    return [
        'seo' => [
            'class' => 'yiier\seo\SeoModelBehavior',
            'names' => [
                'viewport' => function (self $model) {
                    return $model->title . ', tag1, tag2';
                },
                'keywords' => 'blog,forecho',
                'author' => 'author', // model field
            ],
            'properties' => [
                [
                    'property' => ['title', 'og:title'],
                    'content' => function (self $model) {
                        return $model->title . ', tag1, tag2';
                    },
                ],
                'title1' => 'title',
                [
                    'property' => 'description',
                    'content' => function (self $model) {
                        return $model->title . ', tag1, tag2';
                    },
                ],
            ],
        ],
    ];
}

PHPdoc for model:

/**
 * @property \yiier\seo\SeoModelBehavior $seoBehavior
 * @method \yiier\seo\SeoModelBehavior getSeoBehavior()
 */

Change /frontend/views/layouts/main.php:

<?php
/* @var $this \yii\web\View|\yiier\seo\SeoViewBehavior */
?>
<head>
    <!-- Replace default <title> tag -->    
    <title><?= Html::encode($this->title) ?></title>
    <!-- by this line: -->    
    <?php $this->renderMetaTags(); ?>
    ...
</head>

Usage

In "view.php" file for model:

// set SEO:meta data for current page
$this->setSeoData($model->getSeoBehavior());

or in controller:

 Yii::$app->view->setSeoData($model->getSeoBehavior());

Simple url rules example in '/frontend/config/main.php':

'urlManager' => [
    'enablePrettyUrl' => true,
    'showScriptName' => false,
    'rules' => [
        '<controller:\w+>/<action:\w+>/<id:\d+>' => '<controller>/<action>',
        '<module>/<controller:\w+>/<action:\w+>/<id:\d+>' => '<module>/<controller>/<action>',
        'post/<action:(index|create|update|delete)>' => 'post/<action>',
        'post/<title:[-\w]+>' => 'post/view',
    ],
],
