Seo can also target specialized searches such as image search, local search, and industry-exact vertical search engines.

Keyword Use in Title Tag

The about critical position to put your Keywords into. Put your keyphrases in your title tag, and remember to optimize each page individually (Ex.. don't overstuff your title tag, and have unequal title tags since each page that reflect the content of that particular page - otherwise, you may suffer from a duplicative content exclusion and discover yourself in the supplemental results).

Keyword Use in Body Text

Duh. If your keyword or keyphrase isn't refer toed at least once in the body text of the web page, then it does not seem your page is very significant to that keyphrase, now does it? But don't get all caught up in the keyphrase density myth - there is no magic number of times it should be visible. Make sense to readers, and it will formulate impression to the search engines.

Relationship of Body Text Content to Keywords (Topic Analysis)

Google is smarter than you give them credit so that, and just stuffing a keyphrase into a completely unrelated page won't do you a great deal, if any respected. Your page should be on a topic which is semantically related to the keyphrase which you are targeting in your title tag.

Keyword Use in H1 Tag

Oh, so that years the naysayers have been telling me that H1 tag keyphrase use meant nothing and that I was an idiot for thinking otherwise. Correctly the verdict is in and this is the fourth approximately valuable thing according to the SEOMoz article. At this point, therefore, we have self-instructed to put your key phrase in your title tag, embed it in your body text, which body text is topically or semantically related to the keyphrase, and head up the body text with an H1 containing the keyphrase.

Keyword Use in Domain Name

This is one that I disagree with. I have seen completely no evidence of this at all. Do a simple search on the internet so that most any search term, and chances are the top results do not have the search query in the domain name. I presume this may have minor leverage, but don't go and change your domain whereas of it. Seriously, you have a great deal more to lose (such as age of domain, inbound linkage, site reputation, etc.) I regularly spot clients at the top of Google with domain names containing nothing near the significant search terms.

Keyword Use in Page URL

This is what I have called "descriptive file naming" so that a number of years. I suspect it is of some worthiness, again, however, is more of a factor when setting up a new domain than would be so that an existing domain with high pagerank and inbound linkage. Changing your internal url's so that the sole purpose of meeting this criterion again is very risky, for the same reasons bring uped above.

Keyword Use in H2, H3, H... Tags

Well if it works since H1, why not since H2, H3, H4, H5 ?

Keyword Use in ALT Attributes and Image Titles

SEOMoz incorrectly calls them an ALT tag, but it is not a tag, the ALT is an attribute of the IMG tag. Semantics parenthesis, I have confidence in this to be strongly effective, I would have ranked this above the URL and domain name part. Experience has shown me that image optimization (image file name, alt attribute, and title) is a glorious way to create a page more proper to a desired search query.

Keyword Use in Bold - Strong Tags

I always use this approach, as correctly as keyword use within the EM (italics) tag. I believe this to be a moderately supreme thing as it helps give emphasis to to Google what your page is about, and what you consider exceptional. Rigorously on my short list of things to do since "on page" search engine optimization.

Keyword Use in Meta Description Tag

Again, one of my "big four" so that on page optimization. The "big 4" being: title tag, meta description, H1, and image ALT attributes. I don't bring to attention body text in my big four as I think that is self evident. Certainly superior, and again, each page should have custom title and meta description tags.
