2. Meta Description

A meta description is a short description of the page content. In search engine results what you see at the bottom of the title is a meta description.

Google or any other engine grabs the description text from the text written in the content attribute of the meta tag to which the description name is assigned.

To add meta description to any page just write the text in the content attribute of the meta tag to which description name is assigned as shown below.

<meta name="description" content="If you're a blogger, trying to boost your site's visibility in the search results, then you must read this helpful article on the best SEO tools for bloggers.">

Google has recently revealed that it does not support meta description. But it plays a major role in the page’s click-through rate as one gets informed about what the content page has to offer for the reader.

The length of the Meta description is changed from time to time. It was earlier around 160 characters on desktop and for mobile, it was around 130 characters. But now there is no fixed character limit that can be said perfect.

Google’s public search liaison, Danny Sullivan, Mentioned in their tweet that length varies based on what Google deems to be most useful.

Tips for writing a good meta description tag

⦁ Write little about the things you have served in content
⦁ Add unique meta descriptions containing the targeted keyword
⦁ Add Call To Action Keywords like Apply now, Check out today, Call now, Read now, etc
⦁ Add any discounts or offers you have, if any to attract readers to your page

3. Canonical Tag

Canonical tags

Your Site may have a lot of duplicate pages which is a single page from the human perspective but for search engines, it is a different page with the same content.

For example, you post lots of article on your blog page and once the limit of 10 blog post on a page completed a second page of the blog is made by the CMS(content management system) you use. that case the google webmaster will show you that your blog page 1 and blog page 2 is duplicated.

This makes a big problem for you when search engines are ranking your content. They will get confused and rank each URL separately make your ranking down.

To make yourself safe from this problem you have to tell the search engine that there are other versions of this webpage But this one is the main page that engines need to pay attention to. And here we use the Canonical tag.

The canonical tag is an HTML tag that is used to tell the search engine crawlers that this is the main page of this particular content and others are just pillarizing content around it.

Doing this will help search engine crawlers read your website and rank you better.

4. Image Alternative Text Attribute

Most Important HTML Tags Image Alt Attr

Images are not like Text, for a human it is easy to understand what the image is about or what it is showing. But a search engine can’t understand or read. Making search engines understand our image is crucial for SEO.

<img src="url" alt="Description Goes Here">

To make the search engine read the image we have to use the alt text attribute in the image tag. This way we describe the engine about what is the image all about.

A proper alt tag must be used instead of typing anything in the alt text field as in case if the image doesn’t get loud at all the Alt text is shown in the browser and allow the readers to know what image was there that don’t get load properly.

Tips for writing a good Alt text in the image

⦁ Use a proper description related to the image in the context of content
⦁ Don’t stuff the alt field of the image with content keywords
⦁ Use informative filenames
⦁ Be clear and to the point
⦁ Use 50-55 characters (up to 16 words) in the alt text

Your Content may have some stats, data, or anything from other sites or you just want to point to others’ sites for a particular word in that case use of links and anchor tags comes in the mind.

<a href=www.example.com rel="nofollow">anchor text of link goes here</a>

Most people know about the links but largely don’t know about anchor text.

For SEO purposes linking to another’s domain is important it may be done by just adding a URL or writing a text and attaching it to a URL on which if users click they point to that particular site or site’s page.

How anchor text so important?

An anchor tag helps engines to understand what is the link(URL) and also establish the connection of link and text together.

if someone gives you a link to your site using a good anchor tag, it will help you more on rankings than just a link.

And, if you give a link to your page (inbound link), it will help you increase your DA (Domain Authority) as it makes your content organized which is what the engine loves to see.

⦁ Noindex,nofollow – the search engine will not index the page and even not follow the outgoing URLs

7. Open Graph Meta Tags and Twitter Cards

These tags make sharing of an article on social media in predecided format. If anyone shares the article on their post, these tags will automatically provide the social media title, description, social image, permalink, and everything of the article.
