6. How many kinds of SEO Technique? Explain.

There are 3 types of SEO technique as following:

1. White hat SEO:- It is a good practice of SEO. In this technique we follow all terms and condition of Search engine  guidelines. First of all we read the rules and condition of the related website and post content on the specific website. we follow the general rules that is made for all people. we do all activity true as our business, and provide legal information that is related for our services. If we do white hat seo then it is best for our website, it takes some long time but perfect for organic searches. So do more white hat seo for your business website and enjoy your services.

2. Black Hat SEO: It is not a good practice of SEO . it is called unethical seo too. In this technique we do not follow the term and conditions of search engine guidelines and do opposite of rules. As for example, give a link with white text as page color,(hidden text) give a lots of keyword on the site, link with adult site and others sub domain links.  Here are some example of black hat seo ,  keyword stuffing, link farming, Google bombing, hidden text, poor content, link with low page rank website etc.

3. Gray hat seo: it is not bad nor too good for SEO point of view. Because we can say that it is method between white hat seo and black hat seo, Some times we follow the rules and sometime not. it does not harm too much for our website. Some example of gray hat SEO-  purchase paid link, PPC services; these are done only for traffic and business purpose. It does not help in organic searches. Some other gray hat example - Facebook likes and commenting on blog etc.

Domain authority is measured by MozRank, MozTrust, It calculates how much quality link of your website has? What is page page popularity, how much is domain strength over all time from hosted on server. How much quality content on your website? which type of domain you have etc. It is calculated by 0 to 100, You can check your domain authority of your website by this tool:  it is easy to achieve 30 to 50, if you have 30 to 50 DA then your site is good condition. Domain authority between 50 to 80 is excellent and 80 to 100 is super excellent . Facebook and Google page authority is 100/100 .  Now you would understand well.

8. What is keyword stemming ?

SEO point of view keyword stemming is the process of use the main keyword many times to add some prefix and suffix. Suppose the main keyword is SEO services but you can use it best SEO services (prefix) SEO services provider (Suffix) you can make many keywords to add like this word. It is useful to use in article and blog but take care the number of keywords. If you use many times keywords to add this suffix and prefix then it is harmful for SEO point of view. So too much keywords used in website to add like words in main keywords is called keyword stemming and it may be harmful to SEO ranking. But if you use 1 or 2 time in article or blog then it's OK. Now I think you are clear about keywords stemming.

9.What is keyword density ?

Answer -  It is most frequently ask question in SEO Interview. It is generally asked to fresher and expert too. So here I am going to clear properly here-   Keyword Density is percentage of  keywords (phrase) compare to all words that is used in single page (Webpage).  It mean how many times of keywords are used compared to all words in single web page. 

If anybody ask you the calculate the keyword density then simply follow this mathematics formula as told above in definition -    Total Number of Keywords / Total Number of words in Single webpage *100  ( Take an Example - Total Number of Keywords =5, Total Number of Words in Single Web page is = 500 then Keyword Density =  (5/500)*100 = 1%  )   So here called Keywords density is 1%  Now I think you are very cleat about it. 

Keyword Frequency: Keyword frequency is the number of times a particular keyword appears on a website. Common sense may indicate the more times a keyword, or keyword phrase is found on a web page, the better the site will rank in Google.

For example use keyword in title, description, head tag and text but take care of keyword spamming

Keyword Proximity: Keyword proximity refers to how close two or more keywords are to each other. You will achieve higher rankings if you place your keywords close together.

Note - We should keep keyword closer to each other

Keyword Prominence: Keyword prominence refers to how prominent your keywords are within your web page. In simple English, this means how close to the beginning of the web page, sentence, title, h tag, or Meta description your keywords are placed.

10. What is the difference between Search Engine Optimization (SEO) and Search Engine Marketing (SEM)?

Answer -  Yes it is very technical question in interview and it is generally asked if you have more than 1 or 2 years experience in SEO. Many guys are confuse about it and they told sometime that both are same But is not good and interviewer understand that you are not expert; so don't be confuse about it. Let's see the difference -

Now in details -  If you do the activity for website like ON page and Off Page and follow the search engine guidelines and make the website user friendly and search engine friendly so that your website rank in search result on keywords  then it is search engine optimization. For website ranking; we all know that we do many SEO activities like- update meta tag, content optimization, check broken links, URL structure, submit sitemap and so on and promote it by article , blog , press release, classified, business listing and many others. These all are SEO.

Search Engine Marketing - It means do extra activities for business sale and traffic on website directly or indirectly. As for example for business conversion we send direct mail to client, call by phone, Skype or chat online and other major activities that is online advertising called PPC. It means we advertise our business directly on popular search engine like Google, Bing, AOL, Facebook and other sites. These all are come in search engine marketing (SEM).

And may be it will last question for you and you can be selected; if you reply very confidently of this question because all  is includes in this one question.

11. How will you solve Canonical issue or what is .htaccess file?

Answer -  If  website open with more than one URL address like-  etc

Then it is call canonical issues. It is not good for SEO point of view because Google Robots understand these all urls  different web address. It mean Google confuse about your real address of your your website. So we can fix it by two method - By canonical meta or .htaccess file.

Fix Canonical by Meta tag - 


<link rel=”canonical” href=”” />

<link rel=”alternate” href=”” media=”only screen and (max-width: 640px)”>


Note -   Write the URL in canonical which you want to index in Google. in Above example Google robots understand your website only and ignore other urls,---  take care your website still open with all address but you have given instruction of Google robots only one URL. So Google now take care of one url. In this way you can fix the canonical issues.

Very Important -  If you have more than one page then you will have to write canonical meta tag for every page in head tag.  Example -  If your website open more than one url as i said above then you should write canonical tag in about page also like


<link rel=”canonical” href=”” />

<link rel=”alternate” href=”” media=”only screen and (max-width: 640px)”>


Note -  Many CMS platform have setting option to fix canonical issues like -  wordpress, Magento,wix, joomla . So you don't need to write above code in these types of website. Just you have to set your wising URL with www or without www.

If you want to open your website with only one URL then best way to redirect the website with .htaccess file. But remember .htaccess file might differ on the basis of hosting or developed platform. So you should write code carefully. If you don't know properly about .htaccess file then leave it. You should take help by developers in this case.

But Generally we can redirect by the following code 

It is also called 301 (Permanent Redirect)

redirect 301 /old/

How to create .htaccess file and how to use it?

Answer - Just you have to copy the above code in notpad and save it  .htaccess extension (. dot) and upload it on root file on your website. like robots.txt file.

We can also redirect by meta tag (Just below head tag)

<META http-equiv="refresh" content="0;URL=">

Hope you are now clear about  canonical issues if you have any issue comment below.

12. What is the difference between Crawling and Indexing?

Answer -  When we develop a website and make it live online and allow Google Robots to visit site then Google Robots reach our website and read all the code and text which we have written. This process is called crawling and when Google or other search engine Crawl website and keep your website URL and content in their data base then it is called indexing. Google give the result only after index your site. If your url not index in Google search engine then it never show in search result. You can check your website index or not by the following search operator -

If your website is index then it show with tile and description in search result and if your website not index then it show no fund result page.

13. how to fix pagination url through robots.txt

If you have possible duplicate content with your pagination, the idea is not to block pagination URLs with robots.txt but just defining the rel="canonical" tag for your different URLs.

For your four URLs, define this tag in your <head> section:

<link rel="canonical" href=""/>

If you wanted to block just the page's listed, this is what you would need to add to your robots.txt:

Disallow: /category/sub-category/product/1$
Disallow: /category/sub-category/product/2$
Disallow: /category/sub-category/product/3$
