Keyword Stuffing

Sometimes the input tags are used to insert such keywords with hidden attribute so that the user has to read these text and search engine. Again, the color of the page does the same as the text so the user can’t see but see the search engine. Keyword stuffing is often called Keyword Loading. You should avoid doing this if the search engine finds out that the site will be kicked out.

Link Popularity

This is a site to determine what the quality is. This is based on quality inbound links (backlinks). Search engines create their algorithms based on link populace to see where a site will be on the Search Engine Results Page(SERP). 

The difference between quality backlink and only backlink is that Quality Backlink will be on a site similar to your site. For example, if link to w3schools is a quality backlink and if it’s on Facebook, it’s just backlink.

Link farm

Link Firm is a link to each site by opening several websites. For that, the backlinks site increased of each site. If you catch this, the search engine will be able to spam dexing your site.

Spam dexing your site for various reasons, such as by doing link firming, by stuffing keywords, by creating doorway pages, by clicking, by simply saying black hat SEO.

Doorway page

It’s about creating pages with very few lines and only keywords in these lines so search engine finds a lot of keywords. This increases the keyword but does not provide much information for users. If you go to this page, you can link to another page or redirect it to another page. It is known as entry pages, portal pages, jump pages, bridge pages etc.



It’s a technique that shows search engine a kind of content and a different content to the user. In this system, when a request is made for a page on the server, the IP address or user agent sees it and finds that it is a search engine bot/crawler/spider/scooter or a human. When you see spiders, you see a page of one kind and a human one.

Internal Link

This is a link to one page on your site. It’s very important. For example, if you have a series of tutorials on your site, link to the previous page with an Anker text to go from one page to the page. This will serve as a backlink to your site. This increases the page rank. On Wikipedia, you will see how many of them have links to the site on each line.


The traffic on the site is the number of visits to a site. The increase in traffic on a site means that visitors to the site are increasing. Title tag is a very important topic for a web page. Because Search Engine uses the title tag to find a website.

Title Tag

The name or title of an HTML document is known as a title. The title tag tells both the user and the Search Engine what is in the page, meaning a title is a page summary. The web page title must be unique and precise so that it does not match the title of another page on the site.

Title tag location in Search Window

Page titles are first in line when we look at the search results in the browser. Below is a picture showing the location of the title tag, meta tag, and URL of the web site in Search Window.

If the keyword the user searches with is bold edited to the search result, then the full page title will increase the site’s traffic multipletimes.

 <title>…</title> Tag

Html is given in html sms using <title> </title> tag in html documents. Page titles should always be defined in a way that is very similar to the content of the page.


HTML documents should not be given a big title because it causes a lot of unnecessary words to be titles and if a big title is a google. It shows a part of it, but not the whole of it.

Two things to remember in the title tag:

1) It’s better to have a number of titles between 40 and 80,

2) No other tag can be used in the title tag,

The best web page titles should be small, relevant and informative.

the HTML Meta tag is one of the most important tags in SEO. The meta tag provides information about an HTML document to the search engine.

Meta Description

Briefly write what is on the page in the “description” of the Meta ( <meta> s) tag. It gives Google and all Search Engines an idea of what’s on this page. You can give this description in 2/3 lines. Google can take the meta description as a summary of the content on your page. It is said that if the keyword the user searches with is more matched directly with a part of the page content, it can be shown in the Google search results.

Meta Description

If the keyword provided by the user is in this summary ,it will be bolded, as in the above image, the user’s “HTML Tutorial in Bangla” text is bolded in the search results. It gives a hint to the user how much the page is in harmony with what he is looking for. So, please explain the data so that you can see it in the user search results and think that I have the information I need on this page.

It is better to copy and paste a piece of the content on the page to a meta-bonnet, but to write a short summary on the content of the page.

The Meta description of each page varies or the user or search engine will be in trouble when they see multiple pages at once. If you have thousands of pages on your site, it will be complicated to create separate meta-descriptions for each page, so you need to use this technique to create automatic meta-details based on the content of the page.

We know that html documents contain a total of 6 heading tags from h1 to h6. These tags should be specifically monitored for SEO ingot of a web site.

Follow the order of the purity

The text in the heading tag looks a little larger than the normal text. Follow the order of accuracy when using the heading tag. That is, tags for the most important <h1>titles, indicate for some less-than-significant <h2> heading, and even a tag for a few less-than-significant <h3>titles, such as <h6>heading.



It is best to keep the articles in the heading tag when an article is written on a web page. If there are a few paragraphs in one article, it is better to keep one of the headings in each paragraph with this heading tag, so that the user and search engines can guess what is written in the paragraph. It’s never right to give a heading that doesn’t match the paragraph. Heading is a must and a must.

Never should a whole paragraph be placed in the heading tag. It’s not good to use too much heading on a page. If there are 30 lines on one page, 10/12 lines should never be heading. Such additional headings will never yield good results.
