What are some common mistakes marketers make when setting up Google Ads campaigns?

Here are some common mistakes marketers make when setting up Google Ads campaigns, which can lead to wasted budget, poor performance, or missed opportunities:

⚠️ 1. Poor Keyword Targeting

Using only broad match without negative keywords can attract irrelevant traffic.
Not separating branded and non-branded keywords, which makes it hard to track performance accurately.
Not doing proper keyword research, relying on intuition rather than data.

⚠️ 2. Lack of Negative Keywords

Failing to use negative keywords allows your ads to show on irrelevant or low-intent searches.
This leads to low CTRs and poor Quality Scores, driving up costs.

⚠️ 3. No Clear Campaign Structure

Mixing different products/services or audiences into one ad group.
Not segmenting campaigns by theme, funnel stage, or geography.
Makes optimization and tracking very difficult.

⚠️ 4. Weak Ad Copy

Generic or irrelevant headlines/descriptions that don’t match the keyword intent.
Not using responsive search ads effectively.
Ignoring the use of unique selling points or CTAs.

⚠️ 5. Skipping Ad Extensions

Not using sitelinks, callouts, or structured snippets leaves valuable real estate unused.
Reduces CTR and competitiveness in the ad auction.

⚠️ 6. Not Tracking Conversions

No conversion tracking = you’re flying blind.
Marketers often forget to set up or properly configure Google Ads or GA4 conversion goals.

⚠️ 7. Ignoring Match Types

Using broad match only → poor traffic quality.
Using only exact match → missing valuable long-tail traffic.
A balanced strategy is usually better.

⚠️ 8. Improper Location Targeting

Targeting entire countries when only a city or region is relevant.
Forgetting to exclude irrelevant locations.

⚠️ 9. Budget and Bidding Mismanagement

Allocating budget equally across campaigns regardless of ROI.
Using automated bidding without enough data or setting unrealistic targets.

⚠️ 10. Lack of Regular Optimization

Not reviewing search term reports or pausing underperforming keywords.
Leaving campaigns untouched for weeks or months.
Not A/B testing ads or landing pages.

How does BGP prevent routing loops? Explain AS_PATH and loop prevention mechanisms.

In Border Gateway Protocol (BGP), preventing routing loops is critical — especially because BGP is the inter-domain routing protocol used to connect Autonomous Systems (ASes) on the internet. 🔄 How BGP Prevents Routing Loops The main mechanism BGP uses is the AS_PATH attribute . 🔍 What is AS_PATH? AS_PATH is a BGP path attribute that lists the sequence of Autonomous Systems (AS numbers) a route has traversed. Each time a route is advertised across an AS boundary, the local AS number is prepended to the AS_PATH. Example: If AS 65001 → AS 65002 → AS 65003 is the route a prefix has taken, the AS_PATH will look like: makefile AS_PATH: 65003 65002 65001 It’s prepended in reverse order — so the last AS is first . 🚫 Loop Prevention Using AS_PATH ✅ Core Mechanism: BGP routers reject any route advertisement that contains their own AS number in the AS_PATH. 🔁 Why It Works: If a route makes its way back to an AS that’s already in the AS_PATH , that AS kno...

What’s the impact of BGP full routes on router memory and performance?

Receiving full BGP routes (i.e., the full global BGP routing table) has a significant impact on a router's memory and performance. Here's a breakdown of the key impacts: 🔧 1. Memory Usage (RAM) A full BGP table typically contains ~1 million IPv4 routes and growing (~200k+ IPv6 routes). Each BGP route consumes tens to hundreds of bytes of memory, depending on attributes (AS path, communities, etc.). This translates to hundreds of megabytes to several gigabytes of RAM just for storing the BGP RIB (Routing Information Base). The FIB (Forwarding Information Base) , which is installed into the router's hardware or kernel for actual packet forwarding, also consumes memory (especially in TCAM for hardware routers). ❗ Example A router might require 4–8 GB of RAM (or more) to comfortably handle full BGP routes with headroom for growth and stability. 🧠 2. CPU Utilization High CPU load during: Initial BGP session establishment (parsing all rout...

Explain the OSPF LSDB (Link State Database) and how SPF (Shortest Path First) algorithm works.

OSPF (Open Shortest Path First) is a link-state routing protocol , and the LSDB (Link-State Database) and SPF (Shortest Path First) algorithm are core to how OSPF calculates the best paths . Let’s break them down. 🧠 What is the OSPF LSDB (Link-State Database)? The LSDB is a map of the entire OSPF network area — each router stores a complete topology of its area. 🔍 Details: Built from LSAs (Link-State Advertisements) exchanged between routers. Contains info about: Routers and their interfaces Network segments Neighbor relationships Each OSPF router maintains an identical LSDB within the same area. ✅ Key Characteristics: Feature Description Scope One LSDB per OSPF area Source Built from received LSAs Consistency All routers in an area have identical LSDBs Purpose Used as input for SPF algorithm to calculate best paths ⚙️ How the SPF Algorithm Works in OSPF OSPF uses Dijkstra’s Shortest Path First (SPF) algorithm to compute the shortest (lowest-cost)...
