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 Image Search to better understand your images.
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 Webmaster Help Center has more tips on avoiding comment spam40, for example by using CAPTCHAs and turning on comment moderation.
Google doesn't always include a whole paragraph of text in the Featured Snippet. If you add "Step 1," "Step 2," "Step 3," etc. to the start of each HTML heading within your content (for example, within your H2 tags), Google will sometimes just list out your headings within the Featured Snippet. I've started to see this happen more and more in keywords beginning with "how to".
The Featured Snippet section appearing inside the first page of Google is an incredibly important section to have your content placed within. I did a study of over 5,000 keywords where HubSpot.com ranked on page 1 and there was a Featured Snippet being displayed. What I found was that when HubSpot.com was ranking in the Featured Snippet, the average click-through rate to the website increased by over 114%.
Google’s local search results are displayed within Google Maps after a user searches for a keyword that includes a location, such as “pizza New York.” Landing within Google’s local search results requires that you have a Google My Business account. This is key for brick-and-mortar-based businesses because it puts your business in front of local people ready to buy.
