Google prefers valid HTML and CSS

Search engine optimization can only be done using HTML text, not suitable for search engines: "Text" in Flash pages, images and videos:

Search engine optimization can only be done through text. If you don't offer HTML text on your website, no search engine will know what you're trying to convey to your visitors. Images, videos, Flash objects and the like are not "content" for search engines.

a lot of text, little formatting code ... and the HTML text right at the front:

Web pages should contain as much visible HTML text as possible in relation to formatting code. You can reduce the amount of formatting code by using CSS attributes for formatting and outsourcing the CSS information to a central CSS template file. Javascript functions also belong in an external file. Give the search engine robots a hand and place your text at the very front of your pages, i.e. as high up as possible in the HTML source text. Information on this point can be found here: search engine friendly web design with CSS.

You can use the Lynx text browser to see which text a search engine recognizes on your site. Online services such as the Seekbot analysis. (The service has unfortunately not been available for some time, probably because of the Seekport bankruptcy. Hopefully the team will continue under a different flag as intended.)

Search engines do not evaluate HTML comments.

Use regular HTML, if possible work with the HTML source text editor:

Anyone who values ​​their pages with texts and links from Google & Co should use regular HTML. Here's how to make your Check HTML files according to the rules of the W3C. You are on the safe side if you acquire knowledge of HTML and a source code editor such as Phase 5 because you have the best overview of your HTML source code with a source code editor.

Older versions of Wysiwyg editors such as Microsoft Frontpage, Adobe GoLive, NetObjects Fusion, Namo Webeditor etc. do not produce valid HTML. The only reason the users do not notice this is because most browsers are as gracious as they are patient and can often also evaluate invalid HTML code. As far as I know, only newer versions of the market leader Macromedia Dreamweaver (now taken over by Adobe) of all Wysiwyg editors are able to generate correct HTML.

Ultimately, the time it takes to familiarize yourself with the operation of a Wysiwyg editor is better spent with familiarizing yourself with HTML. As a German HTML standard reference work, introduction, instructions and command evidence applies Selfhtml. You can also download Selfhtml (approx. 8.4 MB).

Search engine optimization and frameset pages:

It is often claimed that frameset pages are not suitable for search engine optimization, with the same pseudo "arguments" always appearing, so that one has the impression that one is copying from the other without one of these "experts" ever bothering himself would have made to optimize a frameset page for search engines.

The fact is that frameset pages can be optimized for search engines with success if one observes a few special features. It is considerably less time-consuming to optimize an existing website with frames for search engines than to first convert it to a single-page design and then optimize it.

However, single-page design should be used for new projects, not only because search engine optimization is easier to perform, but also for reasons of accessibility.

not suitable for search engines: "Text" in Flash pages, images and videos:

Images, videos, Flash objects and the like can be valuable additional information for your visitors and increase the attractiveness of your website. In addition to your text, you can also use individual embedded Flash objects as a visual eye-catcher. However, images, videos and Flash objects can never replace text and are not "content" for search engines: the "text" and "links" contained therein cannot be recognized by search engines.

Well-known cult sites such as were completely developed with Flash. However, to optimize your completely unknown new web project, you need texts and links that are recognizable for search engines.

Anyone who does not want to do without pages completely developed with Flash, but at the same time values ​​being recorded by search engines, has to go two ways, which inevitably results in double the effort. Here you will find tips on Search engine optimization of Flash pages.

Search engines and images: no image recognition possible:

Images (JPG, GIF and PNG files) are just as "black box" for search engines as Flash objects. A website that contains only images and no text can never get a good ranking in search engine hit lists. It is therefore important to provide HTML files that contain images with the appropriate text and to include the search term in the name of the image file and in the -attribute of the -tag.

So far, search engines have not been able to recognize image content (that may come): So if you have the image of a donkey but also name it, enter "ox" in the attribute, describe an ox in the text of the HTML file, as title and If you use the heading "ox" and make sure that the page with the link text "ox" is often linked, you have a good chance that your page will be placed at the top of the Google search for "ox". This not only applies to the preset text search ("Web"), but also to the "Images" search. Because Google cannot recognize that the animal shown is a donkey.
