SEO Web Architecture in Burgos — The structure Google needs to rank you

Information architecture is the discipline that studies how to organise, label and structure the content of a website so it is easy to navigate for users and crawl for search engines. In SEO, good information architecture translates into pages that Google can discover, classify and rank effectively because the site structure clearly communicates which are the main topics, which are secondary and how they relate to each other.

Googlebot, Google's crawl robot, discovers website pages by following internal links from the homepage. If a page has no links pointing to it from other pages on the site, the robot may never find it. Once it finds it, the depth at which it is in the website hierarchy (how many clicks from the homepage) influences the frequency with which it crawls it and the relative authority it assigns to it. Pages more than 4 clicks deep rarely rank well.

Crawl budget is the number of pages Googlebot is willing to crawl on your site in a period of time. For large sites, a poorly managed crawl budget means important pages are not crawled frequently enough to reflect their updates in the index. A well-designed architecture concentrates the crawl budget on the highest-value SEO pages, preventing the robot from wasting time on pages of little interest such as e-commerce filters, empty tag pages or duplicate parametrised URLs.

An orphan page is a page with no internal links pointing to it. Google can only discover it if it is in the XML sitemap, but without internal linking it receives no authority from any other page and rarely ranks well. In Burgos it is common to find important service pages on construction, health or professional services companies that have been published for years and have never ranked because no one links to them from the rest of the website.

Cannibalisation occurs when several pages on the same website compete for the same keyword. Google does not know which to show and ends up rotating between them, meaning none ranks stably in the Top 3. A well-designed architecture assigns a unique primary keyword to each page and groups related pages into topic silos where each covers a different angle of the same topic.

The SEO authority of a domain is distributed between its pages through internal links. A website with many backlinks pointing to the homepage but with poor internal linking has all its authority concentrated on the homepage, which does not reach the rest of the pages. For service landing pages and category pages to rank well, they need to receive authority through a well-designed internal linking network.

The first step for any web architecture project is understanding the current state: we crawl the full website with Screaming Frog to map all URLs, identify orphan pages, detect cannibalisations, analyse crawl budget distribution and evaluate internal linking logic. This diagnosis reveals the specific problems limiting the website's SEO performance and defines restructuring priorities.

Topic silos are the most efficient way to organise website content for SEO. Each silo groups related pages on the same topic, creating a clear thematic signal for Google and concentrating authority within each area. For a business in Burgos with several services, each main service can be an independent silo with its own page hierarchy.

The URL structure should reflect the content hierarchy and contain the relevant keywords at each level. A URL like domain.com/services/local-seo-burgos is clearer for both Google and the user than domain.com/p=1247. We define the URLs for all pages on the site following SEO conventions: short URLs, no special characters, with main keywords and in lowercase with hyphens as separators.

Internal linking is the infrastructure that distributes authority between pages and that Google uses to understand the site's thematic relationships. We design an internal linking plan that defines which pages link to which, with what anchor text and with what priority criterion, ensuring authority flows efficiently to the pages we want to rank.

Topic silos group pages from the same area under the same branch of the architecture, creating very clear thematic consistency signals for Google. For a renovation company in Burgos, one silo could be "kitchen renovations" with pages on kitchen types, materials, budgets and real cases; another silo would be "bathroom renovations" with its own hierarchy. This organisation tells Google that the website is a specific reference in each of those sub-topics.

Internal links are the pipes through which SEO authority flows within a website. Each link transfers part of the authority from the source page to the destination page (internal PageRank). A page with many internal links pointing to it receives more authority than one that only has a link from the homepage. Consciously designing this link network is what distinguishes a website that ranks efficiently from one that wastes its potential.

URLs are relevance signals for both users and Google. A descriptive URL like /services/web-design-burgos immediately communicates what the page is about and contains the target keyword. Long URLs with parameters, ID numbers or meaningless words like /page?id=4782&cat=3 provide no semantic signal and are difficult to remember and link to. The URL is one of the first relevance factors Google evaluates.

Breadcrumbs are the navigation path showing the user where they are within the site hierarchy: Home > Services > Local SEO > Local SEO Burgos. For Google, breadcrumbs are clear signals of the site's hierarchical structure and, when implemented with BreadcrumbList Schema, appear in search results instead of the full URL, improving CTR. They are mandatory on any website with more than two depth levels.

Category pages and pagination pages require special treatment in SEO architecture. Category pages should have their own SEO content (a descriptive text with relevant keywords) in addition to the listing of pages or products. Pagination should be managed with rel="next" and rel="prev" for Google to understand the relationship between pages in the same series. Pagination pages without unique content and without proper management can waste crawl budget and generate duplicate content.

We crawl the full website and analyse the existing structure: hierarchy depth, crawl budget distribution, detection of orphan pages and cannibalisations, internal linking analysis and URL structure evaluation. This audit is the diagnosis that identifies what to keep, what to improve and what to remove.

With keyword research and diagnosis as a basis, we design the new web architecture as a tree: the complete hierarchy of pages from the homepage to the last level, grouped in coherent topic silos. We deliver this design in visual format (content tree) and in a written document with the SEO justification for each structural decision.

With the approved structure, we define the exact URL for each page following SEO conventions. We identify which pages need new keyword research or new content and which can be optimised with existing content. We also define the canonical tags needed to manage potential duplicates and the robots meta tags for pages that should not be indexed.

The final deliverable is the internal linking plan: which pages link to which, with what anchor texts and in what sections. If the restructuring involves changing existing URLs, we also define the 301 redirect map needed to preserve accumulated SEO authority. With this plan, the development team can implement the new architecture without risk of losing ranking.
