What is the most common technical SEO problem?

The most common technical SEO issues across Delhi websites are: slow page speed and poor Core Web Vitals scores (usually from unoptimised images and excessive plugins); missing or incorrect meta robots tags causing unintentional noindex; duplicate content from URL parameters or multiple page versions; missing schema markup; and poor mobile experience.

How do I check my website's Core Web Vitals?

Google provides free tools to check Core Web Vitals: Google Search Console's Core Web Vitals report shows field data from real users; Google PageSpeed Insights provides both lab and field data with specific recommendations; and the Chrome User Experience Report provides aggregate performance data. For a comprehensive technical audit, contact SEOSpidy for a free website review.

Does page speed directly affect Google rankings?

Yes — Google confirmed page speed as a ranking factor in 2010 for desktop and 2018 for mobile, with Core Web Vitals becoming explicit ranking signals in 2021. While page speed is not the most powerful ranking factor, failing Core Web Vitals thresholds can suppress rankings — particularly in competitive markets where technical quality is a differentiator.

What is an XML sitemap and do I need one?

An XML sitemap is a file that lists all the pages on your website you want Google to index, along with metadata about each page. It helps Googlebot discover and crawl your pages efficiently, particularly important for large websites or new pages that may not yet have many inbound links. Every website benefits from a properly maintained XML sitemap submitted to Google Search Console.

What is structured data and do I need it for SEO?

Structured data (schema markup) is code that tells Google explicitly what your content means — enabling rich results like star ratings, FAQ dropdowns and product information in search results. While structured data is not a direct ranking factor, rich results improve click-through rates significantly. For local businesses in Delhi, LocalBusiness schema is particularly important.

Key Takeaway

Technical SEO is the optimisation of your website's infrastructure — speed, crawlability, indexation, mobile-friendliness and structured data — ensuring Google can efficiently access, understand and rank your pages.

Core Web Vitals — Google's Performance Ranking Signals

Core Web Vitals are Google's standardised metrics for measuring user experience quality — confirmed as ranking signals since 2021. There are three metrics:

LCP (Largest Contentful Paint) — measures loading performance. Target: under 2.5 seconds. Slow LCP is usually caused by unoptimised images, slow server response or render-blocking resources.

FID (First Input Delay) / INP (Interaction to Next Paint) — measures interactivity. Target: under 200ms. Poor scores typically result from heavy JavaScript execution.

CLS (Cumulative Layout Shift) — measures visual stability. Target: under 0.1. Common causes are images without dimensions and dynamically injected content.

Our technical SEO service addresses all Core Web Vitals issues systematically.

Crawlability and Indexation

Crawlability refers to how easily Googlebot can navigate and download your website's pages. Common issues: incorrect robots.txt rules blocking important pages; JavaScript-rendered content that Googlebot struggles to process; internal linking gaps leaving pages undiscoverable; and pagination problems.

Indexation refers to which pages are included in Google's index and can appear in search results. Common issues: duplicate content creating indexation confusion; noindex tags accidentally left on live pages; thin or low-quality pages diluting overall site quality; and canonicalisation errors.

Structured Data and Schema Markup

Schema markup (structured data) is code added to your website that helps Google understand your content's context. It can generate "rich results" in Google — enhanced search listings showing star ratings, FAQ dropdowns, event dates, product prices and more.

Common schema types for Delhi businesses: LocalBusiness (essential for local SEO), FAQPage (generates FAQ accordions in search results), Service, Product, Article and BreadcrumbList. Implementing schema correctly can significantly improve click-through rates from search results.

Mobile-First Indexing

Google switched to mobile-first indexing in 2021, meaning Google primarily uses your mobile website — not your desktop version — when crawling, indexing and ranking your pages. If your mobile site has less content, slower speed or poorer user experience than your desktop site, your rankings will suffer.

Key mobile technical requirements: responsive design that adapts to all screen sizes; font sizes legible without zooming; tap targets spaced sufficiently for touch navigation; no horizontal scrolling; and equivalent content on mobile and desktop versions.
