Basic SEO Interview Question for Fresher

SEO stands for Search Engine Optimization. It is the practice of optimizing a website to increase its visibility for relevant searches. The better visibility a site has in search results, the more likely it is to attract attention and drive traffic to the site

The main components of SEO are On-page SEO, Off-page SEO, and Technical SEO. On-page SEO involves optimizing individual pages to rank higher and earn more relevant traffic. Off-page SEO involves activities outside the website like link building. Technical SEO focuses on improving the site’s backend structure and foundation.

A keyword is a specific word or phrase that users enter into search engines to find information. Keywords are important in SEO because they help search engines understand the content of a webpage and match it with relevant search queries.

A backlink is a link from one website to another. Backlinks are important in SEO because they are considered by search engines as votes of confidence, which can improve a site’s ranking and authority.

White hat SEO refers to ethical optimization techniques and strategies that follow search engine guidelines. Black hat SEO involves using deceptive or manipulative tactics to achieve higher rankings, which can result in penalties from search engines.

Meta tags are snippets of text that describe a page’s content. They don’t appear on the page itself but only in the page’s code. Common meta tags include the title tag, meta description, and meta keywords tag.

A sitemap is a file where you provide information about the pages, videos, and other files on your site, and the relationships between them. Search engines like Google read this file to crawl your site more effectively.

Keyword research involves finding and analyzing search terms that people enter into search engines. The process includes identifying potential keywords, assessing their competitiveness and search volume, and selecting the most relevant and effective keywords for your content.

 A robots.txt file tells search engine crawlers which pages or files the crawler can or can’t request from your site. This is used mainly to avoid overloading your site with requests and to prevent certain pages from appearing in search engine results.

Common on-page SEO techniques include optimizing title tags, meta descriptions, headers, and content with relevant keywords, using internal linking, ensuring mobile-friendliness, and improving page load speed.

 Page speed is important in SEO because search engines consider it as a ranking factor. Faster-loading pages provide a better user experience and can reduce bounce rates, which can positively impact a site’s ranking.

Alt text is used to describe the content of an image. It helps search engines understand what the image is about, which can contribute to better SEO. It also improves accessibility for users with visual impairments who use screen readers.

Organic search results are the listings on a search engine results page (SERP) that appear because of their relevance to the search terms, as opposed to being advertisements. Paid search results are advertisements that appear on top of or beside the organic results and are marked as ads.

An XML sitemap is a file that lists a website’s essential pages to ensure search engines can find and crawl them all. An HTML sitemap is a page on your website that helps visitors find content and navigate your site. XML sitemaps are primarily for search engines, while HTML sitemaps are for users.

A canonical tag is a way of telling search engines that a specific URL represents the master copy of a page. Using the canonical tag prevents problems caused by identical or duplicate content appearing on multiple URLs.

Technical SEO Interview Question

Technical SEO refers to the optimization of a website’s technical aspects to improve its visibility and ranking in search engine results pages (SERPs). This involves ensuring that a website is properly crawled and indexed by search engines, has a fast loading speed, is mobile-friendly, has a secure HTTPS connection, and uses structured data for rich results.

 

Making a website mobile-friendly involves using responsive web design, which adjusts the layout based on the screen size and orientation of the device. This can be achieved by:

  • Using flexible grids and layouts.
  • Optimizing images for different devices.
  • Implementing a viewport meta tag to control layout on mobile browsers.
  • Ensuring touch-friendly navigation.
  • Reducing page load times with optimized images and minimized code.

Page speed is crucial for SEO as it directly affects user experience. Faster loading pages lead to lower bounce rates, higher user engagement, and better rankings in SERPs. Google has indicated that site speed is a ranking factor, and tools like Google’s PageSpeed Insights can help identify areas for improvement.

 

Improving a website’s crawlability can be done by:

  • Creating and submitting a comprehensive XML sitemap.
  • Using robots.txt to control which pages search engines should crawl.
  • Ensuring internal linking is logical and helps with site navigation.
  • Fixing broken links and redirects.
    Minimizing duplicate content to avoid confusing search engines.

Canonical tags are HTML elements used to prevent duplicate content issues by specifying the “canonical” or preferred version of a webpage. This helps search engines understand which URL to index and rank, ensuring that link equity is not split between multiple versions of the same content.

 

HTTPS (Hypertext Transfer Protocol Secure) is important for SEO because it provides a secure connection by encrypting data between the user and the server. Google considers HTTPS a ranking signal, and websites using HTTPS are favored over non-secure ones. It also builds trust with users, enhancing their overall experience.

 

Structured data is a standardized format for providing information about a page and classifying the content. Schema markup is a type of structured data that helps search engines understand the content of your website. By using schema markup, you can enhance your search listings with rich snippets, such as review stars, event details, and other information that improves click-through rates.

 

Duplicate content can be handled by:

  • Using canonical tags to indicate the preferred version of a page.
  • Setting up 301 redirects to point duplicate content to the original page.
  • Using the “noindex” meta tag on pages that should not be indexed.
  • Creating unique, high-quality content to avoid duplication.
  • Consolidating similar content into a single comprehensive page.

Common tools for technical SEO audits include:

  • Google Search Console for monitoring and troubleshooting site performance.
  • Google Analytics for traffic and behavior analysis.
  • Screaming Frog SEO Spider for crawling websites and identifying technical issues.
  • SEMrush and Ahrefs for comprehensive
  • SEO analysis and tracking.
  • PageSpeed Insights and GTmetrix for page speed optimization.
  • Moz Pro for on-page optimization and link analysis.

To fix a website with slow load times, you can:

  • Optimize images by compressing them and using appropriate formats.
  • Minimize CSS, JavaScript, and HTML files to reduce their size.
  • Implement lazy loading for images and videos.
  • Enable browser caching to reduce server load.
  • Use a Content Delivery Network (CDN) to distribute content efficiently.
  • Optimize server response times by upgrading hosting services or using faster servers.
  • Ensure that third-party scripts and plugins are minimized and optimized
