Technical SEO in Delhi

Coaching institutes: notes, batches and result-day surges

Delhi's coaching institutes, especially those preparing students for civil services, commerce and other competitive examinations, run websites that behave differently from ordinary business sites. Traffic surges when results, answer keys or admission announcements come out, and a site that slows or fails at those moments loses both visitors and crawl attention. Study material is often published as large PDFs, current affairs notes accumulate daily, and course and batch pages are copied each session with small changes.

The technical questions worth examining on such sites are:

• Whether caching and hosting can handle predictable peaks, and whether key pages stay fast when they do
• Whether valuable notes exist only as PDFs, and whether an HTML version or summary page would serve searchers better
• How old batch and course pages are retired: redirected to the current version, kept as archives or removed
• Whether daily content creates thin, near-identical pages that dilute the site
• Whether material locked inside an app or behind login is expected to rank, which it generally cannot

Many of these sites mix Hindi and English material, and the script and URL considerations for that are on my technical SEO India page. My Delhi work focuses on structure, lifecycle and load.

Wholesale catalogs with price on request

Delhi wholesalers and trading houses increasingly put their catalogs online, often on low-cost ecommerce or catalog platforms set up by a local developer. Prices are usually hidden behind an inquiry button, since rates depend on quantity and customer. The catalog may hold many near-identical items that differ only in size, color or pack, and filters for brand, category and specification generate a new URL for every combination.

Left alone, this produces a site where search engines spend their time on filter combinations and duplicates while important category pages are crawled rarely. Item pages with nothing but a name, an image and an inquiry button also give search engines little reason to rank them.

I define a crawl policy for the catalog: which filter pages deserve to be indexable because buyers actually search for them, which should be canonicalized or kept out of the index, and how internal links point to the pages that matter. For item pages, I specify the minimum useful content, such as specifications, pack sizes and applications. Discontinued items are redirected to the closest alternative or category rather than left as errors. For the full diagnostic approach, see technical SEO audit.

City selectors and pin code checks across the NCR

Businesses delivering or providing services across the NCR, such as grocery and food delivery, home services, furniture and appliance retailers, diagnostics and pharmacies, often ask visitors to choose a city or enter a pin code before showing products, prices or availability. Some redirect visitors automatically based on their IP address. These choices make sense for customers, but they can hide much of the site from search engines.

Crawlers generally do not fill in pin codes or click city selectors, and they may crawl from locations that the site misidentifies. If a pop-up blocks the content, or a redirect sends every visitor to one city's version, other cities' pages may never be indexed properly. I test the site as a crawler would and check what is rendered without any location chosen.

Typical fixes include keeping a crawlable default version of each page, giving each city or locality page its own stable URL rather than relying on cookies, showing a location prompt that does not block the main content, and avoiding forced IP redirects. Location pages for Delhi, Gurugram, Noida and other cities should each carry genuinely local information, so they are not treated as duplicates of one another.

Exporters whose collections live in images

Garment, home furnishing and handicraft exporters across the NCR often present their work to overseas buyers as lookbooks: large images, image-only PDFs or galleries with little text. Some keep their collections behind a buyer login. The result looks attractive but tells search engines almost nothing, so the site rarely appears when a buyer abroad searches for a product type, material or technique.

The goal is not to publish confidential buyer collections. It is to make the public side of the business readable. I recommend category pages for product types, materials and techniques with descriptive text, capabilities pages explaining processes and compliance standards the exporter works to, and image galleries where each image has a meaningful file name and alt text.

Performance matters too, because visitors are abroad and images are heavy. I check image formats, sizing and lazy loading, and whether a content delivery network serves files quickly in the buyer's region. Where an exporter targets several countries, the language and country targeting questions are covered on my international SEO strategy page.

Suppliers whose certificates and specifications are scanned

Many Delhi businesses that sell to government departments, public sector buyers and large institutions have websites that mainly hold scanned documents: quality certificates, product approvals, test reports, empanelment letters and specification sheets. A procurement officer or engineer searching for a product with a particular specification will rarely find these, because a scanned image of a page contains no searchable text.

I identify which documents carry information buyers search for and plan how to expose it. Usually that means a product page for each item or range, stating the specification, applicable standards and approvals in text, with the scanned certificate attached as supporting evidence rather than as the only content. Where PDFs stay, they should contain real text, have descriptive titles and be linked from relevant pages.

I also check common problems on these sites: upload folders blocked from crawling, broken links to expired certificates and outdated documents still ranking for a product name. Accuracy matters, so each certificate page needs an owner who replaces it when it is renewed.
