Titel:
Chemistry
Länge: 9 Zeichen; Beste Länge: 10 ~ 60 Zeichen

Der HTML-Titeltag ist eines der wichtigsten Elemente der On-Page-SEO und erscheint in Suchergebnissen, Browser-Tabs und Lesezeichen.

Ihr Titel-Tag scheint nicht die ideale Länge zu haben.

Die Suchergebnisse von Google kürzen Titel, die länger als 60 Zeichen sind. Die Suchergebnisse von Bing kürzen Titel, die länger als 70 Zeichen sind.

Hier sind die Best Practices für Meta-Titel:

  • Beschränken Sie sich bei der Titellänge auf 10–60 Zeichen.
  • Machen Sie Schlüsselwörter/Schlüsselphrasen deutlich
  • Integrieren Sie relevante Power-Wörter
  • Seien Sie klar, aber präzise
Meta-Beschreibung:
Learn about chemical reactions, elements, and the periodic table with these resources for students and teachers.
Länge: 112 Zeichen; Beste Länge: 50 ~ 160 Zeichen
Meta-Schlüsselwörter:
Länge: 0 Zeichen; Beste Länge: 10 ~ 255 Zeichen

The length of your meta keywords seems to be outside the recommended range. Ideally, a meta keywords should be between 10 and 255 characters, including spaces.

Meta keywords are a specific type of meta tag that appear in the HTML code of a web page. They provide information to search engines about the topic of the page. Meta keywords were once used to help rank web pages in search engine results. However, due to the abuse by webmasters and marketers, Google claims to have stopped using them more than a decade ago. Despite this, there are still reasons to consider using meta keywords:

  • Uncertain Impact on Google's Algorithm: While Google devalued meta keywords, it is uncertain if they were entirely removed from its ranking algorithm. Google keeps its ranking algorithms top secret to deter people from gaming the system.
  • Other Search Engines and CMS: Other search engines like Yandex, Baidu, and Naver may still use meta keywords. Additionally, some internal CMS search systems, such as SOLR and Algolia, also utilize the meta keywords tag.

Best practices for Meta Keywords

  • Relevance is Key: It is crucial to choose keywords that accurately reflect the content of your page.
  • Keep it Limited: It is generally recommended not to exceed more than 10 meta keywords for a single page. Also, the content length should not exceed 255 characters (including spaces).
  • Consider Long-Tail Keywords: Long-tail keywords are more specific and longer phrases that target a niche audience. These keywords can be highly effective in driving targeted traffic to your website.

Remember, meta keywords are just one aspect of search engine optimization (SEO), and search engines now place less emphasis on them compared to other factors. However, by following these best practices, you can still optimize your meta keywords effectively and improve the visibility of your web pages.

H1 Tag:
Chemistry
Länge: 9 Zeichen; Beste Länge: 10 ~ 255 Zeichen

The length of your H1 tag seems to be outside the recommended range. Ideally, an H1 tag should be between 10 and 255 characters, including spaces, and remember to use only one H1 tag per page.

The H1 tag in HTML is the main headline users see first when a page loads. It conveys the page's topic, enticing visitors to read further. H1 tags are crucial for SEO, user experience, and accessibility. They distinguish the main title on a webpage, aiding search engines and users in understanding the content.

Here are best practices for H1 tags

  • Use H1 tags for page titles.
  • Limit to one H1 tag per page.
  • Keep H1 tags short and concise.
  • Structure headings hierarchically.
  • Include your main keyword.
  • Ensure H1 tags are engaging.
