<h3>Usage</h3>
Here’s how it works:
You’ll find the plugin under the WordPress Settings menu.
Click on the plugin in the settings menu, and a user screen will appear where you can select (via dropdowns) either a single article or an article category target.
Next, you can select whether or not to include a link to your selected pillar post or page. If you choose Yes, select your preferred pillar post or page from the dropdown.
When you click the button to proceed, the plugin works as follows after selecting either a single article or a category.
a)The plugin will retrieve all the articles in the same category as either the single article you selected or the category you selected. 
b)The plugin will randomly select 6 articles in the same category and create an HTML heading and list of linked titles. It then adds this list to either the end of the single article or performs the same action on all articles in the category selected. 
c)If you selected Yes for pillar content, and you’ve selected the target post or page as the pillar, the plugin will proceed to add the title of your selected post or page as a bolded first item of the links list.

100% AUTOMATIC INTERNAL LINKING PLUGIN FOR WORDPRESS. NO NEED TO BE AN EXPERT, 2 CLICKS AND IT’S DONE!
★ ★ ★ ★ ★
You all know that using the right internal linking strategy can boost your SEO! Before your content can rank, it needs links. Internal links connect your content and give Google an idea of the structure of your website. The more links an important page receives, the more important it will seem to search engines. Therefore, good internal links are crucial to your <a href="https://en.wikipedia.org/wiki/Search_engine_optimization" rel="nofollow ugc">SEO</a>.
The Automatic links for SEO plugin is a revolution in the field of internal linking. No need to manually create your links with any other WordPress plugins. This plugin will do it for you, in automatic mode, using Yoast / Rank Math Focus keywords as **<a href="https://www.reliablesoft.net/what-is-anchor-text/" rel="nofollow ugc">anchor text</a> for internal link building.**
How it works (short version)
Once the plugin is installed, take a few minutes to read the few explanations to understand which features to use.
<ul>
<li>Make sure you select the correct options in the “Settings” section. These are generalized to all the functionalities of the plugin (SYNC, AUTO LINKS, INTERNAL / EXTERNAL LINKS), such as for example:
<ul>
<li>Where to apply: if you want the plugin to limit link creation only to pages, articles, products and “custom post types”.</li>
<li>Where to NOT apply: if you want to exclude pages, articles, and others (note that you can also exclude some pages by using the META BOX visible in the SIDEBAR of each of your pages).</li>
<li>Exclude HTML Tags: if you want to limit link creation to your content (by default, H1, H2, H3 tags are excluded)</li>
<li>Priority: if you want the links to be created to override the links already created</li>
<li>Max links: the number of links to create per page (make sure not to create too many, 2 is a good average)</li>
<li>New Tab: if the created links should open in a new window</li>
<li>No Follow: if the NOFOLLOW attribute must be added to created links (not recommended – only for external links)</li>
<li>Partial Match: if the “Anchor text” created can vary depending on whether the word found contains a variation (the plural form).</li>
<li>Case sensitive: if the “anchor text” created must have the same “shape” (capital letters, for example)</li>
</ul>
</li>
</ul>
Once done, you can start synchronization from the **SYNC **button.
Once launched, a log will appear just below showing you all the links being created.
Once finished, if you want to view all the links created by the plugin, simply go to “Activity Log“.
Then you can also create custom links manually by going to the “Custom Manual links” section.
– The “Internal links” feature allows you to create internal links from custom words (anchor text) (other than “focus Keywords”) for existing pages on your website 
– The “External links” feature allows you to create external links also from specific words (Anchor text)
An editable “Log” is available on the same page allowing you to modify each of these “custom” links.
How it works (explanations)?
Automatic Internal links for SEO works from the “Focus Keywords” (META tag Keyword) used with the help of Yoast SEO or Rank Math when creating META data (the titles and descriptions listed by Google when you do a search).
Considering that the words (or combinations of words) used as “Focus Keywords” when you created your META data are important as they represent the theme for which you want your content to be understood by search engines and also that one of the factors that play a role on how valuable a link is, is the anchor text, this plugin will scan your website for these “Focus Keyword” and identify / match the pages, articles, or products where they have been found.
 Then, it will scan the content of your website looking for words or combinations of words similar to these “Focus Keywords” (the plugin offers a certain flexibility in the identification of these words, in particular via some options like “Partial Match, Case sensitive, … ).
Once identified, these will be automatically converted into “anchor text” with a link redirecting to the page to which they correspond.
For example, if you have written a page for which you have defined as “Focus Keyword” the word “Mechanical”, the plugin will scan your website for the word “Mechanical” and once found, it will automatically create a link to the page where this “Focus Keyword” was found. If you subsequently change this “Focus Keyword” to something else, the previously created links will be deleted and new links will be created.
The particularity of this plugin is that the detection of new content created is done on an automatic basis! In other words, the plugin will continuously scan your website looking for new links to create from “Focus Keywords”.
But there is more! Once the plugin is installed, you will be offered 2 options: SYNC & AUTO LINKS.
The SYNC function, from the chosen configuration (Priority, number of links, etc.), without even having to identify anything, will scan your website for “Focus Keywords” and automatically create all the corresponding links. Once done, depending on your activity on the website, the plugin will notify you of the existence of new links to synchronize. This last operation is manual.
The AUTO LINKS functionis 100% automated. In other words, the plugin will automatically detect page updates or new pages created and proceed directly to the creation of the links, without you having to do anything.
Thus, your internal linking strategy evolves at the same time as the creation of your content and will boost your SEO and <a href="https://en.wikipedia.org/wiki/Web_traffic" rel="nofollow ugc">Web traffic</a>.

How does it work with search engines?
Here’s what Google says:
Google must constantly search for new pages and add them to its list of known pages. Some pages are known because Google has already crawled them before. Other pages are discovered when Google follows a link from a known page to a new page.
When Google (or any other <a href="https://en.wikipedia.org/wiki/Search_engine" rel="nofollow ugc">search engine</a>) crawls a website, it does so by following internal links using the Google bot. The bot reaches the homepage of a website (or any other page) and starts following the first link that it comes across on the site. By following such links, it can understand the relationships between different web pages within a website.
<a href="https://en.wikipedia.org/wiki/Internal_link" rel="nofollow ugc">Internal links</a> also give Google an idea of your website structure and that’s the purpose of adding links throughout your content. They help you to build a site hierarchy, allowing you to provide more value to important web pages on your site or blog posts than the rest. A good internal linking strategy allows the distribution of page rank and link juice from one page to another
The perfect example of internal link usage is <a href="https://en.wikipedia.org" rel="nofollow ugc">Wikipedia</a>. If you view any page on Wikipedia you will immediately notice that they are using tens of internal links (with keywords as the anchor text) and guess what? Wikipedia appears very often on top of search engine results pages … !
Google Recommendations on Internal Links : Matt Cutts (former head of the Google Quality team) in this video confirmed that internal links are treated differently from external links and provided that you are not doing any exaggerations (for example having more than 100 links per page), you don’t have to worry that you are violating Google webmaster guidelines.

What are internal links?
Internal linking is essential to any website because it helps establish site architecture and spread the link juice. An internal link is any link from one page on your website to another page on your website. Both your users and search engines use links to find content on your website. They won’t find a page if there are no links to it.
Why is internal linking important?
For a very simple reason. Just because you post content on your website doesn’t mean it is:
– Directly available in search engine results 
– Accessible & Indexable by search engines
And this, even if your website has an up-to-date sitemap.
For content, whatever it is, to be crawled by search engines, then indexed and ultimately to generate SEO, it must be accessible through the internal linking! In other words, crawlers, moving from link to link on your website, must be able to access it quickly.
But this is usually where two major obstacles prevent crawling and indexing of this content (and this is one of the biggest SEO issues) on millions of websites: (too) deep pages and orphaned pages.
Deep pages (also called “weak pages”) are pages too deep in the structure of your website that  struggle to be discovered and crawled on a regular basis by crawlers, which decreases their importance (at search engine eyes) and therefore decrease the likelihood that they generate SEO.
Orphaned pages are also a common problem. These are pages identified as existing by crawlers, from your sitemaps, but which cannot be found by search engines, via internal links. These are therefore pages that will not generate any ranking on search engines.
An automatic internal linking solution will allow you to flatten your URL structure so as to make all of your content much more accessible by search engines and therefore more likely to generate SEO. Moreover, internal link building has several other advantages as it helps build page authority, usability, connections between web pages, user experience, and more important, an efficient Google ranking.
Internal links vs external links
Every website consists of internal and external links. Internal links connect pages and posts on your own website and external links connect your pages to other websites
