Page Title

Page Title : Basics of Electromagnetism and special relativity


Your page title does not exceed 60 characters. It's fine.

Knowledge Base
A title tag is an HTML element that specifies the title of a web page. Title tags are displayed on search engine results pages (SERPs) as the clickable headline for a given result, and are important for usability, SEO, and social sharing. The title tag of a web page is meant to be an accurate and concise description of the content of a page. Search engines typically display the first 50-60 characters of a title tag. If you keep your titles under 60 characters, our research suggests that you can expect about 90% of your titles to display properly. There is no exact character limit, because characters can vary in width and most display titles max out at 600 pixels.

Meta Description

Meta Description : Basics of electromagnetism and special relativity, source, origin of magnetism, magnetic field, forces, relativistic electromagnetism, magnetism and special relativity, Edward M. Purcell Electricity and Magnetism in SI units, relativistic mass, relativistic energy.


Your meta description exceeds 150 characters. It's not good.

Knowledge Base
Meta descriptions are HTML attributes that provide concise explanations of the contents of web pages. Meta descriptions are commonly used on search engine result pages (SERPs) to display preview snippets for a given page. While not important to search engine rankings, they are extremely important in gaining user click-through from SERPs. These short paragraphs are a webmaster’s opportunity to advertise content to searchers and to let them know exactly whether the given page contains the information they're looking for. The meta description should employ the keywords intelligently, but also create a compelling description that a searcher will want to click. Direct relevance to the page and uniqueness between each page’s meta description is key. The description should optimally be between 150-160 characters.

Knowledge Base
SEO keywords are the key words and phrases in your web content that make it possible for people to find your site via search engines. A website that is well optimized for search engines speaks the same language as its potential visitor base with keywords for SEO that help connect searchers to your site. Keywords are one of the main elements of SEO basics.

HTML Headings

H1(1)

  • Basics of Electromagnetism and special relativity

Knowledge Base
The heading structure of your pages is one of the very important aspects of on-page SEO. It defines which parts of your content are important, and how they’re interconnected.

The most important heading on the page should be the H1.
There is usually only one H1 on any page.
Sub-headings should be H2’s, sub-sub-headings should be H3’s, etc.
Each heading should contain valuable keywords, if not, it’s a wasted heading.
In longer pieces of content, a heading is what helps a reader skip to the parts that they find interesting.

Knowledge Base

NoIndex : The noindex directive is an often used value in a meta tag that can be added to the HTML source code of a webpage to suggest to search engines (most notably Google) to not include that particular page in its list of search results.

By default, a webpage is set to “index.” You should add a <meta name="robots" content="noindex" /> directive to a webpage in the <head> section of the HTML if you do not want search engines to crawl a given page and include it in the SERPs (Search Engine Results Pages).

DoFollow & NoFollow : The nofollow directive is an often used value in a meta tag that can be added to the HTML source code of a webpage to suggest to search engines not to pass link equity through any links on a given webpage.

By default, links are set to “follow.” You would set a link to “nofollow” in this way: <a href="http://www.example.com/" rel="nofollow">Anchor Text</a> if you want to suggest to Google that the hyperlink should not pass any link equity/SEO value to the link target.

SEO Friendly Links

Links of your site are SEO friendly.

Knowledge Base
A URL is human-readable text that was designed to replace the numbers (IP addresses) that computers use to communicate with servers. They also identify the file structure on the given website.

URLs should:
1) Use hyphens to separate words when necessary for readability. They should not use underscores, spaces, or any other characters to separate words. Overuse of hyphens in URLs can be seen as spammy, so it’s best to use caution and limit hyphen use in URLs when possible.
2) Never be longer than 2,048 characters; otherwise Internet Explorer will not be able to load the page.
3) Avoid the use of parameters, if possible. If parameters need to be used, they should be limited to two or less.

Image 'alt' Test

Your site does not have any image without alt text.

Knowledge Base
Images can be used to bring in organic traffic via search engine image results. But in order for this to happen, they need to be optimized accordingly. The required alt attribute specifies an alternate text for an image. For any image on your site, the alt tag should describe what’s on it.

DOC Type

DOC Type : <!doctype html>


Page has doc type.

Knowledge Base
The doctype document is not having any influence on your SEO job. However, make sure to add the tag on all pages. Without the doctype declaration you won’t be able to check the validity of your documents.

Deprecated HTML Tag

Your site does not have any depreciated HTML tag.

Knowledge Base
Older HTML tags and attributes that have been superseded by other more functional or flexible alternatives (whether as HTML or as CSS ) are declared as deprecated in HTML4 by the W3C - the consortium that sets the HTML standards. Browsers should continue to support deprecated tags and attributes, but eventually these tags are likely to become obsolete and so future support cannot be guaranteed.

HTML Page Size

HTML Page Size : 25 KB


HTML page size is <= 100KB

Knowledge Base
Huge pages (over 100 K – which is the standard established long ago) can account for a lot of user challenges and decrease the bot’s crawl rate and depth: note that the bot works on a budget – if it spends too much time crawling your huge images or PDFs, there will be no time left to visit your other pages.

How to reduce your page size:
1) Move your CSS and JS code to external files.
2) Use SOC (Source Ordered Content) to ensure that text content is the first to load: i.e. text content is on top of the source code (this will ensure that both bots and people have something to read waiting for the all the page elements to load).
3) Reduce or compress your images and media files

GZIP Compression

GZIP Compressed Size : 7 KB


GZIP compression is enabled.

Knowledge Base
GZIP is a generic compressor that can be applied to any stream of bytes: under the hood it remembers some of the previously seen content and attempts to find and replace duplicate data fragments in an efficient way - for the curious, great low-level explanation of GZIP. However, in practice, GZIP performs best on text-based content, often achieving compression rates of as high as 70-90% for larger files, whereas running GZIP on assets that are already compressed via alternative algorithms (e.g. most image formats) yields little to no improvement. It is recommended that your GZIP compressed page size should be <=33 KB

IP Canonicalization Test

Site failed IP canonicalization test.

Knowledge Base
When a search engine spider indexes a website, it gathers as much information about the website as possible. This may also include the IP address. Why is that a problem? For starters, if you have multiple domain names under one IP address, the search engine could possibly label one the websites as duplicate content. This may not always happen, but it is important to remember that search engines are primarily composed of robots and may overlook simple mistakes that can easily be detected by an average human.

URL Canonicalization Test

Site passed URL canonicalization test.

Knowledge Base
Rel=canonical is a way to specify the preferred version of resources with duplicate content. It will not prevent your duplicates from being crawled and it will not prevent search engines from indexing your content. Instead it serves as a suggestion to search engines on which content it should prefer in the search results in case there are two or more documents that are identical or very similar.

Plain Text Email Test

Site passed plain text email test. No plain text email found.

Knowledge Base
Any e-mail address posted in public is likely to be automatically collected by computer software used by bulk emailers (a process known as e-mail address harvesting). A spam harvester can read through the pages in your site and extract plaintext email addresses which are then added to bulk marketing databases (resulting in more inbox spam). There are several methods for email obfuscation.
