What is Social Bookmarking?

In the world of digital marketing, Social Bookmarking has become the new norm. The internet plays home to tons of social bookmarking sites. This has come as a boon for ambitious businesses as they can use them for effective organic growth.

So how do websites actually use social bookmarking in their favor? Firstly, all they have to do is bookmark their web pages on top dofollow bookmarking sites for revisiting later. The process creates a good network of backlinks that helps a page’s performance. This is especially true if you use a high DA social bookmarking sites list. Choosing your bookmarking sites effectively will increase your SERP rankings as well as domain authority.

SQL Interview Questions Every Fresher Should Be Prepared

#2 | Friday, July 4, 2025, 06:30:00 | Comments: 0
SQL interview questions assess a candidate’s understanding of database concepts, query writing, and problem-solving with relational data.

In today’s competitive job market, freshly graduated developers and data professionals often stumble on seemingly basic SQL questions during technical interviews. Despite extensive coursework, many falter due to gaps in practical knowledge, unfamiliarity with dialect differences, or inability to reason through edge cases. This article explores the key reasons for failure and offers concrete strategies—including essential SQL interview questions—to help you stand out.


Why Freshers Struggle

  1. Theory vs. Practical Usage
    Academic exposure often covers syntax, but candidates rarely practice writing real-world queries. For example, a typical SQL interview question might ask: “What is the difference between UNION and UNION ALL?”—a question that trips up many because understanding performance implications matters.
  2. CRUD Confusion
    Basic commands—SELECT, INSERT, UPDATE, DELETE—are familiar, but nuanced behaviors like when to use TRUNCATE vs. DELETE, or how transactions affect data integrity, frequently stump juniors .
  3. Challenge with Joins and NULLs
    Joins are foundational, yet many falter when asked, “Explain different types of joins with examples”, or when NULL-handling in NOT IN queries leads to unexpected empty result sets.
  4. Neglecting Indexing and Normalization
    Understanding what indexes are and how normalization impacts design and performance is often overlooked—though these are common SQL interview questions even for freshers.

How to Turn It Around

  • Focus on real queries: Practice full-stack exercises—joins, subqueries, indexing, grouping.
  • Study pitfalls: Know scenarios like NULL causing logical traps in NOT IN, and performance trade-offs between UNION and UNION ALL.
  • Draw schema diagrams: Normalize, define keys, and plan indexing strategies.
  • Explain your reasoning: Employers value clear explanations of why, not just how.

Social Bookmarking websites are growing in popularity for several reasons, they are not only a great personal tool but also an increasingly powerful tool for business. But why you should use social bookmarking for SEO? The idea behind social bookmarking is that people “bookmark” something that they have seen on the internet to publicly accessible social websites, other people can then see your social bookmark, read what you have bookmarked and then share it again. This creates a much larger level of exposure for the content
