30 Most Important Google Ranking Factors for SEO
Updated: Nov 9
As you all Know Google uses about 200 various factors to rank a site.
Apparently, It doesn’t matter how accurate this number is. The sheer magnitude of it is still intimidating. Especially for someone only starting to rank their site.
But here is the catch. Not all those factors are equally important. Some are indeed a must haves but others might not make much of a difference on site & it ranking on SERP.
If you just launched your site and try to find out what aspects of SEO you should focus on first, here’s a treat for you. A list of the most important Google ranking factors which you should know & work on.
The way your page is optimized has the most profound effect on its rankings. Here are the page optimization factors that can affect its search visibility:
Keyword in the title tag - The title meta tag is one of the strongest relevancy signals for a search engine. The tag itself is meant to give an accurate description of the content of the pages. Search engines use it to display the main title of a search result. Including a keyword in it will indicate to search engine what to rank the page for. Ideally, the keyword should be placed at the start of the title tag. Pages optimized this way will rank better than those with keyword closer to the title’s tag end.
Keyword in meta description tag - The importance of the meta description tag today is often discussed in SEO circles. It is nonetheless still a relevancy signal. It is also crucial for gaining user clicks from search results pages. Including the keyword in it makes it more relevant to a search engine and a searcher.
Keyword in the H1 tag - H1 tag is yet another relevance factor, serving as a description of the content of the pages. In spite of an ongoing discussion about its importance, it is still a good practice to include your keyword in a unique H1 tag on a page.
Using keywords in the page's copy - Up until recently, stuffing your page with keywords was a surefire way to increase its rankings for a particular keyword. That’s not the case anymore. Using the keyword in the copy still sends a relevancy signal of what the content is about. How you place it, however, has changed drastically.
The length of the content - These days searchers want to be educated and won’t satisfy with basic information. Google, therefore, looks for authoritative and informative content to rank first. And it’s common sense that the longer your content is, the greater the chance that you can cover more aspects of your topic. Don’t be shy of writing long but highly useful copy then.
Duplicate content - Not all factors can influence your rankings in a positive way. Having similar content across various pages of your site can actually hurt your rankings. Avoid duplicating content and write original copy for each page.
Canonical tag - Sometimes, however, having two URLs with similar content is unavoidable. One of the ways from preventing this from becoming a duplicate content issue is by using a canonical tag on your site. This tag does one simple thing; it tells Google that one URL is equivalent of another, clearly stating that in spite of two pages having the same content, they are in fact one.
Image Optimization - It’s not only text that can be optimized on a page but other media too. Images, for instance, can send the search engine relevancy signals through their alt text, caption, and description for example.
Content Updates - Google algorithm prefers freshly updated content. It does not mean that you have to edit your pages all the time. I believe that for commercial pages, such as product descriptions Google recognizes the fact that they are not as time-sensitive as blog posts covering recent events. It is wise however to include some strategy to update certain types of content once every 12 months or so.
Outbound links - Linking to authoritative pages sends trust signals to the search engine. Think of it this way, the only reason why you would send a user to another site is if you wanted them to learn more of the subject. This can be a huge trust factor for Google. Too many outbound links, however, can significantly diminish the page’s PageRank, hurting its search visibility. Outbound links can affect your rankings but use them in moderation.
Internal links - Interlinking pages on your site can pass their strength between them.
Keyword in URL - Including the keyword in the URL slug (that’s the bit that appears after the “.com/“part of the URL) is said to send another relevancy signal to Google.
There are certain site-wide factors that can affect your site’s search visibility as well:
Sitemap - A sitemap helps search engine to index all pages on your site. It is the simplest and most efficient way to tell Google what pages your website includes.
Domain trust - Trust matters. It’s hard no to think that sites Google trusts should rank higher. But how do you build that trust? Brian from Backlinko has a full list of trust factors here. Needless to say, building trust factors of your domain will certainly pay off.
Server location - Some SEOs believe that a server’s location helps to boost rankings for that particular country or region.
Mobile optimized site - Only a year ago, 46% of searchers used mobile exclusively to research. I believe this number increased exponentially in the last 12 months. It would be no surprise then that having a mobile-optimized site would affect rankings in some way.
When ranking your pages, Google looks at factors outside of your site as well. Here are some of the key ones:
The number of linking domains - The number of domains linking to you is one of the most important ranking factors.
The number of linking pages - There might be some links from a particular domain to your site; their number is a ranking factor too. However, it is still better to have more links from individual domains rather than from a single domain.
Domain Authority of linking page - Not all pages are equal. Links to pages with higher domain authority will be a bigger factor than those on low authority domains. Therefore, you should strive to build links from high domain authority websites.
Link relevancy - Some SEOs believe that links from pages related to the topic of your page carry more relevancy for search engines.
Authority of linking domain -The authority of a domain may be a ranking factor too. For that reason, a link from low authority page on a high authority site will be worth more than from a lower domain authority one.
Links from a homepage - Similarly, some SEOs believe that links from a home page of a linking domain carry more strength than those on one of its pages.
A number of do-follow vs. no-follow links - Google officially stated that they don’t count no-follow links (link with rel=nofollow attribute attached). Therefore the number of your do follow links should affect your rankings too.
The diversity of link types -The types of links you build to your site matter too. Too many links of one type may be a spam indicator and impact your rankings negatively.
Contextual links - It is said that links within the content of the page are worth more than links in a sidebar for instance.
Link anchor - Anchor text of a link used to be a strong ranking factor. Today it can be utilized as a web spam indicator, negatively impacting your rankings.
Lastly, your domain can affect your rankings as well. Some of the domain signals aren’t as strong as they used to be, there are few things worth paying attention to:
Domain registration length - Google considers domains registered for longer than a year as more trustworthy. QUOTE.
Domain history - You may not be the first person who registered the domain. And if your domain has been penalized in the past, its history might affect its current rankings.
Country TLD extension - If you try to target a particular local market, it is said that having a domain with a country-specific TLD (.pl, .co.uk or .ie for instance) will help to achieve better rankings for that location.
