What goes into SEO?

To comprehend the genuine significance of SEO, how about we break the word into parts?

  • Quality of traffic: You can attract in all the guests on the planet, however on the off chance that they’re going to your site since Google reveals to them, you’re an asset for smartphones when you’re a rancher selling Smartphone, that isn’t quality traffic. Rather you need to pull in guests who are inspired by items that you offer.
  • Quantity of traffic: When you have the right crowd navigating from those search engine results pages (SERPs), more traffic is better.
  • Organic results: Advertisements make up a huge bit of numerous SERPs. Natural traffic is any traffic that you don’t need to pay for.

SEO functioning

Think about a search engine as a site you visit to type (or talk) an inquiry on Google, Yahoo!, Bing, or whatever search engine you’re utilizing mysteriously answers with an extensive list of connections to website pages that might address your inquiry.

Be that as it may, have you at any point halted to think about what’s behind those supernatural arrangements of connections?

Here are the means by which it works: Google (or any search engine you’re utilizing) has a crawler that goes out and accumulates data pretty much all the substance they can discover on the Internet. The crawlers take each one of those 1s and 0s back to the search engine to manufacture a list. That file is then taken care of through a calculation that attempts to coordinate such information with your inquiry.

The O stands for “optimization” — where the people who write all that content and put it on their sites are speculating that content and those sites up so search engines will be capable to define what they’re seeing, and the users who arrive via search will like what they see.

Optimization can take many forms. It’s everything from making sure the title tags and meta descriptions are both instructive and the right length to pointing internal links at pages you’re proud of.

SEO working process

Search engines are libraries for the digital age storing web pages. When you type an inquiry into a search engine, it looks through all the pages in its index and tries to hit back with the most appropriate results. To do this, it uses a computer program called an algorithm but nobody knows precisely how these algorithms work.

To give you the most useful data, search algorithms look at many factors, including the keywords, pertinence, and usability of pages, popularity of sources, and your location and settings.

Search engines, for example, Google and Yahoo! frequently update their importance calculation many times each month. At the point when you see changes in your rankings, it is because of an algorithmic move or something different outside of your control. Even though the standard of activity of all search engines is the equivalent, the minor contrasts between their algorithms lead to significant changes in results.

How SEO works?

In simple terms, SEO works by making the search engines believe that your content is the most suitable result for the searched topic. The precise process differs with the search engine you’re optimizing for. If you want more organic traffic your website must cater to Google’s algorithm. For more video views, it’s all about YouTube’s algorithm.

Fun Fact

‘’Google has a market share of ~92%. That’s why it pays to optimize your website for Google instead of Bing, DuckDuckGo, or any other web search engine.’’

How to optimize for Google?

Google ranks web pages, not web sites. This simply means if your business is about “electronics” Google doesn’t want every page on your site with just queries on “electronics”. You can rank for different keywords and topics with different pages.

Now let’s talk about some of the things that affect rankings and search engine visibility.

1. Crawlability:

Before ranking your content, Google ensures that it exists. This is primarily done by is crawling. Crawling is that Google follows links on the pages it already knows about than those they haven’t seen before. To do this, a computer program called spider is put to use.

Let’s say that your homepage has a backlink from a website that’s already in Google’s index. Next time they crawl that site, they’ll follow that link to discover your website’s homepage and likely add it to their index. From there, they’ll crawl the links on your homepage to find other pages on your site.

Some things can block Google’s crawlers:

  • Poor internal linking: Google relies on internal links to crawl all the pages on your site. Web Pages without internal links often won’t get crawled.
  • No followed internal links: Internal links with nofollow tags won’t get crawled by Google.
  • No indexed pages: You can exclude pages from Google’s index using a no index meta tag or HTTP header. If other pages on your site only have internal links from no indexed pages, there’s a chance that Google won’t find them.
  • Blocks in robots.txt: Robots.txt is a text file that tells Google where it can and can’t go on your website. If pages are blocked here, it won’t crawl them.

2. Mobile-friendliness:

More than 50% users come from mobile devices, and that number is growing every year. In 2016, Google announced a ranking boost for mobile-friendly websites in its mobile search results.

Google also shifted to mobile-first indexing in 2018, meaning that they now use the mobile version of your page for indexing and ranking. That’s important because Google wants to keep its users satisfied.

According to Adobe Nearly 8 in 10 of consumers would stop engaging with content that doesn’t display well on their device. Most of the people will likely to hit the back button when a desktop version of a site loads on mobile. Pages that aren’t optimized for mobile lead to dissatisfaction. And even if you do rank and win the click, most people won’t stick around to consume your content.

You can check if your web pages are mobile-friendly with Google’s mobile-friendly testing tool.

2. Page Speed:

Page speed is how quickly your web page loads. If clicking on search results that take too long to load, then it certainly leads to dissatisfaction. To check the speed of your web pages, use “Google’s Pagespeed Insights tool”. Google Page speed works on both desktop and mobile.

4. Search intent:

Finding a keyword that ranks is easy with the help of SEO tools. They find relevant keyword that boost your website.

To demonstrate search intent, let’s look at an example. Here are the current Google search results for the query “best party dress”:

Compare those with the results for the query “party dress”:

Despite the similarity between the keywords, the search results show great differences. So, Google interprets the purpose of the search and brings up results accordingly.

How do you optimize?

Optimizing gets easy with the 3C’s:

  • Content type: What category are most of the results blog posts, product pages, category pages, landing pages, or something else?
  • Format of Your Content: Is Google mainly ranking how-to, list-style articles, tutorials, comparisons, opinion pieces?
  • Unique or Fresh Content: Is there a common theme or unique selling point followed by the top-ranking pages? If so, this gives you some insight into what might be important to searchers.

Beyond this, you can also check for the presence (or not) of SERP features to infer intent.

5. Backlinks:

Google’s ranking algorithm is based on PageRank, in which backlinks are interpreted as votes. So, the greater is the number of votes, higher is the ranking. The problem is that links can be challenging to build, especially to certain types of content like product pages.

There are tons of link building tactics but if you’re new to the game, aim to build links to your best informational content (e.g., a blog post or a free tool). Consider reaching out to these people, explaining why your content is better, and ask if they’d swap out the link for yours. This tactic is commonly known as the Skyscraper Technique.

5. Authority:

Generally speaking, backlinks from high-authority pages are stronger than those from low-authority pages. On 2016, Google discontinued public PageRank score, that means you’ll never check your page authority. There are some famous SEO tools from where you can check domain authority like Ahref, MOZ, and more..

Of course, backlinks aren’t the only way to boost the “authority” of a web page. URL Rating (UR) also takes into account internal links, meaning that links from other pages on your site contribute to the authority of a page. If you want to boost the “authority” of a particular page and are struggling to build backlinks to it, consider adding some relevant internal links from other high-authority pages.

6. Content quality:

Google is precise enough to rank reliable and useful results—always. To do this, they look at content-related signals like expertise, authoritativeness, and trustworthiness. Collectively, these are known as EAT.(Learn more about EAT in Google’s Search Quality Rater Guidelines.)

Other things you can do to increase the perceived quality of your content might be:

  • Stick to a 7th or 8th-grade reading level.
  • Use small Sentences and Paragraphs.
  • Link to useful resources where appropriate.
  • Break your content on images and quotes.

The more accessible your content is to the majority of searchers, the better. Freshness is another important factor for some searches. For example, if you Google “best router,” you’ll see that almost all of the results were published or republished recently.

That happens because technology moves fast. Nobody wants to know what the best routers were in 2016. That wouldn’t be useful. For other queries, freshness is less of a deciding factor.

Take a look at this top-ranking result for “how to tie a tie”:

Nobody has updated the page for over six years, but it doesn’t matter because the way you tie a tie is the same now as it was then. Look at the search results for your target keyword to see whether freshness is seemingly an important ranking factor. Adjust your strategy as appropriate.

Is ranking over-rated?

Google considers factors as location, past search history, and search settings to “tailor your results to what is most useful and relevant for you.” That means if you are seeing your site ranking #1, the same might not be the case for everyone.

For example, if you search for “flapjack recipe” in the UK vs. the US, the results are different.

To check “accurate” rankings, use an incognito tab to offset any personalization from your search history. To offset location factors VPN can be used.

Knowing the working process of search engines and their ranking is crucial while creating top notch content. Moreover, search engine algorithms change constantly and there’s no guarantee that what’s important today will still be important in the upcoming time. But don’t let that panic you because factors like backlinks, “authority,” and page rankings have been critical since the beginning so there’s no sign of that changing any time soon.
