2. Backlink Profile

The Backlink Profile of a site is the collection of links that drives and directs the users to it. 

It includes anchor texts, referring domains, referring backlinks, referring pages, spam score, link status, link quality, etc.

Having an excellent backlink profile helps you achieve higher rankings and achieve desired results. 

3. Link Building

Link Building is the process of generating backlinks to a site from other websites, preferably of a higher authority.

It helps a site increase the count of backlinks, which in turn improves its discoverability and rankings in the SERPs. 

Besides this, link-building helps a site drive relevant traffic from different sources. Thus, it is extremely important for SEO.

Popular link-building strategies include guest posting, social bookmarking, business listing, etc.

4. Link Equity/Link Juice

Also known as Link Juice, Link Equity is a search ranking factor based on the idea that links pass reputation or authority from one page to another.

Link Equity is impacted by the linking page authority, topic relevance, HTTP status, and the number of outgoing links.

Higher the number of referring domains on your website, the higher the quality of your site. 

6. Link Acquisition

Having a good link acquisition strategy in place is important to rank high on SERPs.

7. Crawlability 

Every search engine has its crawlers, which scan the web to find new websites and pages and index them in its database. Then, the search engine ranks them for appropriate search queries (keywords).

Crawlability is the ability of a search engine crawler to access and read the content on a site and its pages.

They allow navigation across different pages and make it easy for online visitors to click and explore your website without scrolling up. 

9. Hidden Links 

Hidden Links are links designed to be visible to the search bots only. Users cannot see these links, hence the name.

  • Using white text on white background
  • Covering text with an image
  • Positioning text off-screen using CSS
  • Setting the font size to 0
  • Linking to only one small character like a comma or hyphen

However, using hidden links to manipulate search rankings is a black hat SEO technique. 

It is considered deceptive and spammy, and most search engines penalize websites using hidden links.

23. Deindexed

26. Link Schemes

Link Schemes are an attempt to manipulate a website’s rankings in the SERPs using unnatural links.
