According to my continue research on SEO for last 2 years and my own testing, I can say that it is just a technique to know the Search Engines’ bots algorithms and criteria properly. There aren’t anything hidden in this. Search engines like Google itself has stated many times the best practices of SEO on their help pages. One can visit Google’s own sites and within 10 minutes can clear his/her concept about SEO.

I’m myself researching and learning SEO since 2010, and I found a countless number of tips on the internet, however, my own implementation worked well and that’s my experience.

From my prospective, SEO or Search Engine Optimization is a technique/process that is used to convince the Search Engine’s Spiders to index and rank your online content. As Search engines crawlers are just software not human, but to know about them you can read their coding/formulas. Now here I want to let you know about the 30 basic aspects of SEO. So make sure you remember them and use them in the future for explaining SEO to someone.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

These were some basic SEO components and you must learn them in order to optimize your own blog or website by yourself. Comments and questions are welcomed and sharing this post is also appreciated.
