List of SEO Terms & Components



According to my continue research on SEO for last 5 years and my own experiments, Today I can say that it is just a technique to know the Search Engines’ algorithms and present our content in a proper way so that search engines can easily find our content and can crawl/index our content. But since SEO has become more complex in the recent years, therefore, newbies get confused all the time when they enter to the filed of SEO. But the basic SEO fundamentals are the same as it could be a few years back. In this article, I’ll tell you some of the important SEO terms and components which you’ll see overtime after diving into the SEO world. There is an explanation to each term below.

SEO tips & tricks

1. What is SEO?

SEO stands for Search Engine Optimization and it was initially used in 1990s for finding better webpages by Search Engines, but after Google’s invention, it opened the eyes of webmasters. Today, it is in its advance shape.

2. On-Page SEO

On-page SEO simply means, the work you do within your website for SEO is called On-page i.e website design, navigation, Pagelayout, interlinking, titles, meta tags, headings etc.

3. Off-Page SEO

Off-Page SEO simply means, the work you do outside your website for SEO is called off-page i.e submitting site to search engines, sitemaps, backlinks, social bookmarking etc.

4. Title Tags

The title tag is the most important SEO component which is used for giving a title to a webpage. It is simply an HTML tag.

5. Meta Tags

Meta tags are special/reserved HTML tags that are used to describe the content of a webpage. These tags are commonly used in SEO terms. Usually, meta tags are: Description, Keywords, Author, Robots, Generator. And they are used in the head section of a webpage.

6. Headings

Headings are also important components of SEO, a webpage may be having many paragraphs, so for each paragraph we can use different headings. Always sorting for Headings is as follow: H1, H2, H3, H4, H5, H6.

7. Keywords

The special/reserved words that describe the whole page is called keyword or keywords. They are mostly included in the title tag and used again and again in the entire page.

8. Keyword Density

The limit of a keywords in a complete article is called Keyword density. The maximum keyword density is 3% percent for the whole page. So if you write an article of 500 words the keyword may be included 15 times but not more than that.

9. Keyword Stuffing & Cloaking

This is a black hat SEO technique which is no longer accepted by Search Engines. This technique is used to cheat search engine crawlers; by using this technique some webmasters include a huge number of keywords in meta tags or in the page. Also they use different techniques to deceive visitors as well as search engines i.e hiding the original text from the user or positioning it somewhere, where it can’t be seen by human eyes.

10. Robots, Spiders & Crawlers

These are search engines software/system/algorithms which discover new webpages on the web and index them in their servers. These three names give the same meaning.

11. Internal Links

Interlinking is a technique which is used to create links within a website with particular pages.

12. External Links

This is a technique that is used to insert external links in a webpage, these links are indicating to other websites. If the links are not kept Nofollow then they are crawled by search engine robots.

13. Inbound links

Inbound links are those links that are outside your website on the web, but linking back to you. It is an indication for search engines that your site has been also somewhere else.

14. Outbound Links

Outbound links are those links that are going outside from your website. If they are not kept Nofollow they can be crawled by Search Engines crawlers.

15. Backlinks

Backlinks are those links which are outside your website but indicating back to your website. Those links with Dofollow attribution are called Backlinks. The other are just outbound links.

16. Nofollow

It is an attribute that tells the search engine crawler not to follow a particular page or link. So if a website dosn’t want to index a webpage or link, simply a nofollow attribute is added.

17. Dofollow

Dofollow is an attribute that tells the search engine crawler to follow the webpage or link entirely. By default all links are dofollow if they are not changed.

18. No Index

No Index is another attribute that instructs the crawler to not index the webpage. The link can be followed but the content won’t be indexed.

19. Sitemaps

Sitemaps are the best way to tell the search engines about your site’s complete A to Z content. It is essential for driving massive traffic from search engines.

20. Robot.TXT

This is simply a text file that is kept in the root directory of a website, it instructs the search engine crawler about the restricted webpages or directories which shouldn’t be accessed by them.

21. Google Panda 

A Google search algorithm which is created for detecting low quality pages and websites with copied content.

22. Google Penguin

A google search algorithm that is designed to detect websites with spammy links, over-optimization, keyword stuffing and unnatural links.

23. C Class IP

This is something strange, but worth knowing, every website is given a unique IP address, so if you have a single hosting account and have multiple sites hosted on that, then the C Class maybe the same and the C class is the third number of the IP for example; 22.33.44.55, so the 44 is C class, if this is the same for multiple websites then if one website was penalized by Google, the other websites on the same IP may also be caught.

24. Domain Authority (DA)

This is a ranking based on the age of the domain, the backlinks to the domain and the overall ranking of the domain. So domain authority ranking may be vary for every website, above 30 DA ranking is considered good and above 50 is the best.

25. Page Authority (PA)

This is something very interesting, the page authority or PA ranking is different for each web page on the web, but mostly people try to know about their Home page PA.

26. Link Popularity

This is another term which is used for knowing the link popularity of any web page, people however, are only happy with home page link popularity, but you can check every page’s link popularity.

27. Page Rank (PR)

Page Rank is given by Google to every website/blog on the internet, and it is based on the total number of links/backlinks a website has. This is a numeric ranking starts from 0 and the highest value is 10. So your site can get any PR from 0 out of 10.

28. Alexa Traffic Rank (ATR)

This is not directly related to SEO, but considered to be in touch with SEO, so it is a traffic ranking system, Alexa gives traffic rank to each website on the web.

29. Author Rank (AR)

This is a new term introduced by Google recently, this will be involving in SEO because if the author (Web master) of the website is having good ranking then his website will be given more exposure by Google.
