Google is one of the most important companies on the World Wide Web and was initiated as a project led by two students from the Stanford Univerity Ph.D. program, Larry Page and Sergey Brin.
Initially, the students ‘ goal was to create an efficient search engine that provided users with links to their search requests. Today, while this is still Google’s core, the company now provides email, document storage, and other software productivity services.
How Does Google Work?
The Google Search Engine
Google’s search engine is a powerful tool. Finding the information you need would be virtually impossible if you browse the web without search engines like Google.
Like other search engines, Google uses a special search results algorithm. Like most search engines, Google uses automatic programs called spiders or crawlers.
Google has a wide index of keywords and can also find those words, just like other search engines.
What distinguishes Google is how to classify search results Which determines the order Google displays results on its SERP page.
Google uses a marked PageRank algorithm that assigns a pertinence score for each web page.
A Web page’s PageRank depends on a few factors:
- Frequency and location of keywords on the web page: If only once the keyword appears in a page’s body, this keyword will receive a low mark.
- How long this website has been: Every day people build new websites and they don’t all stay there for a while. Google places more value on pages with an established history.
- The number of other websites linked to the page: Google examines the number of websites linked to a specific site to determine its relevance.
Google launched a search engine experiment in 2008. Google allows a group of beta testers to change the search results ranking for the first time. Beta testers can promote or dismantle search results in this experiment and can tailor their search experience more personal.
What Is A Spider?
A spider search engine performs the search engine’s grunt work: it scans web pages and creates keyword indexes. Once a page has been visited, scanned and classified by a spider, links to other websites are followed from that page.
The spider will keep crawling from site to site, making the index of the search engine more robust and complete. Google uses many tools to prevent people from placing themselves fraudulently on SERPs.
For example, a website’s voting power decreases when it adds links to more sites. A high PageRank web page with lots of outgoing links may be less influential than a lower page.
Spiders do not rank web pages in the search engine. They go out and get copies and then send them to a search engine so that they can be added to the search engine database.
The search engines then analyze the information collected by the bots using potent algorithms and place web pages based on their analysis.
How do search engine spider visit websites:
Once a website is in a search engine database, it will be visited regularly by the bots. They check for changes made to it every time they crawl a website. If there are some, the crawlers will make a note and remember to come back a little earlier next time.
Spider search engines can’t see colors, so the colorful spider image below left can’t be appreciated. Actually, it is impossible to see the black and white one with the word “Google” above it. Sadly, you can’t even see the image on the right.
You don’t have to work too hard to crawl and index your new pages. Basically, the spiders will eventually follow the new page and save it for indexation as long as you link from some old content to your new content.
The spider collects HTML meta information from the page upon authorization. Metadata is information that can categorize and organize the site content for search engines.
Above all, links to other pages on your website or other websites will be the main element you can include in your content.
As a result, linking to other websites that are useful for your own content increases the user experience factor.
How Often Do Spiders Visit My WebPage?
The database is different for each search engine, so the frequency of visits varies from search engine to search engine. New web pages are explosive and have slowed the process slightly, but don’t worry. Search spiders are unrelenting mission drones.
You will find your web pages. Spiders will continue to check your pages for changes once you have entered the database and update the database using any new or altered content. Ultimately, most websites rarely matter how many times you’ve visited. You’re not going to change this page you’re reading.
Every website owner should know which sites have been visited by the robots search engine. See your server log reports or the results of your log statistics program. Upgrade your hosting service if you don’t have one. VectorInter with each hosting contract. Net offers these tools free of charge.
Google’s robot is called “Googlebot.” Some are obvious. Others have funny names, the name of the Inktomi robot is “Slurp.” You will learn the names and when you visited your website, which pages are visited and how often you visit them.
Marketers for “spam” are tools for a few unreputable robots. These’ spam spiders ‘ surf the web and indiscriminately record each email address listed on your website. Now you know where your junk email originated in your traffic.
Before I move on, let me give you another practical tip on search engine spiders. Never remove individual web pages from your site without replacing them with the latest updated version. This is a common mistake. If you remove a web page with plans to replace it days later, the spiders will “see” a blank spot and remove it from the database of the library.
You may not be able to update your web pages if your website is down or if your website (a poor web hosting system) is unable to reach your web pages or if your traffic is high (not enough bandwidth at your web hosting company).
Search engines often build their spiders smartly to know that if they can not access an earlier-known website, they should try again later. This is an unnecessary risk to your website. Make sure that you always have access to your web pages.
What Is Google Crawling?
Crawling in the SEO world means following your links and “crawling” your site. If bots come to your website (any page), they will also be followed by other linked pages on your site.
The crawling process begins with a list of web addresses given by website owners from past racks and maps. Our crawlers use links when they visit these sites to find other pages.
New sites, changes to existing sites and dead links are of particular importance to the software. Computer programs identify which websites to crawl, how many pages to catch from each site.
As your search engine passes through our website, the search engine identifies and records all links on these pages and then lists them later. This is how all new content is found.
Search bots wait for previously indexed pages to receive signals such as links to the new content. So when you’ve created and linked a new page from an existing page or menu on your site, it’s a sign for viewing the search bots and you can also introduce indexed new pages to bots through Sitemaps and robots.txt files.
Platforms like WordPress will automatically alert search engines that you have created a new page.
The number of possible URLs generated by server-side software has also made it difficult for web crawlers to retrieve duplicate content. There are never-end combinations of HTTP GET (URL-based) parameters, which in fact only a small selection returns unique content.
For example, in the online photo gallery, as specified in the URL by HTTP GET, there are three options available to users. If there are four ways to sort images, three sizes, two file formats and an option to disable content available to the user.
Indexing is the process of searching for web pages by Google. Google will tear and index your pages accordingly, depending on which metadata you’ve used (index or NO-index). A no-index tag does not include a web page in the web search index.
When a search engine processes each page it craws, it compiles a large index of each word it sees and its location on each page. It’s basically a thousand of thousands of thousands of webpage database.
This index can determine whether a word is present in a specific document because it does not store any information about the word’s frequency and position and therefore considers it to be a boolean index.
After parsing, the indexer adds the referenced document to the document lists for the appropriate words. In a wider search engine, it may take too long to find every word in the inverted index (to indicate that the word was found in the document).
The Google index is like a library index that lists all the books available in the library. The Google index, however, lists all Google’s web pages instead of books. Google detects and updates the Google index when you visit your site.
What Is Google AdWords?
AdWords (Google AdWords) is a Google advertising service for companies that want advertising on Google and its advertising network. The AdWords program allows companies to set a budget for advertising and pay only when people click on the ads.
The ad service focuses largely on keywords. AdWords companies can use keywords to create ads for people searching the web to use the Google search engine. If you are looking for a keyword, your ad will be displayed. AdWords in the top ads below the “Sponsored Links” heading to the right.
You can display ads for users who actively search the keywords you selected with the Google Search Network. When you own a landscape company, every time a user type is present, you try to show your ad in “Landscapers in Tallahassee.”
Types Of Ads In Google Adwords
A. SEARCH ADS:
When a user searches for something on Google, the list of ads above the organic listing is called search ads. For example, when a user searches for “Kashmir holiday packages,” the search results will look like this.
It takes into account many factors before Google decides which ad to display first and the sequence of ads to follow. Afterward, in a more detailed chapter, we will discuss all these factors, their relative importance, the correlation of different factors, etc. But let’s look briefly at them.
Important factors in search ads:
- Targeting: For example, your ads will be shown in the geography you choose (you can go as specific as the zip code)
- Search term and keyword: what the user searches for + the keyword to optimize the ad for.
- The relevance of ad copy: Ads that appear for a specific search term should be relevant. The search for colleges should not result in travel packages.
- Landing page experience: how relevant is the landing page to what the search engineer wanted? Has he got what he was looking for?
- Conversion rate: this is again controlled by relevance, page quality, and experience.
- Bids: If 2 advertisers have perfect ads and landing pages, the higher bid will take preference over the lower one.
- Quality score: Quality score again depends on all the other factors mentioned above, so it’s more like a cycle than everything is interrelated.
B. DISPLAY ADS:
Have you ever noticed them? You can see ads in many different places on the page and in different dimensions while reading or viewing a video on a random website. These are displayed advertisements.
Here, the search engine does not explicitly search what ad offers are. But Google decided to show it to you based on a number of factors such as keywords, public interest, placement management, etc. These ads are only available on advertising-receiving websites.
Below are the targeting criteria that Google selects on the websites for banner ads.
- Keywords: The ads are displayed to optimize them using the keywords. Say’ social media marketing’ is the ad’s keyword, and then Google chooses websites that contain content for this topic.
- Placements: Just add the websites you want to display ads, not the keywords. For example, if you only want to display ads on travel sites, you should view and add ads that are supported by travel sites to your destination. Only advertisements should be shown on travel sites.
- Remarketing: This allows you to reconnect to your website with existing visitors. This allows you to target visitors to your website but who have not taken any action whatsoever.
- Topic: AdWords contain specific topics grouping all websites. Advertisers will find business selection easier – related topics. Travel websites, for example, are listed under the ‘ travel ‘ topic.
C. SHOPPING ADS:
If you were a retailer, this type of campaign would be more meaningful to you. This type of ad increases traffic to your website and helps to generate and increase guidelines for quality.
This is how shopping ads appear on the search network:
D. VIDEO ADS:
This type of ad allows advertisers to run video ads on YouTube and other Google Display networks.
3 main benefits of running a video ad:
- Better targeting: This type of advertisement is tailored to the population, location, interest, keywords, and device to reach the right audience on YouTube and Google’s display network.
- More reach: Since January 2017, YouTube has been the third most visited website with around 30 million visitors every day. You can also access video ads on the Google Display Network. Therefore, you have access to a wider audience.
- Measurable: Unlike on TV, YouTube ads can be used to measure the success of video ads by knowing all the necessary metrics, including views, view speed, clicks, reach and frequency, engagement, performance, etc.
E. UNIVERSAL APP CAMPAIGN:
This is a useful campaign for mobile app companies. Here the advertiser can promote the mobile app PlayStore Display and YouTube throughout your search. AdWords uses ad text ideas and other goods right from your app store listings. You just have to provide a text budget. And from the beginning a bid.
By using this information, AdWords designs a variety of ads in different formats. Google automatically tests various ad combinations and displays the best one.
