        static::retrieved(function (Model $model) {
            app()->make('laravel-seo-meta-box')->addObjectOnPage(get_class($model), $model->{$model->primaryKey});
        });
    }

    public function seo()
    {
        return $this->hasOne(Seo::class, 'object_id')->where('type', static::class);

It seems like hasOne() must be provided by classes using this trait. How about adding it as abstract method to this trait?
