STEP 1

Update Update Update!

Tip: Use the latest version of the Wordpress! Its always better as they fix up the Vulnerabilities and make it more safe.

How to: As soon as the new version is available, you’ll be notified on your Wordpress Admin Dashboard. Follow the process form there to update it.

STEP 2

Change Username and Password!

Tip: Wordpress provides you the default username and password i.e admin at the time of install so everyone will know your username so and its it would be easy for them to guess your password.

How to: Create a new user from the dashboard and keep an alpha numerical password even include special characters.And then sign in to phpMyAdmin through your webserver account and change user name from “admin” to something of your choice too.

STEP 3

Keep Backups

Tip: Its always good to keep a backup of your blog posts and comments, so that you can revert to the latest contents after a disaster. I suggest you backup often, depending upon your site’s traffic.

How to:There is a Wordpress backup plugin which does a pretty job. You can either email the backup or download it to your computer. Link to plugin here

Manual backup is even better to do a complete backup of your database.

STEP 4

Stop brute force attacks

Tip: Brute force is multiple attempt of logins. You can stop it!

How to: Use login lockdown plugin, its and excellent plugin which monitors login attempts to your site. It checks how many times in a short period of time the same IP range has tried to login and if in that time a particular IP exceeds the attempts allowed then this sweet plugin will lock down access privileges for a time period you set.

STEP 5

Password protect

Tip: Password protect you wp-admin

How to: Use the askapache password protect plugin It protects your Wordpress wp-admin folder which adds another layer of security by requiring a set of valid Username and Password to gain access to anything in the /wp-admin/ folder.

Easy to use, all you need to do is to create another username and password. Here, you added some more protection. It works by writing a new .htaccess file for that folder, and encrypts your new password. Highly recommended.

STEP 6

Hide Your Contents

Tip: Did you ever login http://www.yourdomain.com/wp-contents/plugins/ on your browser? Do it! You will see the list of your plugins now its again cake walk for the hackers to look at your plugin and see if you are using one with known security vulnerabilities and exploit them. So hide it

How to: Just make a blank index.html on your computer, upload it using the your ftp and put it in the /plugins/ folder and its all fixed. Its also good to add it in your /themes/ folder too. It works!

STEP 7

Block search engines

Tip: Block search engines from crawling up your wp-folders as there is no need to have all your Wordpress files indexed, so its probably better to block them so there is no need to having all your Wordpress files indexed, so its probably better to block them so when people search they do not see those files.

How To: You can block search engines from crawling your wp- folders by blocking access via robots.txt file.

Simply add this line: Disallow: /wp-*

If you are lazy again to do this then go ahead and use KB robots.txt plugin

The Google PageRank, algorithm and its working

Introduction

Page Rank is considered very important by many Search Engine Optimisation (SEO) experts, though it does not place an important role in Google search results. But, still having a good page rank determines the importance of a link or web page. Google too gives the Page rank a Preference when multiple factors are considered.
Page Rank is one of the methods Google uses to determine a page’s relevance or importance. It is only one part of the story when it comes to the Google listing, but the other aspects are discussed elsewhere (and are ever changing) though Page Rank says nothing about the content or size of a page.
Google PageRank is displayed in Google Toolbar ranging from 0 – 10 whereas the actual Page rank differs in Floating point numbers shown below.
Google Toolbar PageRank
Real PageRank
0 0 – 10
1 10 – 100
2 100 – 1,000
3 1,000 – 10,000
4 10,000 – 100,000
5 100,000 – 1,000,000
and so on…
The Page Rank changes every time Google does its indexing.It is not convenient to show the Page Rank in large digits and to update it frequently. So, Google Page Rank and Back links are updated in the Toolbar mostly in a time span of 1-3 months.

So, what is PageRank?
  • PageRank is only one of numerous methods Google uses to determine a page’s relevance or importance.
  • PageRank evaluates two things: how many links there are to a web page from other pages, and the quality of the linking sites.
  • The Google PageRank algorithm it’s established PR across all of the outbound links. Put differently, if you had a web page with a PR6 and had 1 link on it, the site linked to would get a fair amount of PR value. But, if you had 40 links on that page, each individual link would only get a fraction of the value.
  • From this, we could conclude that a link from a page with P̸ and 5 outbound links is worth more than a link from a page with P̼ and 100 outbound links. The PageRank of a page that links to yours is important but the number of links on that page is also important. The more links there are on a page, the less PageRank value your page will receive from it.
How the PageRank is calculated
  1. PageRank is based on incoming links, but not just on the number of them – relevance and quality are important (in terms of the PageRank of sites, which link to a given site).
  2. It often takes two full monthly updates for all of your incoming links to be discovered, counted, calculated and displayed as backlinks
  3. PageRank does not rank web sites as a whole, but is determined for each page individually.
  4. Google calculates pages PRs permanently, but we see the update once every few months .
  5. PR(A) = (1-d) + d [PR(t1)/C(t1) + … + PR(tn)/C(tn)]. This is the formula to calculate the PageRank (of Page A).
Lets make it simple to understand
  1. PR(͉) – Each page has a notion of its own self-importance.That’s PR for the first page
  2. PR(TN) – That’s PR of the Nth number of page.
  3. C(Tn) – Its the total outgoing links from a page. The count, or number, of outgoing links for page 1 is C(T1), C(Tn) for n number of pages.
  4. d – All these fractions of votes are added together but, to stop the other pages having too much influence, this total vote is “damped down” by multiplying it by 0.85 (the factor “d”).
  5. (1 – d) – The (1 – d) bit at the beginning is a bit of probability so the “sum of all web pages’ PageRanks will be one”: it adds in the bit lost by the d It also means that if a page has no links to it (no backlinks) even then it will still get a small PR of 0.15 (i.e. 1 – 0.85). (Aside: the Google paper says “the sum of all pages” but they mean the “the normalised sum” – otherwise known as “the average” to you and me.)

Important factors for PageRank
  • Incoming Links from popular sites are important. If pages linking to you have a high PageRank then your page gains some part of their reputation.
  • Site can be banned if it links to banned sites.Be extremely careful of any out-going links from your site. Don’t link to bad neighborhoods (link farms, banned sites, etc.) Google will penalize you for bad links so always check the PageRank of the sites you’re linking to from your site.
  • Illegal activities will penalize your PageRank and possibly ban your site from Google.Hidden text, deceptive redirects, cloaking, automated link exchanges, or anything else against Google’s quality guidelines can ban your site from Google.
  • Different pages from a site can have different Page Rank.Search engines crawl and index web pages not websites, that is why your page rank may vary from page to page within your website.
  • Content is not taken into account when PageRank is calculated. Content is taken into account when you actually perform a search for specific search terms.
  • Links marked with nofollow-attribute don’t contribute to Google PageRank.Google implemented a new value, “nofollow”, for the rel attribute of HTML link and anchor elements, so that website builders and bloggers can make links that Google will not consider for the purposes of PageRank — they are links that no longer constitute a “vote” in the PageRank system.
  • Bad incoming links don’t have impact on Page Rank.Where the links come from doesn’t matter. Sites are not penalized because of where the links come from
  • Google penalizes link farms.Google is only concerned with pages of over 100 outgoing links. Google considers overly linked pages to be link farms, and they are penalized as such.
List of PageRank Tools

We have got our own PageRank calculator which shows the current PageRank of your site with its Alexa Rank and Average backlinks from most popular search Engines.
Google PageRank Inspector
Google PageRank inspector is PHP scripts that can seek all of your website, include out linked page or not, and display Pagerank value for each of your website pages.
PageRank Decoder
This little tool is not too much different then a tool that tells you your PageRank, however it allows you to organize your sites (with PR information) in a visual network and then correspondingly connect them with arrows. You can move them around like cards, connect them or not, and even delete them by throwing them in a trash can.
