SEO Alt Tag Optimizer & Font Resizer Tool (WordPress plugin)

7th June 2007

SEO Alt Tag Optimizer is a WordPress plugin that enables a website owner to make optimum use of the Image ALT tags to improve the site’s search engine rankings through the effective utilisation of established and proven search engine optimization techniques.

This plugin creates three small icons (images) on every page of your WordPress site, and populates these image’s ALT tags with different combinations of the following relevant key-phrase and keyword terms:

  • Your WordPress Site Name
  • Your WordPress Site Description
  • Your WordPress Page Title (if you are on homepage, category page, archive page or static page)
  • Your WordPress Post Title (if you are on a single post page)
  • The Ultimate Tag Warrior [UTW] tag name (if the UTW plugin is installed and when on a UTW tag page)

The uniqueness of this plugin is that the three SEO-optimized images (small icons) are also used to allow your web site visitors to increase the font size, decrease the font size or to return the font size back to the default size. This assists any visitor with accessibility difficulties to read the content of your web site without having to change their own browser’s viewing settings.

So in summary, not only does this plugin help to increase your Search Engine Optimization (SEO) score by up to 5%, but it is also a fully working font resizing tool.

To improve your SEO rating, it is best to place this plugin in order of preference as detailed below:

  1. Include the plugin in your header area (i.e. call the plugin from within your header.php file), or
  2. Include the plugin at the top of your sidebar (i.e. call the plugin from within your sidebar.php file), or
  3. Include the plugin in the footer area (i.e. call the plugin from within your footer.php file)

The placement of this plugin in the Sidebar and Footer can be seen in the diagrams below.

Frequently Asked Questions

Q1. How will the search engines rank my site better if I use this SEO plugin?

A1. Most of the major search engines (e.g. Google, Yahoo, Microsoft Live) look at the ALT text linked to the images on each page. If the search engines find that your image’s ALT text is relevant to the content of the page (i.e. use the same key-phrases and key-words) then they increase your SEO score by up to 5%. Why up to 5% and not 5% exactly? Well, this depends on the quantity of images you have on each page. If you have only 3 images per page (i.e. only the 3 icons generated by this plugin) then you will increase your SEO score by around 5% (this percentage differs depending on the search engine’s own algorithm) - whereas, if you have 4 or more images on a page, then your score will be increased in proportion to your total quantity of images with relevantly tagged ALT image text. It is also recommended to have these 3 images as near to the top of your page code as possible as the search engines usually score against the first three images it finds as they index from top-left to bottom-right of each page.

Q2. I have followed the Installation and Configuration steps above and no images are showing - or the ALT text is showing instead?

A2. You may have installed the 3 image files to the incorrect folder, i.e. the ‘Images’ folder needs to be under your ACTIVE template. Also you need to give at least 744 permissions to each of the image (jpg) files.

If you are using the ‘Classic’ WordPress theme (or another WordPress Theme that does not have its own ‘Image’ folder directly under the theme folder) then you will need to comment out line 49 of the seo-alt-tag-optimizer.php file

i.e. //$frtimage_path = get_bloginfo(’template_directory’) . ‘/images/’;

and uncomment line 52 with the path to your own Images folder

e.g. use $frtimage_path = get_bloginfo(’url’) . ‘/images/’;

or even, $frtimage_path = ‘http://www.your-own-blog-domain.com/images/’

Q3. I can see the images, but nothing happens when I click on the Increase or Decrease images?

A3. As this Font Resizer Tool is written in JavaScript, the browser must have JavaScript enabled, and if using Internet Explorer, you need to add the site’s domain to the visitor’s Trusted Sites list.

Additionally, you may have the wrong path set to the ‘font-text-resizer.js’ file in your header.php. Make sure that this path is correct and this file has at least 755 permissions to read and execute this file. Try to copy this file to your /wp-includes/js/ folder as all the JavaScript folder permissions are set correctly. But remember to update your header.php file to point the script to this new folder path.

To further test this plugin, try to enter the full URL path to the images and JavaScript files to make sure that all paths and permissions are set correctly.

Also, view the source code of the page and if you see a line of code similar to the format below, then the problem lies with the permissions to the JavaScript (.js) file and not the plugin (.php) file:

img src=”http://www.indiana-loans.co.uk/wp-content/themes/fallseason-11/images/decrease-font-size.jpg” onclick=”fnChangeFontSize(’body’,-1);” alt=”Decrease font size for Page - Indiana Loans Limited - Provider of secured loans for UK small businesses, self-employed & individuals” title=”To reduce font size, please enable JavaScript and Trust this Site” border=”0″ height=”14″ width=”18″

If you cannot view the line above in your pages source code, then you either need to activate this plugin in the WordPress Administrator Plugin panel, or again, check that file permissions are set to 755 for the seo-alt-tag-optimizer.php file.

Q4. The Font Resizing works, but the format of the page looks all funny when I increase or decrease my font size?

A4. The font resizing tool uses JavaScript and behaves in exactly the same way as the browser when you go to your View menu option and selecting to either increase or decrease the font size. What determines how fonts are displayed is that specific sections of your page are controlled by your CSS template file (style.css). If you have a comprehensive CSS template file, then you web site format should not misbehave too badly. If you use fixed font sizes (e.g. font size=”2″ and not font size=”100%) then this tool, nor your browser, will be able to change the font sizes when using the fixed font size type. Please remember that this plugin is really here to improve your SEO ratings in the search engines!

  • Excellent plugin. I have studied my SEO reports since activating this plugin and they do indeed show a marked improvement of my SEO score as my blog now displays three images with very relevant key-word and key-phrase ALT tags.

  • [...] You can see a preview and download this plugin from here. [...]

  • Hello,

    The plugin sounds great, but I’m getting the fowlling error:
    Fatal error: Call to undefined function: is_tag() in /home/ppp/public_html/wp-content/plugins/seo-alt-tag-optimiser/seo-alt-tag-optimizer.php on line 92

    Btw, I need to have Ultimate Tag Warrior Plugin v3.14+ installed or its just “tested with”?

    Rui

  • Hi Rui,

    Thanks for reporting the bug. I have now fixed this bug in version 1.1.

    This bug was due to the fact that the is_tag() function needs the Ultimate Tag Warrior plugin to be installed for it to execute properly.

    I have added an ‘if clause’ to not run the is_tag function when UTW is not installed.

  • Hello!
    A great plug-in. Took a while to get working, but I think that was my hosting more than the coding!

  • Perfect plugin, thank you so much! It’s exactly what I needed.

    :)

  • Hello Indian Loans,

    I’m Gaurav, I’m basically interested only in ‘ SEO Alt Tag Optimizer ‘ and not in Font Resizer.

    So will it be OK if I upload only seo-alt-tag-optimizer.php and activate it without Font resizer.

    I want your kind guidance as I know alt tags can really prove useful to increase SEO Rankings.

    Do reply.

  • Hi Gaurav,
    You are free to use the code as you wish, but the code is written for three images, so you will need to decide on alternative images. If you do not want to use the Font Resizing feature then you just omit the onclick code that lies beneath each image.
    My only recommendations, is to try to use three different image sizes (and not 1×1 pixels) as the search engines may pick up that you are trying to key-word pack your pages. Also try to only use up to three images per phrase or keyword, and try to keep your images to top-left of the page so these images are read by the spiders first.
