SEO Auto Linker is an update to the much loved SEO Smart Links plugin.
The plugin automatically links words and phrases in your post, page or custom post type content.
The difference is that you no longer have to try and guess what links will appear. Specify keywords in a comma separated list, type in the URL to which those keywords will link, specify how many links to the specified URL per post, and then specify the post type. SEO Auto Linker does the rest.

I just recommended this to Paul Boag of the Boagworld podcast. It’s that good that after 4 years since last update it’s still working with a WordPress 4.8 I tested it on!
The idea is good to make the task quickly but come on my whole blog was crashed and it shows errors like this :
c505218304b50c59c3659f6dda43bae7-links-7–>c505218304b50c59c3659f6dda43bae7-links-6–>c505218304b50c59c3659f6dda43bae7-links-5–>c505218304b50c59c3659f6dda43bae7-links-4–>c505218304b50c59c3659f6dda43bae7-links-3–>c505218304b50c59c3659f6dda43bae7-links-2–>c505218304b50c59c3659f6dda43bae7-links-1–>c505218304b50c59c3659f6dda43bae7-links-0–>c505218304b50c59c3659f6dda43bae7-header-0–>
so i’m gonna look for the alternative
I’ve tried all plugins available for Internal Linking:
1) ‘Internal Link Building’ by Internet Marketing Ninjas. Problems: Links on Headings. It doesn’t allow to group keywords.
2) ‘WP Optimize’ By xTraffic. Problems: links are changed to bold; you can’t choose taxonomies (it broke my website).
3) ’SEO Smart Links’. Problems: many bad reviews, it has many problems.
4) ‘In-text SEO internal link building’ by NotedLinks. Retired.
5) ‘SEO Auto Linker’ is just the best. Period. You choose taxonomies. It doesn’t link headings. Links are not changed to bold. You can group keywords. Blacklist allow you to add exceptions. You can add nofollow in case you link to external links/affiliates.
Just a word: the best
As far I can see SEO Auto Linker is/was the only plug-in that will do this task quickly.
For my site it will work perfectly for certain words, but other words will break the site completely making it devoid of all text and content.
The words that break it for me are ‘diet’,’external’ and ’causes’.
Of course, if it only works some of the time it renders itself useless.
I really hope the dev can find out what the problem is with this and restore it to it’s fully operational state.
I’ll keep my fingers crossed, because this plug-in was a nugget.
I will just mention, I have spent half a day tinkering with it, trying different settings, etc, even making a second using a URL I know is working via the plug-in, but all to no avail.
Unhappy bunny here 🙁
