Which SEO basics do top homepages have?

Most have the essentials, fewer have the extras. We opened the homepage of each of the 1,000 most-visited domains on the Tranco list and read its search and sharing tags, headings and structured data. Of the 567 working homepages, nearly all set a title, a language and a mobile viewport; 89% have a meta description, 77% a canonical link and 52% structured data.

How long are homepage titles?

The median is 46 characters, and half run between 25 and 60. 136 of 566 (24%) are longer than 60 characters, the figure often quoted as a limit, and 166 (29%) are shorter than 30. Google's own guidance sets no number: "there's no limit on how long a <title> element can be", and a long title is cut in results to fit the device width.

78% of titles include the site's name. The most common separator between a page name and the brand is a vertical bar (195 titles), then a dash (160). 73 titles (13%) are a single word: Google, YouTube, Facebook and Instagram title their homepages with their name alone. On 25 of the 538 homepages whose server HTML we could read, JavaScript changed the title or supplied it.

Do top homepages have meta descriptions?

Most, not all. 64 homepages (11%) have none. The 503 that do run a median 146 characters; 127 (25%) are longer than 160 and 36 shorter than 70. Google again sets no limit: "there's no limit on how long a meta description can be", but the snippet is cut to fit the screen, and Google may write its own from the page text. On at most 18 of the 538 homepages whose server HTML we could read, the description appears only after JavaScript runs.

How many H1 headings do homepages use?

167 of 567 homepages (29%) have no H1 at all. 327 (58%) have exactly one, and 73 (13%) have two or more. The homepages with one H1 tend to look after the other basics too: 94% of them have a meta description, against 75% of those with none.

How many homepages use structured data?

About half. 293 homepages (52%) carry JSON-LD structured data; 69 use the older microdata format. The most common type is WebSite, on 191 homepages (34%): Google's site name documentation says WebSite structured data on the home page is the most important way to state which site name it should show above results. 207 (37%) mark up an Organization or one of its subtypes, which Google's Organization documentation says can help it understand the organization and choose its logo; 142 have both. On 9 of those 538 homepages, the structured data appears only after JavaScript runs.

Do top homepages set social preview tags?

Most do; nearly a third don't. 74% set an Open Graph title and 69% an Open Graph image, the tags social apps and messengers read to build a link preview. 313 (55%) set a Twitter/X card, 248 of them the large-image kind. 225 homepages (40%) list hreflang alternates for other languages or countries, a median of 15 each.

What this means for your homepage

• Write a title for people, not a character count. Google sets no limit; the biggest sites' titles run a median 46 characters and 78% include the brand.
• Give the homepage a meta description. 89% of top homepages have one; Google may still rewrite it, but without one it writes the snippet from the page text.
• Use one H1 for the main heading. It's what 58% of top homepages do.
• Add WebSite and Organization markup. They're the two types Google documents for the homepage, and only 25% of top sites have both.
• Set an Open Graph image. Without one, a shared link may show no picture.

How we ran the study

Sites. The 579 working homepages found among the 1,000 highest-ranked domains on the Tranco list ZJ8PG in our homepage video study, a list built for research (Le Pochat et al., NDSS 2019). On this visit 12 failed to load or answered with an error or a bot check, leaving 567.

Crawl. On October 29, 2026 we opened each homepage in headless Chromium driven by Playwright at a desktop size of 1366 x 900, waited four seconds and read the page's title, meta description, canonical, robots and viewport tags, html lang, hreflang links, Open Graph and Twitter card tags, H1 headings and every JSON-LD block, flattening @graph lists into their types. We also kept the HTML the server sent, to see what changed once JavaScript ran; for 29 homepages that HTML came back empty or as a bot-check page (HTTP 202), so those comparisons cover the other 538. Lengths are counted in characters after trimming spaces.

Checking the crawl. We re-fetched a random 20 homepages with a plain HTTP client instead of the browser: 17 answered, and the title and the presence of a meta description matched the crawl on all 17. One of the 567, digicert.com (rank 71), showed an Imperva bot-check page to the browser as well and is the only homepage counted without a title; leaving it out would change none of the percentages on this page. None of the sites reviewed or endorsed this study.

Part of a series. The same top-1,000 domains feed six studies, each from its own visit: homepage video, social media links, homepage SEO, third-party tools, AI crawlers in robots.txt and fonts.

Limitations

• Domains, not companies. One company can appear several times, and some domains are services or login pages rather than marketing homepages.
• Homepages only. Inner pages often carry different titles, descriptions and markup.
• Tags, not results. We record what each homepage sets, not what Google shows or how the page ranks.
• One visit, on desktop, from the U.S. Sites can serve other tags by country, language or device.
