7 Off Page SEO Techniques to boost search ranking

Off Page Search Engine Optimization includes activities that need to be performed apart from creating your web site. In this post I’ll cover the top 7 off-page optimization techniques that you can utilize to maximize your website search engine ranking. It is ordered below according to their priority.

Off Page SEO Techniques

Off Page SEO Techniques

1. Link Quality and Quantity

Majority of the factors which affect search engine ranking is related to quantity and quality of backlinks you get from other web sites.  More than quantity, it the quality of the web site (Who refers to your web page) plays significant role in search engine ranking.

2. Localize

Make your website local so that search engines can easily view your website and fetch its content. This will help you to reach a targeted audience. Submit your website to Google Local, Maps, Yahoo Local, Yellow Pages, Superpages, Hotfrog, etc.

3. Link Anchor Text

Anchor text or link text used to refer to your page is important for higher ranking. Using keywords in anchor text signals Google that linking sites thinks that content in your site is relevant to the keyword used in link anchor text.

4. Social Presence

Create account with Facebook, Google+, Twitter, LinkedIn, PInterest. The number of +1s you get in Google posting increases your ranking significantly. Merge your Google+ page with Google local business page. Verifying your business page with your web site gives boost for your ranking.

5. Social Shares

Social bookmark your pages in popular bookmarking sites like Pinterest, Digg, Delicious, StumbleUpon, etc.

Share your website documents like business documents, information brochures, and slides in Google Docs, Slide Share, etc. This will help you brand your website. Ask your friends to share or like your documents in social media websites to increase popularity.

6. How-to Videos

Create YouTube channel and upload How-to videos which demonstrates your product. YouTube can sometimes be used as backdoor to get into first page of Google search results for new sites. Add video gallery page to your website and embed your popular YouTube videos in it. When visitors watch videos from your web site, they stay in your site for longer time. This gets better ranking in search results.

7.Host WordPress blog on your website

Host wordpress blog on your web site and write blogs regularly on topics related to your business. Share these blogs on facebook, google+, twitter and other social bookmarking sites. This create back links from high domain authority social bookmarking sites, thereby increasing your web site search ranking.

7 On Page SEO Techniques to boost search ranking

On Page SEO means focusing on the content of the web site to increase search ranking for your web site. There is no point in trying to optimize your entire website(all pages in it) to one keyword phrase or placing all your keywords in home page(index.html). Doing either of them will reduce your ranking to appear in search results. Create separate web page for each keyword and optimize each page for one particular keyword.

On Page SEO Techniques

This article outlines top 7 on page SEO techniques to boost your web site or blog search ranking ordered by priority.

1. Readable content with Keywords in it

Web page content is the key element not only for the customer but also for the search engine. If the content in your website is not original (copied or modified from other web sites), Google will not consider your content as valuable to be shown in the search results. Write your content in natural language as there is no need to repeat your keyword multiple times in web page. Keyword stuffing may sound unnatural for your customers to read your pages. Make sure that keyword is present in the first paragraph and placed within first 100 words. Add your keyword in alt tag of at least one image in your page.

2.Web Page Load Time

Do you know with sites having flash or lot of high resolution images load slow compared to plain text web sites. If you web page is slow, it decreases search engine ranking of your page significantly. Make sure your page loads with 4-5 seconds. If you have webpage with lot of images consider compressing your image using http://jpeg-optimizer.com/ or https://tinypng.com/

Use Google Webmaster PageSpeed Insight tool or http://gtmetrix.com to analyze if your website is slow.

3.Keyword in Web Page URL

Having the words you want to be found within your domain name or page URLs can help you get better ranking.

4. Title Tag

The title element of a web page should have concise description of a page’s content. This is critical to both user experience and search engine optimization. Google displays the first 50-60 characters of a title tag in search results. Remember to place important keywords at the start of the title tag.

<title>keyword1 – keyword2 | Brand</title>

5. Meta Description Tag

The meta description tag, allows you to suggest search engine how you want your pages to be described in search results. Though this tag may not increase your ranking, it will be shown to your customer in search results. So keywords should be present atleast once in description tag and it should make your customers click your site from the search results. Google display first 150 characters in search results. Below is a

<meta name="description" content="whatever written here will be shown in the search results page">

6.Header Tags

Header tags are a formal way to identify key sections of a web page. Placing your keywords once in h1 tag and h2 tag would increase your ranking. Placing exact keyword phrases in title, meta description, h1 tag, h2 tag and specifying it multiple times in body may signal Google that you are trying black hat SEO technique.

7. Internal Linking and sitemap

Linking to pages within your website is very important for search engine. This informs search engine that the website has lot of relevant content within it. Another important factor which is getting more attention nowadays is linking to high authority sites like wikipedia, forbes, ndtv, etc from your web page. Create sitemap.xml and sitemap.html so that search engine crawler knows the structure of your web site and crawls your pages efficiently. Add Quick Links to your website footer and Related Links sidebar containing links to other pages of your website. Link to category page or subcategory page from product page. If there is no categorization, link back to home page from all other pages.

Avoid locking in Singleton

The Singleton is a useful Design Pattern which allows only one instance of your class. Singleton is implemented by declaring static instance of the object reference within the class

class MySingleton {
static MySingleton *instance;
MySingleton() {
//...
}

public:
MySingleton* getInstance() {
return instance;
}

}

static MySingleton::instance= new MySingleton();

If singleton object is created during loading time itself, no locking is required. But in case of lazy loading, it needs to be guarded with a mutex to avoid multiple object instantiation.

MySingleton* getInstance() {

 //acquire mutex
if (NULL == instance) {
instance = new MySingleton();

 }

  //release mutex
return instance;
}

Every request to getInstance() includes mutex overhead.In order to avoid mutex overhead, double checked locking pattern can be used.

// Double-checked locking -- don't use
MySingleton* getInstance() {
if (NULL == instance) {
//acquire mutex
if (NULL==instance) {
instance = new MySingleton();
}
//release mutex
}
}

This method is not 100% safe because of compiler optimizations and may lead to undefined behavior which is hard to debug. Another technique(safe to use) is to use atomic operations and local variable as specified below.


MySingleton* getInstance() {
MySingleton *localRef = new MySingleton();

  int ret = testandset(&instance, 0, localRef);

  //note testandset function returns old value stored in the variable.
if (0==ret) {
return instance;
}
//some other thread had initialized this.

  delete localRef;

  return instance;
}

Symptoms of bad design

Code Refactoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves its internal structure-Fowler. In order to identify whether legacy software product requires code refactoring, one needs to know whether the existing system design is good or bad. The knowledge of bad design symptom also assists the designer to perform better.

Following are the symptoms of bad design

Rigidity: code/design is hard to change. Simple change requires lot of code changes.

Fragility: code/design is easy to break. code break in unexpected area.

Immobility:Hard to re-use code.

Viscosity:Make easier changes (hack) than fixing issues in-line with the current design.

Complexity: Too much anticipation of future need.

Repetition: Similar code in many places with slight change.

Low Cohesion: Less degree of connectivity among the elements of single class.

High Coupling: Interdependency between modules.

Code Level Optimization Techniques

Some of the techniques mentioned below “arithmetic operators”, “jump table to replace if…elseif”, “faster for loops” makes the code hard to debug, un-portable and un-maintainable. If there is no other way to optimize, then only attempt these techniques.

Use pass by reference for user defined type

Passing parameters by value to functions, result in the complete parameter being copied on to the stack. Pass by value shall be replaced by const references to avoid this data copy. Passing bigger objects as return values also has the same performance issues; instead replace it as OUT parameters for that function.

Pre-compute quantities to speed up run-time calculations

Avoid constant computing inside the loops. Though most of the compilers do this optimization, it is still better if it is handled in our code rather than relying on the compiler.

for (int i=0; i <100; i++) {
    offset = offset + strlen(str);
}
Shall be replaced to 

int size = strlen(str);
for (int i=0; i <100; i++) {
    offset = offset + size;
}

Avoid system calls in time critical section of the code 

System calls are costly as it involves switching into kernel mode from user mode. For instances where two process needs to communicate, using shared memory is better than using message queues of pipes as shared memory does not incur any system calls to send and receive data.

Lazy / Minimal Evaluation 

Lazy or delayed evaluation is the technique of delaying a computation until the result of the computation is actually needed for that code path. 

For example, if the expressions are concatenated using logical ‘AND’ or ‘OR’ operator, the expression is evaluated from left to right. We shall gain CPU cycles by placing the expressions in correct position

Consider the code example

if (strcmp(str, “SYSTEM”) && flag == 1)

{

   //…

}

In the above code segment, strcmp() function takes lot of time and for cases where flag != 1, it still does the comparison wasting lot of CPU cycles. The efficient code is

if (flag ==1 && strcmp(str, “SYSTEM”))

{

   //…

}

The same is applicable for OR logical operator when flag == 1. In general, for expressions using operator &&, make the condition that is most likely to be false the leftmost condition. For expressions using operator ||, make the condition that is most likely to be true the leftmost condition

Frequently executed cases should come first in the switch case or if..elseif statement so that the number of comparisons is reduced for the frequently executed case.

The following switch statement is inefficient as integer datatype, which is used most of the time, is placed in the last case and then string data type. Double data type is seldom used in most of the applications, but it is placed in the first case.

switch(dataType) {
  case typeDouble: { doDoubleAction(); break; }
  case typeDate: {doDateAction();; break; }
  case typeShort: {doShortAction();.; break; }
  case typeString: {doStringAction(); break; }
  case typeTimeStamp: {doTimeStampAction(); break; }
  case typeInt: { doIntAction(); break; }
  default: {doDefaultAction(); break; }
}
This shall be made efficient by keeping the frequently used data types first and followed by least and seldom-used data types.

switch(dataType) {
  case typeInt: {…; break; }
  case typeString: {…; break; }
  case typeShort: {…; break; }
  case typeDouble: {…; break; }
  case typeTimeStamp: {…; break; }
  case typeDate: {…; break; }
  default: {…; break; }
}
Much more elegant way is to implement a jump table using function pointers. Consider the following code

typedef void (*functs)();
functs JumpTable[] = { doIntAction, doStringAction(), doShortAction() /* etc*/} ;

Place your function pointers in the same sequence of dataType enum. The above JumpTable assumes that DataType enum is defined as follows

enum DataType{
typeInt =0,
typeString,
typeShort,
/* other types */
};

To call the appropriate implementation just use the following statement

JumpTable[dataType]();

Now the compare operations are replaced with array indexing operation, which are much faster. Moreover the time taken for every data type is nearly the same as compared to if..elseif and switch() constructs.

Minimize local variables

If the number of local variables in a function is less, then the compiler will be able to fit them into registers, thereby avoiding access to the memory (stack). If no local variables need to be saved on the stack, the compiler need not set up and restore the frame pointer.

Reduce number of parameters

Function calls with large number of parameters may be expensive due to large number of parameter pushes on stack on each call. This is applicable even when struct is passed by value. 

Declare local functions as static

If the function is small enough, it may be inlined without having to maintain an external copy if declared as static.

Avoid using global variables in performance critical code

Global variables are never allocated to registers. Global variables can be changed by assigning them indirectly using a pointer, or by a function call. Hence, the compiler cannot cache the value of a global variable in a register, resulting in extra loads and stores when globals are used. 

Pointer chains

Pointer chains are frequently used to access information in structures. For example, a common code sequence is:

 typedef struct { int x, y, color; } Point;

 typedef struct { Point *pos, int something; } Pixel;

 void initPixel(Pixel*p)

 {

 p->pos->x = 0;

 p->pos->y = 0;

 p->pos->color =0;

 }

However, this code must reload p->pos for each assignment. A better version would cache p->pos in a local variable:

 void initPixel(Pixel *p)

 {

 Point *pos = p->pos;

 pos->x = 0;

 pos->y = 0;

 pos->color = 0;

 }

Another way is to include the Point structure in the Pixel structure, thereby avoiding pointers completely. Some compilers do provide this optimization by default.

Replace frequent read/write with mmap

If the application does lot of read/write calls, then you should seriously consider to convert it into mmap() . This does not incur data copy from kernel to user and vice versa and avoids kernel mode switch for executing the read() or write() system call. You can use fsync() call, once to flush all the data to the disk file after you write all your data into the mapped memory area. 

Place elements together, which are accessed together

When you declare a structure make sure that the data elements are declared in such a way that most frequently accessed elements at the beginning

For example if page element is accessed many times and hasSpace little less and freeNode rarely, then declare the structure as follows.

Struct Node{

Int page;

Int hasSpace;

Int freeNode;

///other types

};

This improves the performance because L1 or L2 cache miss, will not get only the required byte, it also gets one full cache line size of data into the appropriate cache. When page is cached, it also caches hasSpace if cache line is 64 bit.  L1 cache line size is usually 64 bits and for L2, it is 128 bits.

Arithmetic operator

Replacing multiplication and division by shift and add operations.

X * 2 shall be replaced to X+X or X<<1

X * N shall be replaced by X<<I where N is 2 ^ I

X / N shall be replaced by X >>I where N is 2 ^ I

Faster for() loops 

for( i=0; i<10; i++){ … } 

If the code inside the loop does not care about the order of the loop counter, we can do this instead:

for( i=10; i–; ) { … }

This runs faster because it is quicker to process i– as the test condition, which says “Is i non-zero? If so, decrement it and continue”. For the original code, the processor has to calculate “Subtract i from 10. Is the result non-zero? If so, increment i and continue.” 

Prefer int over char and short

If you have an integer value that can fit in a byte, you should still consider using an int to hold the number. This is because, when you use a char, the compiler will first convert the values into integer, perform the operations and then convert back the result to char. Doing so, will increase the memory usage but decreases the CPU cycles 

Advise OS on how it should manage memory pages

Using madvise()  system call, we can specify how the swapping and prefetching should be handled by the operating system. If you are accessing data sequentially, OS can prefetch some pages and keep it ready before the program references it. If program accesses data in some memory location frequently, it shall be locked in physical memory avoiding page swap to disk, using mlock() system call.

Thread Design Techniques

A) Pipeline
Task is divided into multiple sub tasks and each thread is responsible for doing one subtask. Job is passed from one thread to other till it reaches the final state.

B) Master/Servant
Master thread does accept the work and delegates work to its servants. Servants are created on the fly by the master when a work arrives to the master. After finishing the job servants go away. For next work, master creates new servants.

C) Thread Pool
Master thread accepts the work and delegate it to predefined set of servants, called thread pool. This is usually accomplished by using a queuing mechanism in between. Master adds request to the queue and all the threads in the pool removes the request from the queue and handles it iteratively.
