Numerous factors can make a website optimized for ranking on a search engine. For on-page optimization, you can make sure that the title tags, meta tags, alt tags, keyword research are done correctly.

6. What are page speed and its role in SEO?

Page speed is how fast your site completely loads for a user. Search engines such as Google rank sites with a fast page speed as more often than not, users bounce back. 

To increase the page speed you can reduce image sizes, compression, improve server time response, reduce the number of redirects, minify the javascript and CSS coding, etc.

7. What is a backlink?

A backlink is a link from an internal or external source that brings the user onto your website. 

8. What is an outbound link?

Outbound links are links that your website gives to another third-party website and directs traffic over there. 

9. What do you mean by keyword density and proximity?

Keyword density is the percentage that tells you how often a search term appears in your content – it is calculated by “ No. of times the search term is used divided by the total number of words in the content multiplied by 100”. 

For example, if a keyword appears 5 times on a page with 100 words, the keyword density would be 5%. If it appears too often, Google can mark it as search engine spam as it may be ingenuine. 

Keyword proximity is the distance between the search term’s individual keywords. If your keywords are placed strategically throughout the content, there is a higher chance of your page getting a better ranking. 

10. What are meta tags? Name the important ones and their character limits.

Meta tags are a snippet of what a web page is about – something like a preview. This text does not appear on the page itself but it appears on Google SERP- it describes what the page is about and helps with search engine rankings. 

There are 2 important types of meta tags –

Meta Title – It is the headline, like a nametag for the page that appears on the search engine page – it is an HTML element. Google recommends a character limit of 70 characters although it is now calculated via pixels and the limit is 580px. 

Meta Description – Meta description is essentially the summary of the article below the meta title. It talks about what the blog is all about. The recommended character limit is 155-160 characters although it is now calculated via pixels and the limit is 990px. 

11. What is a longtail keyword?

A longtail keyword is a phrase that is usually 3-5 words long. Since it is very specific, it helps the brand to target very niche demographics which would attract quality traffic and in turn, lead to conversions. 

For example Nike stores in Mumbai, or best digital marketing courses in Mumbai, etc. 

12. What is a landing page?

A landing page is a web page that a user ‘lands’ on when he clicks on a particular link. The source of this link can be from an email, ad, other website or any other source. 

A landing page is usually created for a particular campaign to track the results. The 2 main goals of a landing page are lead generation and conversion. 

13. What are organic results?

Organic search results are also called natural search results. These are not paid. So, when a user searches for a query on a search engine, the results displayed without the “Ad ” mark are called organic search results. 

If your page ranks organically, or naturally, it means that your on-page and off-page strategy is working well. 

14. What is image alt text?

Alt text also called alt tag or alt descriptions is as the name suggests, a written copy for an image that appears on a webpage and describes what the image represents. 

It is useful for the times when the image cannot load and also rank the images in the “Image” tab on search engines.

15. How to make a URL SEO friendly?

Enhanced URLs are extremely important for both the search engine as well as the user experience. They should be short, easy to remember, to-the-point and well-structured.

Describe your content – the user must be able to tell what your page is about only by looking at the URL. Include your focus keywords in the URL. Include hyphens to separate words as Google recommends this over underscore. Keep URLs brief, well-structured and only use the lower case.  

Avoid using dynamic URLs and stick to static URLs for your site – you can use dynamic URLs for social media to track your data. Use folders that are necessary to your URL and add value. Do not unnecessarily add them in – keep the site structure flat and clean.

They have a penalty for websites that rank high with poor quality content or ingenuine ways that do not serve the end-user. And there was a recent update announced wherein Google can choose to nullify your practices instead of penalising. 

4. What are the doorway pages?

A doorway page is also referred to as a gateway page. It is a web page that is created solely to rank high for particular search queries and they do not offer what the user is looking for.

5. How to remove toxic links from a site?

Toxic links are links from websites that can tarnish your SEO efforts which can lead to fewer organic visitors.

6. What are SERP and DA?

SERPs are Search Engine Result Pages, i.e., the web pages that come up as a result of any search queries. 

DA is domain authority – a search engine ranking metric developed by Moz and many other tools that estimates how likely a website is to rank in a SERP. 

It essentially helps evaluate your website with competitors on a scale of 0 to 100. The higher your score, the higher the likelihood of your page to rank. 

7. What is an XML sitemap and what is its importance?

An XML sitemap acts as a roadmap of your website listing the most important pages so that Google can understand your website structure. The aim is to ensure that the search engine crawls every important page. 

8. Explain rich snippet.

Rich snippets are excerpts or previews of your page. It is additional data that is extracted from your page and displayed before a user clicks on your link. Some common rich snippets include reviews, recipes and events. 

Rich snippets increase the chances of a higher click-through rate as people prefer clicking on the preview that gives them enough data to understand what the webpage is all about.

9. What is a bounce rate?

Bounce rate is the percentage of users that leave a webpage immediately or without taking any kind of action. This can be any kind of action – scrolling through the article, filling a form, clicking on a link or making a purchase.

10. Explain – spiders, crawlers and robots.

Web crawlers have many synonyms – crawlers and robots or bots being a few. These are automated programmes that crawl across the World Wide Web and index all the content on it. 

Once the spider crawls your page, it is put onto Google’s index or simply put, its search engine result page (SERP).

11. Explain LSI keywords

LSI stands for latent semantic indexing keywords. These are related terms or phrases related to a web page’s target keyword. Search engines have become smarter over the years. If a particular keyword density is high, then they would realize it is not an authentic page. 

For example, if your page is about SEO, then your content would include terms and phrases such as bounce rate, keywords, ranking, etc and not only the term ‘SEO’.

LSI keywords help the search engine understand what your content is about and also help your page rank for related keywords. 

12. What does it mean if your domain does not appear in the search?

There can be several reasons if your domain does not show up in the search. 

Some of them are that Google may not have indexed your website yet, your website just went live, the index tags might be missing, your keyword market is very saturated, your website is penalised or you may have unknowingly blocked spider from visiting your website.

Google Analytics gives access to multiple kinds of reports. A few common and popular ones are the Mobile Overview report, audience report, referrals report, channels report, navigations summary, landing pages report, site speed review and goal overview report are some of the important Google Analytics reports.
