Sets the title and alt attributes automatically - important for search engine optimization

The title and alt attributes are important for search engine optimization, but unfortunately they are not respected very often. The plugin checks all links and images on these attributes. If they are not set, they are generated from the linked text or from the image name. Additionally there is the possibility to overwrite existing attributes with the automatically generated one.

I wish you much success in the optimization of the website! Please support my work and the free availability with a donation if the extension brings you an added value.

Features

Auto-completion and setting of relevant attributes for links and images
Set title attribute for links (generated from the linked text)
Set alt and title attribute for images (generated from the image name)
Add height and width to the images
Already existing values can be overwritten
Deactivate the plugin in editor mode
Deactivate the plugin in certain components
Languages: English and German

Installation

Install the plugin in the backend, then adjust and publish it in Extensions - Plugins - System - SEO Friendly Links and Images.

Usage

The plugin optimises the requested page automatically. There is no further intervention required!

Tip: If other system plugins are used to manipulate the output, then SEOFLI should be executed as the last instance.
