SEO Smart Links

Support SEO Smart Links by buying the Premium version!  SEO Smart Links Premium is faster, with bug fixes and over 20 new features. What is new?

SEO Smart Links can automatically link keywords and phrases in your posts and comments with corresponding posts, pages, categories and tags on your blog.

Further SEO Smart links allows you to set up your own keywords and set of matching URLs.

Finally SEO Smart links allows you to set nofollow attribute and open links in new window.

Everything happens completely transparent, and you can edit the options from the administration settings panel.

How it Works?

SEO Smart Links looks for keyword phrases that match the titles of your posts and pages by default (and you can enable categories and tags matching too). These phrases are then turned into the links. The matching is case insensitive and the original case is preserved.

So If I mention Amazing Grace, which is my theme and also the title of one of my pages, it will be automatically converted into a link.

Everything happens completely transparent, and you can edit the options from the administration settings panel.

Features:

  • Find keywords in your posts, pages and comments and link them to your other posts, pages, categories and tags
  • Full control with customizable options
  • Ignore list for keywords you do not want to link
  • Improves your site's interlinking
  • Control external links with custom keywords
  • Add nofollw attribute or open links in new window
  • Caching for speed - make sure you have define('ENABLE_CACHE', true); set in your wp-config.php

    The newest version brings caching so things should be lot better now! BE sure to enable wordpress cache first!

    WordPress is very slow with working with categories and tags due to poor organization of tables, specially on numbers you mention. I admit I do now have any caching yet but let's say the guilt for poor performance is equally shared.

    Hi Vladimir,

    Yes, indeed I did have categories and tags turned on. Would that be the cause of the poor performance? If so, I would still consider that to be a development issue and not an end user issue. Those options should be available without hindering performance from the blog.

    My mistake on the added tables. Although, I am still concerned with performance. The blog I tested SEO Smart Link on is a blog with 700 posts (average post is about 600 words) with around 1000 tags and quite a bit of traffic. When I activated the plugin, immediately the load time of the blog was terribly slow. As soon as I deactivated the plugin load time went right back to normal.

    It can happen that the performance is an issues if you turn on linking of cats and tags too, I guess this is what you did?

    There is no extra table used, all information is saved in WP options table and consumes very little space.

    Great idea and nice alternative to ALinks. However, this plugin really slows down the performance of my blog. Also I noticed the extra table added to my MySQL DB.

    All in all it doesn't seem to be written in a way that will perform smoothly on busy blogs. Perhaps, you can make improvements in the future.

    Like many plugins that modify the MySQL DB, you should provide documentation on how to remove the extra table from MySQL when a user no longer wants to use the plugin. Simply deactivating the plugin from the dashboard doesn't remove the plugin from the WP Install.

    The links appear if you have matches. Try mentioning of of your post titles in your next post and see if it becomes a link automatically.

    I'm having an issue with it. So far I haven't seen any interlinks arise yet. I've had the plugin for a few days now. Can anyone tell me what I haven't done yet. I followed the instructions above but so far nothing =(

    I can announce version 1.2 which is on the way to the repository and adds limits as a new feature.

    That would be a good feature I think.

    I can introduce the number of maximum links per post and maximum links to a single post if that is what you want..

  11. Jun 20th, 2008 1:14 PM

    I like the plugin, but would like to limit the number of links that it creates. Is this possible? Currently it links to the same page about 10 times for one of my blogs, I would ideally like it to only link once to each page, and only have 3 or 4 links per post.

    Cheers

    Jon.

    Yes Yes sir.
    Just downloaded it, and gotta see the links coming up. Guess i gotta play a little with it.

    But i must say it looks very promising. Thanks again and thanks for fast answers :)

  13. Jun 19th, 2008 9:36 PM

    There is a new version 1.1 available that should fix that problem.

    Links appear to your matching posts and pages.
