Technical on-page foundations
Crawlable HTML, canonical URLs, robots directives, XML sitemaps, HTTPS, trailing-slash consistency and indexable templates instead of JS-only shells.
On-Page SEO
On-page SEO optimization that search engines and people can actually use
On-page SEO is the work that happens on the website: titles, descriptions, headings, URLs, internal links, structured data, image alternatives, crawlable HTML and page performance. ZEH Technologies implements this as engineering and content structure—not as a ranking package and not as a monthly keyword report that never touches the site.
We do not promise positions. Rankings depend on demand, competition, backlinks and the quality of the content you publish. We do make pages that search engines can crawl, understand and index, and that visitors can read without fighting the template.
What on-page SEO covers
Metadata and headings
Unique titles and meta descriptions per URL, one clear H1, heading hierarchy that matches the topic, and Open Graph tags that match the page.
Internal linking and IA
Breadcrumbs, hub pages, related services and in-copy links so important URLs are not orphans.
Structured data
JSON-LD for Organization, WebSite, WebPage, Service, FAQ, BreadcrumbList and Article where the page type supports it.
Multilingual SEO
hreflang, locale-prefixed URLs, x-default, translated metadata and sitemap alternates for every language the site actually ships.
Performance and media
Image compression, width/height, descriptive alt text, Core Web Vitals-aware templates and server-rendered content.
What we implement on the page
A typical on-page engagement starts with the current URL map, indexation status and template inventory. We then fix the page itself: metadata, headings, copy structure, internal links, schema, images, canonicals and sitemap coverage.
When the site is multilingual, we treat each locale as a first-class URL set. Alternate language tags, sitemap xhtml:link entries and translated titles are part of the same job—not an afterthought.
- Unique title and meta description for every indexable URL
- Canonical tags that match the live URL, including trailing slashes
- hreflang + x-default for all published locales
- XML sitemap index with locale page sitemaps, lastmod and language alternates
- JSON-LD that matches visible content (no fake reviews, no invented ratings)
- Internal links from hubs, navigation, footer and related blocks
- Heading structure that a crawler and a reader can follow
- Image alt text that describes the image, not a keyword dump
- robots.txt that points to the sitemap and to llm.txt / llms.txt
How this sits next to web development
New sites should ship with SEO-friendly architecture from web development. On-page SEO optimization is the dedicated pass when an existing site already ranks poorly because titles collide, pages are thin, schema is missing, or language versions are not linked.
After launch, maintenance keeps metadata and content current. On-page SEO is the structured audit and implementation work; maintenance is the ongoing change.
What we will not sell you
We will not guarantee #1 rankings, a traffic number, or a backlink campaign disguised as on-page work. We will not stuff keywords into titles, hide text, or generate doorway pages.
If the honest answer is that the market query is too competitive for the content you have, we will say so and recommend better pages—not a trick.
Typical on-page SEO projects
Corporate and service sites
Service pages that currently share one title, weak H1s and no internal links between offerings.
Multilingual websites
Locale URLs that exist but are not linked with hreflang, sitemaps or translated metadata.
Content-led businesses
Article templates missing Article schema, dates, related links and category hubs.
Ecommerce catalogs
Product and category pages with duplicate titles, thin descriptions and missing breadcrumbs.

FAQ
Questions companies usually ask.
Do you guarantee Google rankings?
No. We implement crawlable, well-structured pages. Rankings depend on search demand, competition, backlinks and the quality of the content you publish.
Is on-page SEO the same as web development?
Related, not identical. Web development builds the site. On-page SEO is the dedicated optimization of titles, content structure, metadata, schema, internal links and indexation on those pages.
Do you work on existing websites, not only new builds?
Yes. Most on-page work is an audit and implementation pass on a live site: colliding titles, missing canonicals, thin service pages, broken internal links and incomplete sitemaps.
Do you cover off-page SEO and backlinks?
This service is on-page. We can advise when off-page work is the actual gap, but we do not sell link schemes.
Can you optimize a multilingual site?
Yes. We implement hreflang, locale sitemaps, translated metadata and consistent URL rules across the languages the website actually publishes.

Need the pages themselves to be search-ready?
Share the live URLs, locales and the queries you actually want to compete for. We will tell you what the pages need—not a ranking promise.
