Write concise text
Aim for short but descriptive text-usually a few words or a short phrase.
Writing long anchor text, such as a lengthy sentence or short paragraph of text.
Format links so they're easy to spot
Make it easy for users to distinguish between regular text and the anchor text of your links. Your content becomes less useful if users miss the links or accidentally click them.
Using CSS or text styling that make links look just like regular text.
Think about anchor text for internal links too
You may usually think about linking in terms of pointing to outside websites, but paying more attention to the anchor text used for internal links can help users and Google navigate your site better.
Using excessively keyword-filled or lengthy anchor text just for search engines.
Creating unnecessary links that don't help with the user's navigation of the site.
Be careful who you link to
You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.
Another example when the nofollow attribute can come handy are widget links. If you are using a third party's widget to enrich the experience of your site and engage users, check if it contains any links that you did not intend to place on your site along with the widget. Some widgets may add links to your site which are not your editorial choice and contain anchor text that you as a website owner may not control. If removing such unwanted links from the widget is not possible, you can always disable them with nofollow. If you create a widget for functionality or content that you provide, make sure to include the nofollow on links in the default code snippet.
Lastly, if you're interested in nofollowing all of the links on a page, you can add the tag inside the tag for the page. You can find more details about robots meta tags in our documentation.
Combat comment spam with nofollow
To tell Google not to follow or pass your page's reputation to the pages linked, set the value of the rel attribute of a link to nofollow or ugc. Nofollowing a link means adding rel="nofollow" or a more specific attribute such as ugc inside the link's anchor tag, as shown here:

When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.

Automatically add nofollow to comment columns and message boards
Many blogging software packages automatically nofollow user comments, but those that don't can most likely be manually edited to do this. This advice also goes for other areas of your site that may involve user-generated content, such as guest books, forums, shout-boards, referrer listings, etc. If you're willing to vouch for links added by third parties (for example, if a commenter is trusted on your site), then there's no need to use nofollow on links; however, linking to sites that Google considers spammy can affect the reputation of your own site. The Google Search Central documentation has more tips on avoiding comment spam, for example by using CAPTCHAs and turning on comment moderation.

Optimize your images
Use HTML images
Use HTML image elements to embed images in your content.

Use the alt attribute
Provide a descriptive filename and alt attribute description for images. The alt attribute allows you to specify alternative text for the image if it cannot be displayed for some reason.

Why use this attribute? If a user is viewing your site using assistive technologies, such as a screen reader, the contents of the alt attribute provide information about the picture.
Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Images to better understand your images.
Use brief but descriptive filenames and alt text
Like many of the other parts of the page targeted for optimization, filenames and alt text are best when they're short, but descriptive.
Using generic filenames like image1.jpg, pic.gif, 1.jpg when possible—if your site has thousands of images you might want to consider automating the naming of the images.
Writing extremely lengthy filenames.
Stuffing keywords into alt text or copying and pasting entire sentences.
Supply alt text when using images as links
If you do decide to use an image as a link, filling out its alt text helps Google understand more about the page you're linking to. Imagine that you're writing anchor text for a text link.
Writing excessively long alt text that would be considered spammy.
Using only image links for your site's navigation.
Help search engines find your images
An Image sitemap can provide Google with more information about the images found on your site. This increases the likelihood that your images can be found in Google Images results. The structure of this file is similar to the XML sitemap file for your web pages.
Use standard image formats
Use commonly supported filetypes; most browsers support JPEG, GIF, PNG, BMP and WebP image formats. It's also a good idea to have the extension of your filename match with the file type.
Make your site mobile-friendly
The world is mobile today. Most people are searching on Google using a mobile device. The desktop version of a site might be difficult to view and use on a mobile device. As a result, having a mobile ready site is critical to your online presence. In fact, starting in late 2016, Google has begun experiments to primarily use the mobile version of a site's content for ranking, parsing structured data, and generating snippets.
Understand the difference between devices
Smartphone - In this document, "mobile" or "mobile devices" refers to smartphones, such as devices running Android, iPhone, or Windows Phone. Mobile browsers are similar to desktop browsers in that they can render a broad set of the HTML5 specification, although their screen size is smaller and in almost all cases their default orientation is vertical.
Tablet - We consider tablets as devices in their own class, so when we speak of mobile devices, we generally do not include tablets in the definition. Tablets tend to have larger screens, which means that, unless you offer tablet-optimized content, you can assume that users expect to see your site as it would look on a desktop browser rather than on a smartphone browser.
Multimedia phone - These are phones with browsers that are able to render pages coded to meet XHTML standards, support HTML5 Markup, JavaScript/ECMAScript but might not support some of the extension APIs in the HTML5 standard. This generally describes the browser in most 3G-ready phones that are not smartphones.
Feature phones - On these phones, browsers lack the capability to render normal desktop web pages coded using standard HTML. This includes browsers that render only cHTML (iMode), WML, XHTML-MP, etc.
