SEO basics for a corporate website: Speed, structure and content

SEO on a corporate website is the whole of technical, structural and content adjustments made so that the site can be found and understood by search engines, and is fast and trustworthy for visitors. Three foundations determine visibility: speed, page structure and content. As in the YazSis Web Design approach, all of them are planned together with the design.

SEO is often thought of as a job to be added after the site goes live. Yet heading hierarchy, page structure and speed are decisions made at the design stage; fixing them later is both expensive and incomplete. Here is an honest warning too: no agency or software can promise a specific ranking in search. What can be done is to make sure the site fully meets the conditions needed for visibility.

Speed: the visitor lost before the page opens

A page that opens slowly is abandoned without its content being read. Search engines also take into account indicators such as Core Web Vitals, which measure user experience: when the main content of the page appears, how quickly it responds to user interaction, and whether the layout shifts while the page loads. These are not just technical measurements; they also determine whether the visitor will trust the site. For a fast site, look at the following:

• Images: They should not be loaded larger than needed; modern formats should be used and images outside the screen should load late.
• Lightweight components: Unnecessary libraries and scripts loaded on every page should be cleaned out. Every piece of unused code adds to the opening time.
• Fonts: Using a limited set instead of many fonts and weights reduces loading time and visual shift.
• Mobile performance: A site that looks fast on desktop may be slow on a phone. Measurement must be done under mobile device conditions.

Structure: how does a search engine read a page?

A search engine reads a page not visually but through its code structure. The order of headings, tags and links tells it what the page is about. On the technical side, here is what to check:

1. Heading hierarchy: Each page should have a single main heading (H1), with subheadings (H2, H3) under it in a logical order. Heading tags should be used to divide the topic into sections, not to enlarge text.
2. Page title and description: Each page should have its own title and short description that describe the topic accurately.
3. Clear addresses: Page addresses should be readable and permanent; if content is moved, old addresses should be redirected.
4. Internal links: Related pages should be linked to each other with meaningful link text; use phrases that describe the topic instead of “click here.”
5. Sitemap and crawl rules: The files that show a search engine which pages to crawl should be kept up to date.
6. Image descriptions: Images should have meaningful alt text; this matters both for accessibility and for image search.

Content: answering the visitor’s question

A common problem on corporate sites is that the content is devoted to the company talking about itself, while the visitor’s real question goes unanswered. A good page is one where it is clear from the start which question it answers. The following habits make content clearer both for people and for search engines:

• Let each page focus on a single topic and a single visitor intent.
• Let the first paragraph define the topic directly and answer the question right away; AI-assisted search tools also bring this kind of clear answer forward.
• Write frequently asked questions in a separate section, with real visitor questions.
• Avoid exaggerated claims, unprovable adjectives and meaningless keyword repetition.
• Keep content up to date; outdated product, pricing and service information damages trust.

Common mistakes on corporate sites

• A home page with only a slogan and an image; no descriptive text a search engine can read.
• Product and service pages made up of a one-sentence description and a “contact us” button.
• Important information found only in a PDF or an image; because it has not been turned into text, it is neither searchable nor accessible.
• The same text repeated on several pages; it becomes unclear which page answers which question.
• A new page opened for every new topic without thinking about the site’s structure, leaving pages disconnected from each other.

Mobile and accessibility are not a separate topic

A significant share of visitors come to the site from a phone. A fully responsive design means not only a consistent experience on iPhone, Android, tablet and desktop, but also readable text size, sufficient color contrast and links that are easy to tap. An accessible site serves not only users with disabilities but all visitors better, and it indirectly supports visibility in search as well.

Where to start?

1. Measure your current site on a mobile device and list the slowest pages.
2. Check each page’s heading hierarchy, page title and description.
3. Rewrite your most visited pages around visitor questions.
4. Update the sitemap and internal links.
5. Monitor the effect of the changes with search console and analytics tools.

If you are planning a new site, the most efficient way is to settle these topics at the design stage. In YazSis web design, discovering the brand and goal, validating the page architecture with a prototype, and measuring and improving performance after launch are the three main steps.
