Content quality

The most important ranking factor was, is and will be the quality of the content. The first and most important SEO rule is to create high quality and useful content for a specific target audience.
But what qualifies as high quality content for search engines?

Here are some of the things your content should have in order for it to be classified as high quality. Should:

Be unique and original
Give value to readers
Be fresh and up to date
Cover the topic in detail
Be well structured and scannable
Be optimized for the right keywords


This is probably one of the most important factors of search engine ranking, because without backlinks you will not get too much organic traffic.
Backlinks help Google find and index your website. The quality of your backlinks shows how authoritative and trustworthy your website is.

If other authorized websites link to you, then in Google books, your website is also a good one. If two websites have similar content, but one has better backlinks, then Google will rank so much in search results.

Suffice it to say that backlinks improve your site’s chances of ranking higher and should be a major area of ​​your SEO efforts.

But how do you know if your site has a good backlink profile or not?

Use SEO tools to analyze your website and find out how good (or bad) your current backlink profile is and how you can improve it.

The answer on mobile

These days, a significant portion of online traffic comes from mobile devices. So, if a website does not play well on mobile devices, it not only loses valuable traffic, but also sends bad signals to search engines.
After all, Google doesn’t kindly look at websites that users return to without reading the content. So, optimize your website for mobile devices and make sure it looks good on all screen sizes.

Mobile compliance is also important because of Google’s approach to the first mobile device. If you have a regular site and a mobile site, Google will use the mobile site for crawling and indexing.

The best thing to do is not have two versions of the website at all and create a single web website that can be viewed on all devices. To do this, use good website building platforms that offer mobile-friendly templates and designs for all types of websites. Tip: SEO professionals are not in Olx!


We all know how important keywords are for SEO. However, now you also need to check your keyword search intent and make sure that your content matches it.
What is the intention in the search?

When a user types in a search query, they either want information, are looking to buy something, or are trying to find a location or store. The reason someone types a specific search query is the search intent.

Sometimes similar keywords may have different search intentions. For example, if someone is looking for “the best sports shoes”, they could simply do some research before buying the product. In this case, the search intent is educational, and your content should ideally inform the user about the best sports shoe brands on the market.

However, if a user types “buy sports shoes online”, he intends to buy and search for retail websites that sell sports shoes. So, if you are a retailer, you should opt for this keyword over the previous one.


RankBrain is Google’s algorithm for measuring user experience on a site and is one of the most important ranking factors.
Google strives to direct its users to the most useful and easy-to-use websites. So if your site does not send good UX signals, it will not receive rankings on the first page.

Google analyzes values ​​such as bounce rate, clickthrough rate, residence time, etc.

So how can you improve the user experience of your website?

Here are some tips to get you started:

Keep the look and feel of your website as simple as possible.
Create scannable content and avoid long text content.
Use internal links to drive traffic to other pages on your site.
Optimize your meta titles, descriptions, and URLs to get more clicks.
These are just a few of the many SEO techniques you can follow to improve the user experience of your site.

  1. Keywords
    Any list of search engine ranking factors is incomplete without mentioning keywords.

Every content you post on your website should be created with a target keyword in mind. And you need to add that keyword to that content long enough for Google to recognize what your content is about.

So what should be the ideal keyword density?

Although there is no strict rule, a keyword density of 1% -2% is good enough for most content types. However, for landing pages, you can maintain a slightly higher density.

There are many SEO improvement tools that you can use to check and optimize your content and keyword density.


The most important search engine ranking factors change from year to year, but some (such as content quality) remain constant forever. This post aims to provide a quick reference for anyone looking for the most relevant and important ranking factors for 2021.

Focus your SEO efforts on these and move on to other aspects only after you have optimized for all six ranking factors.
