Internal Links are most useful for establishing site architecture and spreading link juice . For this reason, this section is about building an SEO friendly site architecture with internal links.

Internal linking of exact match phrases to pages that are required to rank highly seems to be one of the most overused techniques by SEO agencies.

I’m seeing this technique used more and more whenever a website goes through a re-design where SEO has been one of the main goals of the website.

Internal links are links that go from one page on a domain to a different page on the same domain. They are commonly used in main navigation. These type of links are useful for three reasons:

They allow users to navigate a website.
They help establish information hierarchy for the given website.
They help spread link juice (ranking power) around websites.

In the example above, Google’s colorful spider has reached page “A” and sees internal links to pages “B” and “C.” However, even though E & D might be important pages on the site, the spider has no way to reach them because no direct, crawl-able links point to those pages. As far as Google is concerned, they might as well not exist – even if your page has great content for audience ,good keyword research would not make any difference at all if the spiders can’t reach these pages in the first place.

It’s important to only interlink pages where it will make sense to your users and not just to please Search Engine Spiders. For example, it is completely legitimate to link two of your sites together if one site references something on the other because this would make sense to a user as these two pages are related.

Interlink only those pages which are in contrast to the exiting post. DO not link your Android page/article to Photography article or Page.You also risk that someone will report your website for spam links if you are repeatedly including links that don’t make sense to users.

Don’t be afraid to interlink pages of your websites .Interlinking pages and websites is a natural part of website design, development and SEO.

Once you start learning about Search Engine Optimization  it becomes very easy to fall into the trap of “over-optimizing” your websites. This could involve any number of well known techniques that are not bad if used correctly, but if you try to use these techniques to game the system, could have a negative effect on your website.

Interlinking your posts is not just about adding a hyperlink to one of the keywords, for maximum SEO benefit you must follow the three best practices listed below:

Create more links at the beginning section of the post, Links created in the initial section of your post tend to improve your google ranking and search visibility to a greater extent than creating links at the bottom section of the post or in the footer section incluidng the Patner websites and externalBlog .This gives good visibility to readers to move between posts.

Do not link to the same post more than once in each post as search engine algorithms give more credit to one the first anchor text where in case there are 2 links pointing to the same URL.

Don’t do Over-optimization With Linking: Too many links in a post makes your blog look spammy.

Create links to Related Posts – From user perceptive one would like to read your article and turn to related article which will be useful to read.When you interlink content, make sure the context of your post is maintained and that your interlinking efforts make sense.
