Generates SEO metadata based on page content using AI. Currently, meta description, keywords, page title, Open Graph and Twitter data (titles and descriptions) of the page properties can be generated. Based on page title and meta description you can fill Open Graph title, Twitter title, Open Graph description and Twitter description too.

Furthermore, alternative title suggestions, description suggestions and keywords can be generated for articles of EXT:news.

By using an additional button next to the corresponding input fields you can generate the specific suggestions/data.

The extension currently supports the GPT-3.5 models and GPT-4 models. No snapshots of models are supported. Please also note possible restrictions when using the "GPT-4" models (see Possible limitations when using the GPT-4 model).

Based on your individual requirements, different models can lead to different results (also in terms of quality). In addition, other parameters can be modified to further specify the OpenAI requests. You have the possibility to adjust the different models as well as the most of the supported request parameters (detailed explanation can be found here) in the extension settings.

Added an additional button next to the meta description text field. When you click this button, the (text) content of the selected page is generated, and you get meta description suggestions with the help of the AI. By default, the extension prepares the meta description suggestions in such a way that they can be selected via radio button. If you change the prompt prefix and no bullet point list is returned as a result, display problems can occur here. If you set the option showRawMetaDescriptionSuggestions to true within the extension configuration you can output the raw content and select your favorite meta description via copy/paste.

It can happen that the AI returns texts that exceed the maximum allowed length of the meta description. To additionally check the length of the meta description, the extension "Yoast SEO for TYPO3" can be used, for example, or various online tools.

Added an additional button next to the keywords text field. When you click this button, the (text) content of the selected page is generated and keywords that is as suitable as possible is created with the help of the AI. Currently, the page must not be deactivated in the backend. Depending on the page size, the process may take a few seconds. However, notifications are used to display appropriate information.

If you set the option showRawNewsAlternativeTitleSuggestions to true within the extension configuration you can output the raw content and select your favorite page title via copy/paste.

Since version 0.3.0 you have two different options to generate the desired data. Both variants adds a "language suffix" to get the response in the language of the analyzed page/content.

As already mentioned, this option is primarily limited by the length of the allowed characters per OpenAI request. Furthermore, using this method requires the use of a comparatively large number of tokens.

The following settings are necessary:

• disable the useUrlForRequest option in the extension settings
• check if the ISO code(s) of the language configurations is/are present in the predefined fields (if not present, custom languages can be added, see "Add custom languages").
• Definition of the corresponding prompt in English.

The entire prompt is then assembled from the prompt prefix (from the extension settings), the page url and the language suffix (based on the language used on the page). An example of the generated prompt for page title suggestions would look like this (for a German language site):

1. Suggest page title ideas in bullet point list for the following text (content from extension setting `openAiPromptPrefixPageTitle`)
2. in German (language suffix based on the language used on the page)
3. Here comes the page content

Complete:

Suggest page title ideas in bullet point list for the following text in German:

Here comes the page content

In contrast to the text-based variant, this option uses the URL of the page to analyze the desired data. If you want to use this variant, the following settings are necessary:

• enable the useUrlForRequest option in the extension settings
• check if the ISO code(s) of the language configurations is/are present in the predefined fields (if not present, custom languages can be added, see "Add custom languages").
• Definition of the corresponding prompt in English.

The entire prompt is then assembled from the prompt prefix (from the extension settings), the page url and the language suffix (based on the language used on the page). An example of the generated prompt for page title suggestions would look like this (for a German language site):

1. Suggest page title ideas in bullet point list for (content from extension setting `openAiPromptPrefixPageTitle`)
2. https://www.example.de/ (page url)
3. in German (language suffix based on the language used on the page)

Complete:

Suggest page title ideas in bullet point list for https://www.example.de/ in German

Requirement is that the page is publicly accessible (hidden pages fail and pages in a local environment lead to poor results).

A major advantage is that this variant saves quite a lot of OpenAI tokens (and thus costs), since only the URL is sent to OpenAI instead of the entire page content

You can adapt the following parameters to your personal needs. After the first tests, the best results were achieved with the predefined values. However, this is no guarantee that these values will also achieve the best results for you.

# cat=API Key; type=string; label=OpenAI Secret Key
openAiApiKey = YOUR_API_KEY

Enter your generated OpenAI API key.

# cat=basic request settings; type=string; label=OpenAI Model
openAiModel = gpt-3.5-turbo

The id of the model which will generate the completion. See models overview for an overview of available models.

# cat=basic request settings; type=double+; label=OpenAI Temperature
openAiTemperature = 0.5

What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.

# cat=basic request settings; type=int+; label=OpenAI Max-Tokens
openAiMaxTokens = 275

The token (what are tokens and how to count them) count of your prompt plus max_tokens cannot exceed the model's context length. Most models have a context length of 2048 tokens (except for the newest models, which support 4096).

# cat=basic request settings; type=int+; label=OpenAI Top-P
openAiTopP = 1

An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.

# cat=basic request settings; type=double; label=OpenAI Frequency Penalty
openAiFrequencyPenalty = 0.8

Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.

# cat=basic request settings; type=double; label=OpenAI Presence Penalty
openAiPresencePenalty = 0

Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.

With this option you can use the corresponding URL of the page for all analyses. As a result, you have to use fewer tokens to carry out your corresponding analyses. IMPORTANT: The page must be publicly accessible (hidden pages fail and pages in a local environment lead to poor results)

The root page of the page to be analyzed is determined. Based on this, the ISO code used (the iso-639-1 field of the corresponding language from `config.yaml) is determined. The corresponding language has already been created for the conventional ISO codes. The following ISO codes and languages are already stored:

• 'en' => 'English',
• 'us' => 'English',
• 'gb' => 'English',
• 'de' => 'German',
• 'at' => 'German',
• 'ch' => 'German',
• 'fr' => 'French',
• 'nl' => 'Dutch',
• 'be' => 'Belgian',
• 'es' => 'Spanish',
• 'pl' => 'Polish',
• 'cz' => 'Czech',
• 'sk' => 'Slovak',
• 'si' => 'Slovenian',
• 'ro' => 'Romanian',
• 'ua' => 'Ukrainian',
• 'it' => 'Italian',
• 'se' => 'Swedish',
• 'no' => 'Norwegian',
• 'fi' => 'Finnish',
• 'dk' => 'Danish',
• 'jp' => 'Japanese',
• 'cn' => 'Chinese'

If the desired ISO code and language is not contained, it can be created using a data record "Custom language". The user-defined languages are added automatically (already existing languages are replaced by user-defined languages).

Of course, the functionality can also be transferred to other page properties that are not currently taken into account. The following procedure applies to all text input and textarea fields. Additional adjustments must be made for other fields (e.g. image fields) or fields within content elements.

Do not make the changes directly in the extension! Please create your own extension for individual adjustments or add the changes to your sitepackage extension and add/edit the following files:

The following placeholders were used:

• FIELD_IDENTIFIER: identifier of the field (e.g. twitter_title),
• FIELD_IDENTIFIER_UPPER_CAMELCASE: identifier of the field in upper camel case (e.g. TwitterTitle),
• NODE_IDENTIFIER: identifier of the field type of NodeFactory (e.g. aiSeoTwitterTitle)
• TIMESTAMP: current timestamp as a unique identifier
• \Vendor\Package: replace this with your own vendor and package name

    ],
];

Once all adjustments have been made, flush the TYPO3 and PHP cache and test if everything works as desired.

If something does not work as expected take a look at the log file first. Every problem is logged to the TYPO3 log (normally found in var/log/typo3_*.log)

Just like this extension, OpenAI is still in development mode and not fully mature. For this reason, we urgently advise you to check all generated texts for correctness before saving them and to make any necessary adjustments!

The OpenAI API (currently) limits the maximum number of tokens per request depending on the model used (currently the maximum possible tokens are 32,768 by using the gpt-4-32k model). You can find a detailed overview of models and the maximum number of tokens here:

https://platform.openai.com/docs/models/

Based on the current status of the extension, it is unfortunately not yet possible to analyze larger texts.

At the time of version 0.6.0 release, only people with a $1 or more successful payment on their account have access to the GPT-4 model. According to OpenAI, that should change soon.

If you try to use the GPT-4 model without access you currently get a 404 error message which is a bit confusing.

I'm grateful for any feedback! Be it suggestions for improvement, extension requests or just a (constructive) feedback on how good or crappy the extension is.
