What is Keyword stuffing in SEO?


Keyword stuffing is considered to be an unethical search engine optimization (SEO) method. Keyword stuffing happens when a web page is loaded with keywords in the Meta tags or in content. The replication of words in Meta tags may explain why many search engines no longer use these tags.

Keyword stuffing can be known to be either a white hat or a black hat tactic, conditional on the context of the technique, and the opinion of the person judging it. While a great deal of keyword stuffing is employed to help in spamdexing, which is of little gain to the user, keyword stuffing in certain circumstances is designed to help the user and not skew results in a deceptive manner. Whether the term carries a pejorative or neutral connotation is in need of whether the practice is used to pollute the results with pages of little relevance, or to direct traffic to a page of importance that would have otherwise been de-emphasized due to the search engine's inability to interpret and recognize related ideas.

A short note on Railways

Rail transport is the transport of passengers and supplies by means of wheeled vehicles mainly designed to run down railways.

A railway/railroad track includes of two parallel iron rails, generally anchored vertical to beams, termed sleepers or ties, concrete, or steel to keep a steady space apart, or gauge. The rails and perpendicular beams are normally then placed on a base made of concrete or condensed earth and gravel in a bed of weight to stop the track from buckling as the ground settles over time below and under the weight of the vehicles passing above. The vehicles traveling on the rails are placed in a train; a string of individual powered or unpowered vehicles joined together, displaying markers.

A short on Music

Music is an art structure that has organized sounds and silence. It is communicated in terms of and the value of sound.

Music may also engage generative forms in time through the creation of patterns and combinations of standard stimulus sound. Music possibly will be used for artistic, expansive, entertainment, traditional purposes.

In the Romantic era, music became more communicative and touching, increasing to include literature, and philosophy. Later on Romantic composers created multifaceted and frequently much longer musical works. The 20th Century saw a revolution in music listening as the broadcasting gained fame worldwide and new media and technologies were developed to record, capture, and replicate and distribute music. The 20th Century music brought a new liberty and broad testing with new musical styles and forms that challenged the accepted rules of music of previous periods.

How do Lenses and frames made?

The Lenses are characteristically made from one of three materials. They comprise glass, plastic (usually acrylic), and polycarbonate. Glass lenses have the finest optical clearness and scratch resistance, but are heavier than plastic or the polycarbonate lenses. They can also shatter or break on impact. The Plastic lenses are lighter than glass lenses, but are more prone to scratching. They do on the other hand, offer more resistance to shattering than glass. The Polycarbonate lenses are even lighter than plastic lenses. They are shatter-resistant (but not indestructible) making them apt for impact protection.

The Frames are normally made from plastic, nylon, a metal or metal alloy. Nylon frames are generally used in sports for the reason that they are light weight and flexible. They are able to twist slightly rather than breaking when pressure is applied to them. This flex can also help out the glasses grip well on the wearer's face. Metal frames are generally more inflexible than nylon frames thus they can be more simply damaged when participating in sporty activities, but this is not to say that they cannot be used for such activities. For the reason that metal frames are more rigid, various models have spring loaded hinges to help them grip the wearer's face better. The end of the ear pieces and the bridge over the nose can be textured or have a rubber or plastic material to hold better. The ends of the ear pieces are generally bent so that they wrap around the ear; on the other hand, some models have straight ear pieces. Oakley, for instance, has straight ear pieces on all their glasses.
