keywords naturally, and target one main topic per page.
• ✅ Place target keyword within first 150 words and in at least one H2 or H3.

🌐 Images & Alt Text

• ✅ Descriptive `alt` attributes that explain the image and, when relevant, include keywords naturally.
• ✅ Use SEO-friendly filenames like `progressive-web-app-pwa-shainjal.webp`.

💬 Content Strategy — Help & Authority

🌐 Create Valuable, Link-Worthy Content

• ✅ Publish long-form how-to guides, industry studies, and case studies that attract backlinks.
• ✅ Use content clusters: one pillar page with related topic pages linked internally.

🌐 Update & Refresh

• ✅ Refresh older posts with updated statistics, dates, and better examples.

🌐 Multimedia & Engagement

• ✅ Embed videos (YouTube), infographics, and interactive widgets to increase dwell time.

💬 Content Off-Page SEO — Build Authority

🌐 Backlinks

• ✅ Prioritize high-quality, relevant backlinks over quantity. Guest posts, PR, and research citations work best.
• ✅ Avoid link schemes and low-quality directories.

🌐 Brand Mentions & Social Signals

• ✅ Encourage brand mentions and shares. Maintain consistent NAP (Name/Address/Phone) across directories.

💬 Local & International SEO

🌐 Google Business Profile (GBP / GMB)

• ✅ Claim and fully optimize GBP: categories, images, posts, and accurate contact details.
• ✅ Encourage and respond to reviews — review signals impact local visibility.

🌐 Multilingual & Hreflang

• ✅ For multi-country targeting, implement `hreflang` tags and localized content with appropriate currency & formats.

• ✅ Organization (homepage), WebSite (search action), Article (blogs)
• ✅ FAQPage, Product, Service, BreadcrumbList for specific pages

Use the Rich Results Test to validate your markup.

Implement JSON-LD for these types where applicable:

• ✅ Google Search Console: Indexing, coverage, and performance reports.
• ✅ Google Analytics 4: Audience behavior and conversion tracking.
• ✅ Site audit tools: Ahrefs, SEMrush, Screaming Frog for technical finds.

🌐 Monthly Process

• ✅ Run a technical audit, review keyword movements, check backlinks, and implement prioritized fixes.

💬 SEO Myths to Avoid

• ❌ Keyword stuffing helps → False.
• ❌ Buy backlinks for instant results → Dangerous & short-term.
• ❌ SEO is one-time → Ongoing.
• ✅ Quality + Consistency = Real SEO success.

Q1: How often should I run an SEO audit?

Monthly or at least once every 60 days depending on your website complexity and change frequency.

Q2: Will schema markup get me into rich results automatically?

Schema makes your content eligible for rich results, but Google decides whether to display them. Use correct markup and high-quality content to increase chances.

Q3: Does SEO still beat paid ads?

SEO builds sustainable organic channels and trust; paid ads are complementary for short-term visibility and campaigns.
