Why can't I use robots.txt to block my file?

If you use robots.txt, Google will not crawl a page; however, if it finds a link to your page on another site, with descriptive text, it might generate a search result from that. If you have included a “noindex” tag on the page, Google won’t see it, because Google must crawl (fetch) the page in order to see that tag, but Google won’t fetch your page if there’s a robots.txt file blocking it! Therefore, you should let Google crawl the page and see the “noindex” tag or header. It sounds counterintuitive, but you need to let Google try to fetch the page and fail (because of password protection) or see the “noindex” tag  to ensure it’s omitted from search results.

This does not apply to images; for images, robots.txt is the correct way to block images from search results.

Know About Google Analytics Cookies

There can be up to five different cookies that a website with Google Analytics tracking code sets on your computer. However, four of them are automatically set, while the fifth one is an optional cookie. Let’s take a look at each one.

__utma set for life time (2038)
This cookie keeps track of the number of times a visitor has been to the site pertaining to the cookie, when their first visit was, and when their last visit occurred. Google Analytics uses the information from this cookie to calculate things like Days and Visits to purchase.

__utmb expire when close browser
__utmc expires after 30 minute
working together to calculate how long a visit takes. __utmb takes a timestamp of the exact moment in time when a visitor enters a site, while __utmc takes a timestamp of the exact moment in time when a visitor leaves a site. __utmb expires at the end of the session. __utmc waits 30 minutes, and then it expires. You see, __utmc has no way of knowing when a user closes their browser or leaves a website, so it waits 30 minutes for another pageview to happen, and if it doesn’t, it expires.

__utmz expires in 15,768,000 seconds or 6 months
__utmz keeps track of where the visitor came from, what search engine you used, what link you clicked on, what keyword you used, and where they were in the world when you accessed a website.

__utmv as per the user requirement
If you are making use of the user-defined report in Google Analytics, and have coded something on your site for some custom segmentation, the __utmv cookie gets set on the person’s computer.

Google Analytics Basic Study Guide

Audience Overview
=================

Session = Visit
Total number of sessions within the date range. (Count of no. of 30 minute sessions)

%New Sessions
Percantage of First Time Visit

Pages/Visit = Pages/Session
The average number of pages viewed during a session

Avg. Session Duration
The average length of a Session.

Users = Unique Visitor
Total number of users in selected time frame

New Users
First time users (count with the help of __utma)

PageViews
Pageviews is the total number of pages viewed. Repeated views of a single page are also counted.

Unique Pageviews
A->B->C->A (here 3 is unique pageviews and total pageviews are 4)

New Visit = New Users
First time users (count with the help of __utma)

Bounce Rate = %Bounce Rate
Bounce Rate is the percentage of single-page visits

%Exit = Exit Rate
%Exit is (number of exits) / (number of pageviews) for the page or set of pages. It indicates how often users exit from that page or set of pages when they view the page(s).

Entrance vs Sessions
Entrance Apply on Event while Sessions Apply on Page
e.g.
Enter ->Page A->Page B->Exit
Entrance =1, Session=1, Pageviews=1

Enter->Event1->PageB->Exit
Entrance=1, Session=0, Pageviews=1

Image Optimization

Image Optimization
=================

• Informative Filenames
• Alt Tag
• Don't Scale Image
• Eliminate unnecessary image resources
• Leverage CSS3 effects where possible
• Use web fonts instead of encoding text in images

Vector vs. Raster images

• Vector images are ideal for images that consist of geometric shapes
• Vector images are zoom and resolution-independent
• Raster images should be used for complex scenes with lots of irregular shapes and details
  
  

Vector graphics: use lines, points, and polygons to represent an image.
Raster graphics: represent an image by encoding the individual values of each pixel within a rectangular grid.

Pixels
=================
there can be two types of pixel
1. CSS Pixel
2. Device Pixel
Note:-

• A single CSS pixel may contain multiple device pixels
• High resolution images require significantly higher number of pixels and bytes

Optimizing vector images
=============================

Screen resolution	Total pixels	Uncompressed filesize (4 bytes per pixel)
1x	100 x 100 = 10,000	40,000 bytes
2x	100 x 100 x 4 = 40,000	160,000 bytes
3x	100 x 100 x 9 = 90,000	360,000 bytes

• SVG is an XML-based image format
• SVG files should be minified to reduce their size
• SVG files should be compressed with GZIP

Exported from Adobe Illustrator

Optimizing raster images
=============================
1. A raster image is a grid of pixels
2. Each pixel encodes color and transparency information
3. Image compressors use a variety of techniques to reduce the number of required bits per pixel to reduce file size of the image

• Each pixel stores the “RGBA” values: (R) red channel, (G) green channel, (B) blue channel, and (A) alpha (transparency) channel.
• Internally, the browser allocates 256 values (shades) for each channel

WebP
An open-source image format that provides 30% better image compression.

Google Search Working
Occasionally, fluctuation in search results is the result of differences in our data centers. When you perform a Google search, your query is sent to a Google data center in order to retrieve search results. There are numerous data centers, and many factors (such as geographic location and search traffic) determine where a query is sent. Because not all of our data centers are updated simultaneously, it's possible to see slightly different search results depending on which data center handles your query.

Speedy load time. Google says this should be five seconds or less.

Why Responsive
1. It saves resources for both your site and Google's crawlers

SEO
==============
Note:
Be sure not to block the crawling of any Googlebot of the page assets (CSS, JavaScript, and images) using robots.txt or otherwise. Being able to access these external files fully will help our algorithms detect your site's responsive web design configuration and treat it appropriately.
