These are the main SEO RANKING FACTORS of 2018 as per google rules and regulations.

1. WHAT IS SEO RANKING?
Rankings in SEO refers to a website's position in the search
engine results page. There are various ranking factors that
influence whether a website appears higher on the SERP
based on the content relevance to the search term, or the
quality of backlinks pointing to the page.

4. THE MAIN FACTORS ARE:

5. KEYWORDS
 Usage of keywords in domain: Having keywords in the domain is a
relevant signal where the keywords appearing in the content, albeit well
incorporated, positively affect the search results.

Use keywords at first word of Domain: Get the extra edge over others
by starting the domain name with the targeted keyword! This is a crucial
and an indisputable keyword ranking factor that can boost your site’s
ranking on the search engines.

Keyword in Sub-domain: One of the important keyword ranking
factors is to include keywords in the sub-domain. moz’s 2011 panel
agrees that this fact can actually help boost rankings.

Keywords in title: Keeping the keywords in the title is a smart move, if
you are looking to increase your seo ranking. This can be a strong On
Page SEO signal to boost page ranking.

: Using the keywords in URL is useful and is one of the most important
relevancy signals.

6.  Keywords in Description:Using keywords in descriptions is
quite relevant and does make a difference, although it
isn’t hugely important.
 Keyword in H1 Tag: H1 tags are the “second title tag” of Google
and by incorporating the right keyword in the H1 Tag, the Google
SEO rankings get a boost.
 LSI Keywords in Content: LSI (Latent Semantic Indexing)
keywords in content extract meaning from words with more than
one meaning. This enables writers to comeup with quality
content. LSI keywords help web spiders to understand the topic
better.

LSI Keywords in Title and Meta Description: Using keywords
in meta descriptions and title helps Google discern between
synonyms and this in turn increases SEO rankings.

Keywords in H2 and H3 Tags: Making the keyword appear in
the subheadings, in H2 or H3 format, is another relevant factor
for SEO rankings.

Keyword Usage in URL: Using the keywords in URL is useful
and is one of the most important relevancy signals.

8. DESCRIPTION
 Description: Fill description focusing on your main
keyword.

longtail keywords: Includes your main 4
keywords of your description

Search Description: Add unique search
dsecription by applying and focusing on post main
focused keyword

9. PERMALINK
 Permalink: Add permalink by focusing on your
main keyword of your post

10. LOCATION
 Targeted Location: Targeting the location is very
important in order to attract the particular area
audiance.

11. IMAGE OPTIMISATION
 Image optimisation: Image optimisation is very
necessary in order to attract the audience.

13. BACKLINKS
 Backlinks: Backlinks remain an important Google ranking
factor, but over the years, Google has learned to weed out the
bad links from the good. More links will still result in a higher
score, but only if they’re from a number of diverse and
authoritative domains.
 The key to a strong link building campaign is to create content
people crave, and then to promote that content relentlessly.
When other industry authorities read and link to your content,
Google will read your backlink’s matching anchor text and
consider your content more relevant.
When your content earns a lot of these high-quality backlinks,
you hit three important ranking signals: number of backlinks,
link authority, and link diversity.
Note that one of the main roles of social signals is to win you
more high-quality backlinks. SearchMetrics found that ranking
position and social signals strongly correlated across all social
media channels — though Facebook is still the platform with
the highest concentration of user interactions.

14. HOW TO OPTIMISE
 There are many different ways to approach link building, but
what they all boil down to is content marketing. Step one:
Create high-quality content. Step two: Promote.
If you’re not sure where to start, I recommend reading this
article by Anna Crowe on important link building statergies. If
you’re having trouble coming up with original content,
consider using the Skyscraper link building technique: Find
someone else’s relevant content with lots of backlinks,
improve upon their content with a more detailed article, and
then share your content.
I also recommend you use link auditing software to get a
better picture of your link profile. Use this software to:
Monitor how many links your content has and the quality of
those links.
 Reach out to high-quality partners for backlinks.
 Eliminate spammy and low-quality links; disavow them if you
can’t get them removed.

15. CONCLUSION
SEO is an ever-evolving industry. In the past few years, we’ve seen
Google make a steady push for rich content, quality links, and a perfect
mobile experience. Other ranking factors are certainly important and will
play a role in your rankings, but if you prioritize improving elements of
your website related to these factors, then you’ll come out ahead of the
competition.
