SEO checklist:

SEO	Művelet	fontosság
Kulcsszavak
Kulccszavak a <title> tagben	Az egyik legfontosabb paraméter. Itt kell elhelyezni a legfontosabb kulcsszavakat. Lehetőség szerint a kulcsszó a kifejezés elejéhez legyen közel. A cím legyen rövid - 5-7 szó.	3
Kulcsszó sűrűség a dokumentumban	A nagy kulcsszavak legyenek a szöveg 3-7 %-ban. 1-2% kevés. 10% felett már a kulcsszavak túlburjánzását jelentik, ami csökkenti az oldal relevanciáját.	3
Kulcszó a linkekben	A befelé jövő linkek és a kifelé mutató linkek esetén egyaránt fontos a kulcszsavak használata	3
Kulcsszavaj a <H1> <H2> headerekben	Erre a helyre tehetünk sok kulcsszót.	3
Kulcsszó higítás	Ha nagy számú kulcsszót használunk, akkor az egyes kulcsszavaknak a használhatósága csökken. ezt hívják higításnak.	-2
Kulcsszó ömlesztés	Ha az oldalon 10% felett van a kulcsszavak száma, akkor kulcsszó ömlesztésről beszélünk és büntetendő. Kitiltást jelenthet a keresőből.	-3
Linkek - belső, kifelé mutató, befelé jövő
Anchor text of inbound links	As discussed in the Keywords section, this is one of the most important factors for good rankings. It is best if you have a keyword in the anchor text but even if you don't, it is still OK.	3
Origin of inbound links	Besides the anchor text, it is important if the site that links to you is a reputable one or not. Generally sites with greater Google PR are considered reputable.	3
Links from similar sites	Having links from similar sites is very, very useful. It indicates that the competition is voting for you and you are popular within your topical community.	3
Number of backlinks	Generally the more backlinks, the better. But the reputation of the sites that link to you is more important than their number. Also important is their anchor text, is there a keyword in it, how old are they, etc.	3
Inbound links from link farms and other suspicious sites	This does not affect you in any way, provided that the links are not reciprocal. The idea is that it is beyond your control to define what a link farm links to, so you don't get penalized when such sites link to you because this is not your fault but in any case you'd better stay away from link farms and similar suspicious sites.	0
Outbound links to link farms and other suspicious sites	Unlike inbound links from link farms and other suspicious sites, outbound links to bad neighbors can drown you. You need periodically to check the status of the sites you link to because sometimes good sites become bad neighbors and vice versa.	-3
Cross-linking	Cross-linking occurs when site A links to site B, site B links to site C and site C links back to site A. This is the simplest example but more complex schemes are possible. Cross-linking looks like disguised reciprocal link trading and is penalized.	-3
Content
Unique content	Having more content (relevant content, which is different from the content on other sites both in wording and topics) is a real boost for your site's rankings.	3
Frequency of content change	Frequent changes are favored. It is great when you constantly add new content but it is not so great when you only make small updates to existing content.	3
Keywords font size	When a keyword in the document text is in a larger font size in comparison to other on-page text, this makes it more noticeable, so therefore it is more important than the rest of the text. The same applies to headings h1, h2, etc.), which generally are in larger font size than the rest of the text.	2
Invisible text	This is a black hat SEO practice and when spiders discover that you have text specially for them but not for humans, don't be surprised by the penalty.	-3
Cloaking	Cloaking is another illegal technique, which partially involves content separation because spiders see one page (highly-optimized, of course), and everybody else is presented with another version of the same page.	-3
Doorway pages	Creating pages that aim to trick spiders that your site is a highly-relevant one when it is not, is another way to get the kick from search engines.	-3
Duplicate content	When you have the same content on several pages on the site, this will not make your site look larger because the duplicate content penalty kicks in. To a lesser degree duplicate content applies to pages that reside on other sites but obviously these cases are not always banned - i.e. article directories or mirror sites do exist and prosper.	-3
Visual Extras
Flash	A Flash alkalmazásokat a keresők nem nayon indexelik (már lehet, hogy igen) Célszerű alternatív szövegeket használni ebben az esetbenalternative.	-2
A Flashwebsite	A SEO a Flasben megírt teljes website-okon nemigen boldogul.	-3
Domains, URLs, Etc
Site Accessibility	Another fundamental issue, which that is often neglected. If the site (or separate pages) is unaccessible because of broken links, 404 errors, password-protected areas and other similar reasons, then the site simply can't be indexed.	3
Sitemap	It is great to have a complete and up-to-date sitemap, spiders love it, no matter if it is a plain old HTML sitemap or the special Google sitemap format.	2
Adsense will boost your ranking	Adsense is not related in any way to SEO ranking. Google will definitely not give you a ranking bonus because of hosting Adsense ads. Adsense might boost your income but this has nothing to do with your search rankings.	0
Adwords will boost your ranking	Similarly to Adsense, Adwords has nothing to do with your search rankings. Adwords will bring more traffic to your site but this will not affect your rankings in whatsoever way.	0
Bans in robots.txt	If indexing of a considerable portion of the site is banned, this is likely to affect the nonbanned part as well because spiders will come less frequently to a "noindex" site.	-2
Redirects (301 and 302)	When not applied properly, redirects can hurt a lot - the target page might not open, or worse - a redirect can be regarded as a black hat technique, when the visitor is immediately taken to a different page.	-3
