1. Crawling: can search engines reach your pages?
Crawling is the first step. Googlebot, Bingbot and AI crawlers such as GPTBot and PerplexityBot follow links and sitemaps to discover URLs. If a page is blocked in robots.txt, buried six clicks deep, or only reachable through JavaScript that bots cannot execute, it may never be discovered. Large sites also face crawl budget limits, where Google spends its time on low-value URLs like filters, session IDs and tag pages instead of the pages that make money.
Top SEO Agency reviews your robots.txt, XML sitemaps, internal link depth and server log files to see exactly which URLs bots request, how often and with what response codes. We then remove crawl traps, consolidate parameter URLs and make sure every important page is no more than three clicks from the homepage.
2. Rendering: can bots see your content?
Modern websites built with React, Next.js, Vue or Angular often rely on JavaScript to load content. Google can render JavaScript, but it does so in a second wave that can take days, and many AI crawlers do not render JavaScript at all. If your main content, links or product data only appear after scripts run, search engines may index an empty shell.
We compare the raw HTML with the rendered DOM, test pages with the URL Inspection tool and recommend server-side rendering, static generation or dynamic rendering where needed, so both Google and AI crawlers see the full page on the first request.
3. Indexing: are the right pages in Google?
Being crawled is not the same as being indexed. Google Search Console often shows pages as "Crawled, currently not indexed" or "Discovered, currently not indexed". Common causes include thin or duplicate content, conflicting canonical tags, accidental noindex tags left over from staging, soft 404s and weak internal linking that signals a page is unimportant.
Our technical SEO audit maps every URL to its index status, identifies the cause for each excluded group and fixes it at the template level. We also make sure pages that should not be indexed, such as internal search results and thin filter combinations, are kept out so they do not dilute quality signals.
4. Site speed and Core Web Vitals
Core Web Vitals measure real user experience: Largest Contentful Paint (LCP) for loading, Interaction to Next Paint (INP) for responsiveness and Cumulative Layout Shift (CLS) for visual stability. They are a confirmed Google ranking signal and have a direct effect on conversion rates.
Top SEO Agency fixes speed issues at the template level, so a single change improves thousands of pages at once, then tracks field data in the Chrome User Experience Report to confirm the gains.
5. Site architecture and internal linking
Site architecture decides how authority flows through your website. A flat, logical structure with clear categories, breadcrumbs and contextual internal links helps Google understand which pages matter most and helps users find what they need. Poor architecture leaves orphan pages with no internal links, spreads authority too thin and creates keyword cannibalization where several pages compete for the same search.
We map your site into topic clusters, assign one primary keyword to each URL and build an internal linking plan that pushes authority to your highest-value service, category and product pages.
6. Structured data and schema markup
Schema markup is code that describes your content in a language search engines understand: organization details, products, prices, reviews, FAQs, articles, local business information and more. It powers rich results such as star ratings and FAQ dropdowns, and it helps AI systems like Google AI Overviews and ChatGPT extract accurate facts about your brand.
Top SEO Agency implements and validates JSON-LD schema for Organization, WebSite, LocalBusiness, Product, Review, FAQPage, Article, BreadcrumbList and Service types, and connects your entities with sameAs links to your social and review profiles.
7. International and multi-language SEO
Brands selling in several countries need hreflang tags to tell Google which version of a page to show in each market. Missing or broken hreflang causes the wrong country page to rank, splits authority and confuses users. We audit hreflang return tags, x-default settings, currency and language signals, and choose the right structure between subfolders, subdomains and country domains.
8. Site migrations without traffic loss
Redesigns, platform changes, domain moves and HTTPS migrations are the most common cause of sudden organic traffic drops. Top SEO Agency builds a full redirect map from every old URL to its closest new match, audits the staging site before launch, runs post-launch crawls and monitors rankings daily for the first 30 days. For ECORN Agency, this process delivered a full Webflow migration with zero loss in indexing and rankings.
9. Technical SEO vs on-page SEO vs off-page SEO
SEO is usually split into three parts. Technical SEO makes sure search engines can access and understand your site. On-page SEO makes each page relevant to the searches it targets, through titles, headings, copy, images and internal links. Off-page SEO builds trust from outside your site through backlinks, reviews, brand mentions and digital PR. Technical SEO is the foundation the other two sit on. Great content on a page Google cannot index earns nothing, and backlinks pointing to a slow, broken page lose most of their value.
Top SEO Agency runs all three as one plan. The technical audit tells us which pages are ready to rank, the content plan decides what to publish or improve, and link building pushes authority to the pages that matter most.
10. Technical SEO for large, eCommerce and JavaScript sites
Large websites face problems small sites never see. eCommerce stores with thousands of products create millions of filter and sort combinations that waste crawl budget and generate duplicate content. Marketplaces and publishers add hundreds of new URLs every day and need fast discovery through clean sitemaps and internal linking. SaaS sites built as single-page applications often hide their core content behind JavaScript that AI crawlers never execute.
For these sites, Top SEO Agency uses log file analysis to see exactly how bots spend their time, sets rules for which parameter URLs can be crawled and indexed, and works with your engineers on rendering strategies such as server-side rendering or static generation. The goal is simple: every valuable page crawled quickly, every low-value URL kept out of the way.
