“Tips for Search Engine On Page Optimization 21-34 Seo Tactics”
21. Helpful “Supplementary Content”: According to a now-public Google Rater Guidelines Document, helpful supplementary content is an indicator of a page’s quality (and therefore, Google ranking).
Examples include currency converters, loan interest calculators and interactive recipes.
22. Historical Page Updates: How often has the page been updated over time? Daily, weekly, every 5 years? Frequency of page updates also play a role in freshness.
23. Keyword Prominence: Having a keyword appear in the first 100 words of a page’s content is correlated to first page Google rankings.
24. Keyword in H2, H3 Tags: Having your keyword appear as a subheading in H2 or H3 format may be another weak relevancy signal.
25. Outbound Link Quality: Many SEOs think that linking out to authority sites helps send trust signals to Google. And this is backed up by a recent industry study.
26. Outbound Link Theme: According to The Hillop Algorithm, Google may use the content of the pages you link to as a relevancy signal. For example, if you have a page about cars that links to movie-related pages, this may tell Google that your page is about the movie Cars, not the automobile.
27. Grammar and Spelling: Proper grammar and spelling is a quality signal, although Cutts gave mixed messages a few years back on whether or not this was important.
28. Syndicated Content: Is the content on the page original? If it’s scraped or copied from an indexed page it won’t rank as well… or may not get indexed at all.
29. Mobile-Friendly Update: Often referred to as “Mobilegeddon“, this update rewarded pages that were properly optimized for mobile devices. Mobile Usability: Websites that mobile users can easily use may have an edge in Google’s “Mobile-first Index”.
30. Number of Internal Links Pointing to Page: The number of internal links to a page indicates its importance relative to other pages on the site.
31. “Hidden” Content on Mobile: Hidden content on mobile devices may not get indexed (or may not be weighed as heavily) vs. fully visible content. However, a Googler recently stated that hidden content is OK. But also said that in the same video, “…if it’s critical content it should be visible…”.
32. Content Hidden Behind Tabs: Google has said, Do users need to click on a tab to reveal some of the content on your page? that this content “may not be indexed”.
33. Quality of Internal Links Pointing to Page: Internal links from authoritative pages on domain have a stronger effect than pages with no or low PageRank.
34. Broken Links: Having too many broken links on a page may be a sign of a neglected or abandoned site. The Google Rater Guidelines Document uses broken links as one was to assess a homepage quality.
